Twenty-seven long-term psychiatric inpatients maintained on neuroleptics with concomitant antiparkinsonian medication were entered into a study in which anticholinergic medication was gradually withdrawn in a randomized double-blind within-subjects design. The extrapyramidal symptoms of each patient were compared when taking their usual anticholinergic medication, when taking placebo and when taking no antiparkinsonian drug. The relapse rate on no medication was 14%, and if patients relapsed on no medication they also relapsed on placebo. The relapse rate was not significantly different on active medication. Nor were there significant differences in ratings of parkinsonism or dyskinesia. The lack of difference between double-blind and overt withdrawal does not mean that studies that find a much higher relapse rate are necessarily unaffected by nonspecific factors, as significant unblinding may occur in clinical trials. This study assessed the efficacy of synthetic anticholinergic benztropine and incidence of side-effects in 20 developmentally-disabled patients with severe drooling. The double-blind, placebo-controlled, crossover protocol included one-week baseline, two-week placebo and two-week benztropine conditions (mean dose 3.8 mg). A significant decrease in drooling during the benztropine condition relative to placebo was demonstrated and conservative response rates (calculated by deleting placebo responders), ranged up to 65 to 70 per cent. For patients completing the protocol the incidence of side-effects did not differ across conditions and minor problems such as a dry mouth were eliminated by small dose adjustments. More serious cholinergic side-effects, which resolved within 24 to 48 hours, necessitated discontinuation of the drug in three patients. This study demonstrates that synthetic anticholinergics can provide an important therapeutic alternative to surgical and behavioral therapies for drooling. Desmopressin is an approved medical therapy for the treatment of monosymptomatic primary nocturnal enuresis. In cases of limited response to desmopressin, we have added anticholinergic therapy to desmopressin (combination therapy). To evaluate this treatment strategy, we examined the efficacy of combination therapy for primary nocturnal enuresis in desmopressin-nonresponders.
                Only patients with primary nocturnal enuresis refractory to the maximal dosage of desmopressin were enrolled. Children with lower urinary tract symptoms or bowel dysfunction were excluded, on the basis of a 3-day, 24-hour, frequency-volume chart and elimination record. Children continued to take desmopressin and were assigned randomly, in a double-blind manner, to receive either extended-release anticholinergic medication or placebo. Patients were reassessed after 1 month of therapy, with a 1-week nocturnal record.
                Forty-one desmopressin-nonresponders were enrolled, and 7 patients were excluded because of noncompliance. The treatment groups were equally matched with respect to age, gender, functional bladder capacity, and number of wet nights per week. After 1 month of treatment, there was a significant reduction in the mean number of wet nights in the combination therapy group, compared with the placebo group. With a generalized estimating equation approach, there was a significant 66% decrease in the risk of a wet episode, compared with the placebo group.
                This study represents the first prospective, placebo-controlled trial examining the effect of desmopressin in combination with long-acting, anticholinergic, bladder-relaxing therapy for monosymptomatic primary nocturnal enuresis. We compared the short-term efficacy, safety and tolerability of transdermal versus oral oxybutynin in adults with urge urinary incontinence.
                Volunteers with detrusor instability currently responding to oral immediate release oxybutynin were enrolled in our study. Those patients presenting with recurrence of incontinent symptoms after a 2-week washout underwent confirmatory cystometrogram with subsequent randomization to transdermal or oral treatment. Matching active and placebo medications included matrix patches applied twice weekly and capsules taken 2 or 3 times daily. Dose titration was based on anticholinergic symptoms. Outcome measures included comparison of baseline to 6 week changes in incontinence episodes on a 3 day urinary diary, a visual analog scale for efficacy and anticholinergic symptoms reported on a questionnaire. Safety monitoring included adverse events and skin tolerability of the transdermal system.
                A total of 76 patients were enrolled and 74 completed at least 4 weeks of treatment. Mean age in the transdermal and oral groups was 64 and 63 years, and 87% and 97% were female, respectively. Daily incontinent episodes decreased in the transdermal and oral groups (7.3 to 2.4 [66%] and 7.4 to 2.6 [72%], respectively, p = 0.39). The visual analog scale reduction in urinary leakage improved from washout in both groups (p <0.0001) with no difference between them (p = 0.9). Dry mouth occurred in significantly fewer patients in the transdermal (38%) compared with those in the oral group (94%, p <0.001). Of the patients in the transdermal group 67% noticed a reduction in dry mouth severity compared with previous oral treatment, and 90% had none or mild skin erythema.
                Transdermal delivery of oxybutynin resulted in comparable efficacy and a significantly improved anticholinergic side effect profile compared with oral administration in adults with urge urinary incontinence. A multiclinic double-blind controlled study was performed on the effects of MAP in both inpatients and outpatients with AMT as control drug. 1. Subjects consisted of 41 male and 45 female patients suffering from various types of depression. MAP was assigned to 42 cases and AMT to 44 cases. Of these patients, 14 MAP cases and 10 AMT cases were subsequently dropped for a variety of reasons to obtain 28 MAP cases and 34 AMT cases as evaluable. 2. The global improvement ratings were compared and found not significantly different for any week between the two treatments. 3. The global improvement ratings by the characteristic features of patients did not show any significant difference in any items studied between the two treatments. 4. The symptomatic improvement ratings (on the Hamilton R.S. for assessment by the physician) indicated that AMT was more effective on "anxiety (psychic)." 5. The symptomatic improvement ratings (on the Beck self-assessment scale by the patient) indicated that MAP was more effective on "work" and AMT on "pathos", "feeling of satisfaction", "withdrawal" and "loss of libido." 6. During the treament period, 74.3 percent of the MAP group and 76.9 percent of the AMT group of patients showed some side effects of accompanying symptoms, with no significant difference recognized between the two treatments. Itemwise, however, the incidence of tremor was significantly lower (p-=0.06) in the MAP group. Moreover, the MAP group tended to be less liable to such anticholinergic side effects as dry mouth, constipation, trouble of accomodation, urinary disturbance and palpitation. 7. On the basis of the above findings, it is concluded that MAP is as effective against depression as AMT and less liable to the anticholinergic side effects. It is, therefore, a very useful antidepressant. To evaluate the effect of once-daily, extended-release tolterodine on urinary urgency in patients with overactive bladder.
                Patients with urinary frequency (eight or more micturitions per 24 hours) and urge incontinence (five or more episodes per week) were randomized to oral treatment with tolterodine extended release 4 mg once daily (n=398) or placebo (n=374) for 12 weeks. Efficacy was assessed by use of patient perception evaluations.
                The results presented are a secondary analysis of this double-blind, placebo-controlled study. Of patients treated with tolterodine extended release, 44% reported improved urgency symptoms (compared with 32% for placebo), and 62% reported improved bladder symptoms (placebo, 48%) (both P<.001 compared with placebo). The odds of reducing urgency and improving bladder symptoms were 1.68 and 1.78 times greater, respectively, for patients in the tolterodine extended release group than for patients receiving placebo. In response to urgency, there was a more than six-fold increase in the proportion of patients able to finish a task before voiding in the tolterodine extended release group. The proportion of patients unable to hold urine upon experiencing urgency was also decreased by 58% with tolterodine, compared with 32% with placebo (P<.001). The proportion of patients reporting "much benefit" from treatment was greater for tolterodine extended release than for placebo (43% versus 24%; P<.001). The only adverse events with an incidence of greater than 5% were dry mouth, headache, and constipation, with only dry mouth markedly more frequent with tolterodine than with placebo.
                Tolterodine extended release has demonstrable efficacy in reducing the severity of urinary urgency and is associated with improvements in overactive bladder symptoms that are meaningful to patients. The effect of the anticholinergic agent, emepronium bromide (Cetiprin), was studied in a double blind crossover study of a group of elderly patients with urinary incontinence and uninhibited bladder contractions during cystometry. There was no statistically significant difference between the subjective effect of emepronium bromide and that of placebo, and no change in the cystometric parameters. The overall subjective cure or improvement rate was 79%. The effect of anticholinergic drugs in the treatment of urinary incontinence in elderly patients with uninhibited bladder contractions might to some extent be due to an improvement in the patients' understanding and acceptance of the bladder disorders. Conservative treatment of overactive bladder employes behavioral or invasive neuromodulatory inhibition of miction reflex and administration of anticholinergic drugs.
                The aim of this study was to use non-invasive stimulation of the tibial nerve with the intention to achieve desired therapeutic effects without iatrogenic nerve damage using a superficial electrostimulation.
                All patients suffered from overactive bladder (OAB) without bladder outlet obstruction. OAB was examined by the Behavioral urge score BUS (0.0--the best and 1.0--the worst score), the International prostate symptom score IPSS (0--the best and 35--the worst score) and the Incontinence quality of life questionnaire IQOL (0.0--the worst and 1.0--the best index). The patients were divided into 3 groups: Group I--patients with electrode attached behind the medial ankle of the left lower extremity. The intensity of stimulation corresponded to 70% of the maximum amplitude of response from musculus abductor hallucis. Frequency of stimulation was 1 Hz and duration of the square impulse was 0.1 ms. Surface stimulation lasted 30 minutes and was repeated once a week. Group II--patients were treated by oral oxybutynin 5 mg t.i.d. Group III--patients without treatment. The BUS, IPSS, and IQOL were repeated after the treatment.
                The study included 28 females of average age 54 year (range 45 to 63). Mean IPSS was 17 (range 12 to 21), mean index of quality of life IQOL was 30 (range 12 to 78) and mean BUS score was 0.68 (range 0.50 to 0.86). Group I with stimulation did achieve statistically significant changes following the treatment: decrease of mean IPSS from 17 +/- 3 points to 6 +/- 4 points after the treatment, increase in mean IQOL from 36 +/- 10 to 68 +/- 20 and decrease of mean BUS from 0.65 +/- 0.12 to 0.43 +/- 0.16. Group II had similar statistically significant differences after the treatment of OAB. Group III noted no changes in the complaints.
                Noninvasive stimulation had improved subjective symptom related to overactive bladder, had no adverse events and was well tolerated. (Fig. 1, Tab. 1, Ref. 18.). We tested the role of the bladder in the pathogenesis of desmopressin resistant enuresis by evaluating the influence of urine production on the timing of the enuretic event and the response to anticholinergic medication.
                We gave 33 children with monosymptomatic nocturnal enuresis resistant to the standard 0.4 mg. oral dose of desmopressin 0.4 and 0.8 mg. desmopressin and placebo tablets for 5 nights each in a double-blind crossover fashion. The time of enuresis or nocturia was documented. All 9 children who had at least 1 dry treatment period during the randomized portion of the study then received open label treatment with 0.8 mg. desmopressin. Nonresponders to this regimen and the remainder of the children were offered anticholinergic treatment.
                Average time between bedtime and voiding was 5.0, 5.6 and 5.0 hours during the nights with placebo, and 0.4 and 0.8 mg. desmopressin, respectively (p = 0.12). Of the 9 children subsequently treated with 0.8 mg. desmopressin 5 became completely dry. Of the remaining 28 children given anticholinergic treatment 20 responded.
                Antidiuresis does not delay the enuretic event in children with desmopressin resistant enuresis. This finding and the favorable response to anticholinergic medication favor the hypothesis that these children have nocturnal bladder instability. A subgroup of enuretic children responds to high but not normal doses of desmopressin. Therapy of detrusor hyperactivity with anticholinergic agents often is followed by adverse drug reactions. Intravesical application may be an interesting alternative. A randomised, single-blind, placebo-controlled, mono-centre clinical trial was carried out in 84 patients with urgency or urge incontinence. Due to intravesical administration of oxybutynin (CAS 5633-20-5) (n = 21) and trospium chloride (CAS 10405-02-4) (n = 21), respectively, a significant increase in maximum bladder capacity and decrease of detrusor pressure accompanied by an increase of residual urine were found in comparison to placebo in urodynamical investigations. Improvement of uninhibited bladder contractions occurred leading to higher filling volume. Under verapamil (CAS 152-11-4) (n = 21) no marked changes in the efficacy variables were found compared with placebo. All patients completed the study and were assessed with regard to efficacy and safety. No adverse events or marked changes in the vital signs were reported. The immediate onset of effect and the lack of adverse drug reactions suggest that treatment with topical oxybutynin or trospium chloride is an effective alternative in patients with intolerable side effects when orally treated. In addition, intravesical administration may be indicated in patients with bladder spasms due to indwelling catheter or in order to increase bladder capacity before percutaneous cystostomy. This double-blind, multicenter study compared the efficacy and tolerability of tolterodine (Pharmacia, Los Angeles, USA) with that of oxybutynin (Alza, Palo Alto, USA) in Asian patients with overactive bladder.
                Two-hundred-and-twenty-eight adults with overactive bladder symptoms were randomized to receive tolterodine 2 mg twice daily (bid) (n = 112) or oxybutynin 5 mg bid (n = 116). After 8 weeks' treatment, changes in micturition diary variables, patients' perception of treatment benefit, and tolerability endpoints were determined.
                The mean (+/- SD) number of micturitions/24 h decreased by 2.6 +/- 2.9 (-21%) with tolterodine and 1.8 +/- 4.2 (-15%) with oxybutynin (both P = 0.0001 vs baseline). The mean number of incontinence episodes/24 h decreased by 2.2 +/- 2.3 (-85%) in the tolterodine group and by 1.4 +/- 1.8 (-58%) in the oxybutynin group (both P = 0.0001 vs baseline). Patient perception of treatment benefit was over 70% in each treatment group. Adverse events were significantly lower in the tolterodine group compared with oxybutynin-treated patients (55% vs 82%; P = 0.001). Dry mouth was reported by significantly fewer patients on tolterodine, compared with oxybutynin (35% vs 63%; P = 0.001) and withdrawals due to adverse events were lower in the tolterodine group than with those treated with oxybutynin (10% vs 16%). There were no safety concerns.
                Tolterodine 2 mg bid is equally or more effective than oxybutynin 5 mg bid in the treatment of Asian patients with overactive bladder, and shows significantly better tolerability. This may enhance compliance during long-term treatment. While the usefulness of atypical antipsychotics for improving cognitive function has been proven, the specific effects of these drugs are still unknown. The objective of this study was to investigate changes of the immediate memory and verbal working memory in patients with chronic schizophrenia after switching to one of four atypical antipsychotic agents and cessation of anticholinergic therapy. The subjects included 77 schizophrenic patients who were treated primarily with typical antipsychotics. Treatment was randomly switched to one of four atypical antipsychotics (olanzapine, perospirone, quetiapine, or risperidone) over a 4-week period, and then the drug was continued for another 4 weeks while the patient was taken off anticholinergics. The immediate memory, verbal working memory, and symptoms were evaluated. Significant improvement of immediate memory was only seen with olanzapine and risperidone. Improvement was also seen after switching to perospirone, but immediate memory worsened after treatment with this anticholinergic drug was discontinued. Deterioration was seen after switching to quetiapine, but immediate memory improved and reached the previous level after treatment with anticholinergic drugs was discontinued. Significant improvement of the verbal working memory was only seen during risperidone administration. The findings suggested that switching chronic schizophrenic patients to atypical antipsychotics can improve both the immediate memory and the verbal working memory when risperidone is used, while improvement of immediate memory can be expected with olanzapine. From the viewpoint of improving the memory, quetiapine should not be administered concomitantly with anticholinergic drugs, and caution should be exercised when discontinuing anticholinergic drugs during treatment with perospirone. Anticholinergics are commonly used for the treatment of frequency, urgency, and urge incontinence in women. Alpha-blockers have been shown to have a modulating effect on bladder smooth muscle but are not commonly used clinically for this indication. To evaluate the clinical effectiveness of each treatment as well as the combination therapy, we performed an open prospective study comparing these agents. Between September 1994 and October 1995, 34 women aged 28-91 (mean age, 62) received either 0.375 mg of sustained-release hyoscyamine twice a day or 2 mg doxazosin QHS prior to being crossed over to the other drug and/or the combination. Symptoms were assessed using an expanded American Urological Association (AUA) symptoms score, which included questions regarding incontinence at completion of each therapeutic phase. Evaluation included 6-channel urodynamics. All three therapies were noted to be effective in reducing AUA symptom scores. By urodynamic evaluation, a greater percentage of patients with increased voiding pressures or decreased compliance responded to doxazosin than hyoscyamine. Side effects were noted to be less prevalent with doxazosin than with the other therapies. There appears to be a significant role for alpha-blockers in the treatment of voiding symptoms in women. Approximately 30 percent of patients undergoing anorectal surgery will develop acute urinary retention. The cause of this complication is poorly understood. Anxiety, anal distention, bladder distention as a result of vigorous hydration during surgery, and reflex inhibition of the urinary bladder detrusor muscle secondary to pain have been postulated as contributing factors. A four-armed prospective, double-blind, randomized trial was carried out to determine whether an anxiolytic agent (midazolam, 5 mg intramuscularly) and/or a parasympathomimetic agent (bethanechol, 10 mg subcutaneously) reduce the incidence of postoperative urinary retention following anorectal surgery. One hundred thirty-two patients (ages, 18 to 50 years), in acute urinary retention 6 to 12 hours following anorectal surgery, were enrolled. Sixty-nine percent of patients responded to bethanechol. Side effects were minimal. Midazolam alone had no effect on retention. Bethanechol and midazolam in combination resulted in less retention than midazolam and a placebo (P less than 0.05). Bethanechol alone was better than a placebo (P less than 0.002). Mean intraoperative intravenous fluid volume for the entire study group was 900 cc. Initial postoperative urinary volumes of patients who failed the treatment protocol were significantly higher than in those responding to bethanechol (mean of 527 cc vs. 241 cc, P less than 0.001). The use of an anxiolytic agent was not effective in the treatment of postoperative urinary retention. Bladder distention may increase the incidence of urinary retention. Bethanechol, in a dose of 10 mg subcutaneously, significantly lowered the incidence of postoperative urinary catheterization and should be considered as initial treatment of postoperative urinary retention following anorectal surgery. To investigate and compare the effectiveness of various treatment protocols for the treatment of women with idiopathic detrusor overactivity.
                Prospective, randomized controlled trial.
                Departments of Physiotherapy and Rehabilitation and Obstetrics and Gynaecology, Hacettepe University.
                Forty-six subjects were randomized to three groups.
                The first group received only pharmacotherapy, the second group received only physiotherapy and in the third group pharmacotherapy was combined with physiotherapy (combined therapy group).
                All patients were evaluated at the beginning and at the end of treatment. Assessment parameters were maximum cystometric capacity, electromyographic activity of pelvic floor muscles, voiding diary parameters, the amount of urine leakage and the quality of life score.
                The maximum cystometric capacity and the electromyographic activity of pelvic floor muscles increased significantly and the number of voids/day and incontinence episodes/day, and the amount of urine leakage reduced significantly (P < 0.05) in both physiotherapy and combined therapy groups while there was no significant difference in the pharmacotherapy group. After treatment, the number of voids/day increased by 0.3 ± 3.4 in the pharmacotherapy group (P > 0.05) and decreased by 5.1 ± 5.5 and 4.7 ± 5.6 in the physiotherapy and combined therapy groups, respectively (P < 0.05). Statistically significant improvements were observed in all groups according to the number of voids/night and the quality of life scores at the end of the treatment.
                The physiotherapy protocol we introduced in the present study with or without anticholinergic therapy has a substantial positive impact on the treatment of female patients with idiopathic detrusor overactivity. Application of physostigmine to the oromucosal surface with the aim of stimulating underlying mucin-producing glands while reducing cholinergic systemic effects might be a strategy for treating dry mouth. Subjects suffering from dry mouth and with hyposalivation participated in a crossover, double-blind, randomized study. A gel containing physostigmine (0.9, 1.8, 3.6, and 7.2 mg) or placebo was applied to the inside of the lips and distributed with the tongue. The feeling of dryness was assessed using a visual analogue scale (VAS) (where a score of 100 = extremely dry) and systemic effects were registered. Based on assessments of efficacy and safety, the dose of 1.8 mg of physostigmine was selected for use in the second part of the study to make objective measurements of saliva volumes. Physostigmine (1.8 mg) produced long-lasting (120 min) relief (evident as a score reduction of 25 on the VAS) in the feeling of dryness. Judging from AUC values related to baseline over 180 min, the improvement for both mouth and lips in response to physostigmine was six times greater than that to placebo. At higher doses of physostigmine, gastrointestinal discomfort predominantly occurred. The volume of saliva collected in response to physostigmine was five times higher over 180 min than that collected in response to placebo. Physostigmine, applied locally, therefore appears to be a promising modality for dry-mouth treatment. A central anticholinergic syndrome (CAS) can be related to the majority of anesthetic agents, but is often not recognized as such. Thus, most anesthesiologists seem to miss the occurrence of an anticholinergic syndrome especially when agitation and/or restlessness are the major symptoms. Therefore, the following study was undertaken to test the hypothesis that routine administration of the anticholinergic agent physostigmin is of benefit for patients in regard to vigilance, the cardiovascular system and the need of analgesics easing the time in the post anesthesia care unit (PACU).
                After approval by the local ethics committee and written informed consent, 100 patients undergoing a cholecystectomy or a struma resection, were given either physostigmin (n = 51) or saline 0.9 % (n = 49) in a randomized fashion. The study was conceived to block a possible isoflurane-N2O/O2 (opioid-based plus relaxant) induced central anticholinergic syndrome and to evaluate the effects on the cardiovascular system on vigilance and on postoperative analgesic demand. Following parameters were measured: systolic and diastolic blood pressure, heart rate, respiratory rate, and arterial blood gases. In addition, vigilance was determined and typical anticholinergic symptoms (disorientation, slurred speech, agitation, nausea, emesis, cardiac arrhythmia and muscle shivering) were determined 10, 20, 40 and 60 minutes following the intravenous injection of physostigmin. Also, the need for the postoperative analgesic pethidine was evaluated among the two groups.
                Except for a significant reduction in the need of analgesics, a reduced diastolic pressure and heart rate and a lower incidence of muscle shivering there was no difference among the two groups. One major side effect following the use of physostigmin was the higher incidence of nausea in the im mediate minutes following injection. This effect may be due to the rapid injection of the anticholinergic compound. Otherwise there were no detrimental effects of physostigmin in patients.
                From the results it can be concluded that routine administration of an anticholinergic agent results in a short term beneficial effect in regard to vigilance, a lesser incidence of muscle shivering and a lesser demand for analgesics. However, because of the low incidence of a classical central anticholinergic syndrome, routine physostigmine is only indicated when agitation is diagnosed. Prominent and persistent anxiety, depression, and/or negative features characterize a substantial minority of recovered or residually psychotic schizophrenic outpatients and contribute to poor outcome. Because extrapyramidal side effects of typical neuroleptic medications often resemble such features, we first systematically studied the contribution of extrapyramidal side effects to these problems and their treatment. For patients who remained distressed, controlled trials of supplemental thymoleptics were undertaken.
                In trial 1, 92 distressed (depressed and/or anxious) patients and 36 patients in a defect state (patients with negative symptoms) participated in a double-blind, intramuscular challenge that compared centrally acting benztropine mesylate with peripherally acting glycopyrrolate. In trial 2, 57 distressed patients and 22 patients in a defect state were randomly assigned to a double-blind, neuroleptic medication dose-reduction group. In trial 3, 57 chronically distressed patients who were maintained on a low dose of fluphenazine decanoate were randomly assigned to a supplemental desipramine hydrochloride, lithium carbonate, or placebo group under double-blind conditions for 12 weeks.
                For patients who were already maintained on antiparkinsonian medication, impaired affect was not resolved by additional benztropine. Only distressed patients with a family history of severe mental disorder (often affective) showed improvement with neuroleptic medication dose reduction. Patients in the defect-state group reported less dysphoria on a reduced neuroleptic medication dose, but negative symptoms persisted. Desipramine improved diverse aspects of mood and residual psychoticism, possibly as a prophylaxis against minor affective exacerbations. Depression improved in women only. Lithium positively affected multiple indexes of anxiety and anxious depression.
                Most often, persistent affective impairments are neither resistant extrapyramidal side effects nor characterological traits. Thymoleptics improve the nonphasic, chronic types of anxiety and depression in contrast to the acute, episodic forms, for which little support can be found in the literature. Treatment with the antimuscarinic agents tolterodine and oxybutynin is the mainstay of therapy for overactive bladder, a chronic and debilitating condition characterized by urinary urgency with or without urge incontinence, usually in combination with urinary frequency and nocturia. This study consisted of two trials; in one, patients with overactive bladder were randomized to 8 weeks of open-label treatment with either 2 mg or 4 mg of once-daily extended-release tolterodine (TER), and in the other to 5 mg or 10 mg of extended-release oxybutynin (OER). The study protocol and design were identical for the two trials and site selection ensured that there was no bias in either trial for the tendency of investigators to prescribe one drug rather than the other, or for geographical location. A total of 1289 patients were enrolled, 669 in the tolterodine trial (TER 2 mg, n = 333; TER 4 mg, n = 336) and 620 in the oxybutynin trial (OER 5 mg, n = 313; OER 10 mg, n = 307). Fewer patients prematurely withdrew from the trial in the TER 4 mg group (12%) than either the OER 5 mg (19%; p = 0.01) or OER 10 mg groups (21%; p = 0.002). More patients in the OER 10 mg group than the TER 4 mg group withdrew because of poor tolerability (13% vs 6%; p = 0.001). After 8 weeks, 70% of patients in the TER 4 mg group perceived an improved bladder condition, compared with 60% in the TER 2 mg group, 59% in the OER 5 mg group and 60% in the OER 10 mg group (all p < 0.01 vs TER 4 mg). Response to therapy was greater in a subgroup of patients whose perception of bladder condition was moderate to severe at baseline (TER 4 mg 77% vs OER 10 mg 65%; p < 0.01). Dry mouth was dose-dependent with both agents, although differences between doses only reached statistical significance in the oxybutynin trial (OER 5 mg vs OER 10 mg; p = 0.05). Patients treated with TER 4 mg reported a significantly lower severity of dry mouth compared with OER 10 mg. In conclusion, the greater efficacy and tolerability of tolterodine ER 4 mg suggests improved clinical effectiveness compared with oxybutynin ER 10 mg. To compare the effects of trospium hydrochloride and electrical stimulation on urodynamic parameters, bladder diary, quality of life and psychological symptoms in female patients with overactive bladder syndrome.
                Prospective, randomized controlled trial.
                Department of Physical Medicine and Rehabilitation, University Hospital.
                Thirty-five patients were divided into either trospium chloride (Group 1) or intravaginal electrical stimulation therapy (Group 2).
                All patients were assessed at the beginning of the treatment, at weeks 6 (end of treatment), 10 and 18 according to urodynamic parameters, voiding diary parameters, severity of urgency (visual analogue scale, VAS), the Incontinence Impact Questionnaire Short Form (IIQ-7), and the Beck Depression Inventory.
                Statistically significant improvements were observed in both groups according to some urodynamic parameters, voiding diary parameters, VAS urgency severity, Incontinence Impact Questionnaire Short Form and Beck Depression Inventory scores at the end of the treatment (P<0.05). During the 18-week follow-up period, deteriorations were observed in many parameters in both groups although improvements in the frequency of urgency, the frequency of incontinence episodes, VAS urgency severity, and Beck Depression Inventory score in Group 2 persisted (P<0.05). Significant differences were not detected between groups at the end of the treatment or during the posttreatment follow-up controls (P>0.05).
                No difference was detected between trospium hydrochloride and intravaginal electrical stimulation in the treatment of female overactive bladder syndrome. Discontinuation of both treatments caused deterioration in most of the objective and subjective symptoms of overactive bladder syndrome. Although antimuscarinic treatment is indicated for overactive bladder, many patients discontinue it because of dry mouth. Of available antimuscarinics oxybutynin is associated with the highest dry mouth rate. We compared the safety and tolerability of 5 mg solifenacin vs 15 mg oxybutynin immediate release.
                At 12 Canadian centers a total of 132 patients with overactive bladder symptoms (greater than 1 urgency episode per 24 hours, and 8 or greater micturitions per 24 hours) were randomized to 5 mg solifenacin once daily or 5 mg oxybutynin 3 times daily for 8 weeks. The primary end point was the incidence and severity of dry mouth reported after direct questioning. Efficacy end points (3-day diary documented changes in urgency, frequency, incontinence, nocturia and voided volume), and changes on the Patient Perception of Bladder Condition scale and the Overactive Bladder Questionnaire were evaluated secondarily.
                Of patients on solifenacin vs oxybutynin immediate release 35% vs 83% reported dry mouth (p <0.0001). Of patients reporting dry mouth severity was graded moderate by 13% and 42% of those on solifenacin and oxybutynin immediate release, and severe by 13% and 28%, respectively (p = 0.001). Patients in each group showed improvements in efficacy end points, and Patient Perception of Bladder Condition scale and Overactive Bladder Questionnaire scores from baseline to treatment end.
                Significantly fewer patients on 5 mg solifenacin once daily reported dry mouth vs those receiving 5 mg oxybutynin immediate release 3 times daily. Significantly fewer patients on solifenacin reported moderate/severe dry mouth. Significantly fewer patients on solifenacin withdrew from study due to dry mouth and there were significantly fewer overall adverse events. Solifenacin and oxybutynin immediate release were efficacious in decreasing efficacy end points, and improved Patient Perception of Bladder Condition scale and Overactive Bladder Questionnaire results from baseline to treatment end.

This trial was designed to investigate the effectiveness of extended release versus immediate release oxybutynin in reducing symptoms of overactive bladder in a community-dwelling female population over the age of 65.
                This was a prospective randomized 12-week, open-label study. The primary outcome was number of micturitions per 24 hours, 12 weeks after treatment. The a priori sample size estimate was 60 patients per group.
                Of the 318 women approached, only 72 women (23%) were enrolled over 34 months (33 in the immediate release group, and 39 in the extended release group). The study was stopped prematurely because of recruitment difficulties and an interim analysis revealing the need for a much larger sample than had been estimated to show a significant difference between treatments. After 12 weeks of treatment, there was no difference between the oxybutynin extended release and immediate release groups in the number of micturitions per 24 hours or in other outcomes.
                This study did not demonstrate differences between oxybutynin extended release and immediate release and in reducing symptoms of overactive bladder or quality of life, possibly because the study did not reach the necessary sample size. The difficulty in recruiting subjects for the trial likely resulted from the onerous study requirements (4 study visits required over 12 weeks) and the downtown location of the study centres: these factors would cause particular difficulties for women over age 65 with overactive bladder, for whom travelling may be a problem. Evidence is needed to guide prescribing for older patients, but designing research to obtain adequate sample sizes is difficult. Studies in older subjects should ensure that a much larger budget is allocated for recruitment than would be allocated for studies in younger subjects, that meticulous attention is paid to issues of transport and access, and that support is provided for subjects who agree to take part research. To explore the effect on sleep/wake activity and on behavioral and psychological symptoms of the withdrawal of antipsychotic medications from nursing home (NH) patients with dementia.
                Randomized, placebo-controlled, double-blind trial.
                NHs in Bergen, Norway.
                Thirty patients (mean age 83.5) taking haloperidol, risperidone, or olanzapine for nonpsychotic symptoms. Intervention: Study participants were randomly assigned to withdrawal (intervention group) or continued treatment with antipsychotic medications (reference group) for 4 consecutive weeks.
                Behavioral rating using the Neuropsychiatric Inventory Questionnaire (NPI-Q) and actigraphy.
                After antipsychotic withdrawal, behavioral scores remained stable or improved in 11 of 15 patients, whereas four had worsening scores. Actigraphy revealed decreased sleep efficiency after drug discontinuation and increased 24-hour and night activity in both groups. Actigraphy records of nighttime and daytime activity indicated sleep problems and restlessness, in terms of the NPI-Q. One patient was restarted on antipsychotics.
                Antipsychotic drug withdrawal affected activity and sleep efficiency over the short term. Increases in total activity and impaired sleep quality after drug discontinuation should be monitored, because the long-term effect of these changes is not known. The NPI-Q and actigraphy are feasible tools that disclose relevant changes occurring during antipsychotic withdrawal in NH patients with dementia. Their use in clinical practice should be substantiated by larger studies. To compare the efficacy and safety of controlled-release oxybutynin with conventional, immediate-release oxybutynin and determine rates of dry mouth.
                Patients (n = 226) who were known to be responsive to anticholinergic therapy and who had seven or more urge incontinence episodes per week were randomized to receive controlled-release oxybutynin or immediate-release oxybutynin. After an initial placebo run-in period, dosing in each began at 5 mg per day and increased weekly by 5 mg per day to a maximum of 20 mg per day or when a balance between improvement of incontinence symptoms and tolerability of side effects was achieved. Rates of urge incontinence and dry mouth were compared. Post hoc Kaplan-Meier survival analysis was used to describe elimination of incontinence episodes by dose and to analyze dry mouth risk by dose.
                Reductions in urge urinary incontinence episodes from baseline to the end of treatment were 18.6 to 2.9 per week (83% mean decrease) and 19.8 to 4.4 per week (76% mean decrease) in the controlled- and immediate-release oxybutynin groups (P =.36), respectively. At equal doses, comparable proportions of patients in both groups reported the absence of urge incontinence (P =.85). The incidence of dry mouth increased with dose in both groups, but there was no difference in dry mouth rates between the groups: 47.7% and 59.1% for the controlled- and immediate-release oxybutynin (P =.09), respectively. However, Kaplan-Meier analysis to examine first report of dry mouth at a given dose revealed that a significantly lower proportion of patients taking controlled-release oxybutynin had moderate to severe dry mouth (P =.007) or any dry mouth (P =.003) compared with those taking immediate-release oxybutynin.
                At the same daily dose, controlled- and immediate-release oxybutynin demonstrated comparable efficacy in reduction of urge incontinence episodes. The incidence of dry mouth was dose dependent but equal in both groups; first report of moderate to severe dry mouth was significantly lower in the controlled-release group. Eighteen patients with irritable colon syndrome were treated with a new anticholinergic drug (prifinium bromide) and with a placebo in a 6-wk, randomized, double-blind cross-over study. The drug was orally administered in a daily dose of 90 mg before meals. Three manifestations (pain, flatulence, constipation, and/or diarrhea), scored weekly, were used as assessment criteria. Mean over-all ratings showed a difference in favor of the drug, and were statistically significant. Side effects were rare and mild. We have come to the conclusion that this anticholinergic drug may be of benefit to patients with pain-predominant forms of irritable colon syndrome. Women with urge urinary incontinence are commonly treated with antimuscarinic medications, but many discontinue therapy.
                To determine whether combining antimuscarinic drug therapy with supervised behavioral training, compared with drug therapy alone, improves the ability of women with urge incontinence to achieve clinically important reductions in incontinence episodes and to sustain these improvements after discontinuing drug therapy.
                2-stage, multicenter, randomized clinical trial conducted from July 2004 to January 2006.
                9 university-affiliated outpatient clinics.
                307 women with urge-predominant incontinence.
                10 weeks of open-label, extended-release tolterodine alone (n = 153) or combined with behavioral training (n = 154), followed by discontinuation of therapy and follow-up at 8 months.
                The primary outcome, measured at 8 months, was no receipt of drugs or other therapy for urge incontinence and a 70% or greater reduction in frequency of incontinence episodes. Secondary outcomes were reduction in incontinence, self-reported satisfaction and improvement, and scores on validated questionnaires measuring symptom distress and bother and health-related quality of life. Study staff who performed outcome evaluations, but not participants and interventionists, were blinded to group assignment.
                237 participants completed the trial. According to life-table estimates, the rate of successful discontinuation of therapy at 8 months was the same in the combination therapy and drug therapy alone groups (41% in both groups; difference, 0 percentage points [95% CI, -12 to 12 percentage points]). A higher proportion of participants who received combination therapy than drug therapy alone achieved a 70% or greater reduction in incontinence at 10 weeks (69% vs. 58%; difference, 11 percentage points [CI, -0.3 to 22.1 percentage points]). Combination therapy yielded better outcomes over time on the Urogenital Distress Inventory and the Overactive Bladder Questionnaire (both P <0.001) at both time points for patient satisfaction and perceived improvement but not health-related quality of life. Adverse events were uncommon (12 events in 6 participants [3 in each group]).
                Behavioral therapy components (daily bladder diary and recommendations for fluid management) in the group receiving drug therapy alone may have attenuated between-group differences. Assigned treatment was completed by 68% of participants, whereas 8-month outcome status was assessed on 77%.
                The addition of behavioral training to drug therapy may reduce incontinence frequency during active treatment but does not improve the ability to discontinue drug therapy and maintain improvement in urinary incontinence. Combination therapy has a beneficial effect on patient satisfaction, perceived improvement, and reduction of other bladder symptoms. Two hundred forty-one elderly depressed patients entered the 8-week, double-blind phase of this parallel-group, multicenter study; 161 patients were randomized to receive sertraline (50-200 mg/day) and 80 were randomized to receive amitriptyline (50-150 mg/day). Among evaluable patients, there were no statistically significant differences between treatments in any of the primary efficacy variables: change in total Hamilton Rating Scale for Depression (HAM-D) score (17 items), percentage change in HAM-D score, change in HAM-D Item 1, change in Clinical Global Impressions (CGI) Severity score, change in the Depression Factor of the 56-item Hopkins Symptom Checklist, and the CGI Improvement score at the last visit. Similar results were obtained using data from all patients (intention-to-treat analysis), except that amitriptyline was superior in HAM-D Total score (p = .044). The two drugs produced a similar degree of response: on the basis of the HAM-D criterion, 69.4% of sertraline patients and 62.5% of amitriptyline patients responded, and, on the basis of CGI criterion, 79.5% of sertraline and 73.4% of amitriptyline patients responded. Twenty-eight percent of the sertraline patients withdrew from the study because of a treatment-related side effect and 2.5% (4) because of a laboratory abnormality. In comparison, 35% of the amitriptyline patients withdrew because of treatment-related side effects. Sertraline was associated with a statistically lower frequency of somnolence, dry mouth, constipation, ataxia, and pain and a higher frequency of nausea, anorexia, diarrhea/loose stools, and insomnia; thus, anticholinergic effects were less common and gastrointestinal effects were more common with sertraline than with amitriptyline.(ABSTRACT TRUNCATED AT 250 WORDS) Amisulpride is a potent substituted benzamide antipsychotic drug claimed to improve the negative symptoms of schizophrenia, particularly at low dosage.
                Sixty long-term in-patients with schizophrenia and selected for predominant negative symptoms were randomised to receive either haloperidol or amisulpride. Over a year there was systematic dose reduction, as symptoms allowed.
                There were no significant differences between the treatment groups in the proportion receiving low-dose treatment, the control of positive symptoms, or ratings of social behaviour, side-effects or tardive dyskinesia. For negative symptoms, there were consistent but non-significant trends in favour of amisulpride. The amisulpride patients required significantly less anticholinergic medication.
                In chronically-hospitalised in-patients with schizophrenia characterised by persistent negative symptoms, amisulpride was a well-tolerated maintenance antipsychotic medication. The drug had only a limited effect in reducing negative symptoms, which were relatively stable, enduring phenomena in this sample, despite dosage reduction. To evaluate the outcome of surgery for stress urinary incontinence (SUI) in patients presenting with a combination of stress and sensory urge UI.
                The study comprised 75 women presenting with mixed incontinence; the most important inclusion criterion was a negative cystometrogram for detrusor overactivity. Based on random selection, a third of the patients received a 6-month course of anticholinergic treatment (group 1) and 50 (group 2) had surgery for SUI. The surgical procedure depended on the Valsalva leak-point pressure (VLPP); those with a VLPP of > or = 90 cmH2O underwent Burch retropubic bladder neck suspension (group 2a, 24 patients) while 26 (group 2b) with a VLPP of < 90 cmH2O had pubovaginal sling (PVS) surgery. A further group of 20 patients with pure SUI (no urge UI) underwent surgery (PVS in 12 and Burch in eight) as a control group (group 3). After at least 6 months of follow-up (mean 9.3, sd 1.7), 68 patients were evaluable; they were assessed subjectively and objectively for dryness, and by a urodynamic evaluation and quantitative assessment using the SEAPI scoring system.
                In group 1 none of the patients became completely dry; there was persistent stress with and without urge UI in nine (43%) and 12 (57%) of the available 21 patients, respectively. Only three of those who had persistent SUI with no urge in the whole study group were satisfied and chose to continue anticholinergic therapy despite SUI. In this group the mean (sd) improvement in the subjective and objective SEAPI score was 3.4 (1.0) and 2.3 (3.8), respectively. In group 2a, 20 of the available 23 patients (87%) became completely dry (both stress and urge continent). The mean improvement in the SEAPI scores was 7.8 (0.9) and 7.8 (1.3), respectively. In group 2b, 20 of the 24 patients (83%) became completely dry, with mean improvements in SEAPI scores of 8.2 (0.4) and 7.9 (0.3), respectively. The improvement was statistically significant after surgery, vs anticholinergic therapy, for all variables (P < 0.05). The incidence of persistent urge UI was highest in group 1 (43%), being 13% in group 2 (13% and 12% in 2a and b, respectively). In group 3 there was de novo urge UI in four of the 20 patients, and not significantly different from that in group 2.
                Most patients with mixed stress and urge UI and a normal cystometrogram were cured of both symptoms by surgery. The incidence of residual urge in such patients was no higher than that of de novo urge after surgery in patients with genuine SUI. 34 patients suffering from detrusor hyperreflexia due to multiple sclerosis entered the trial and 32 patients accomplished. The patients received each drug for a period of 14 days. The patients made records of relevant symptoms, urgency and urge incontinence and compared the treatment periods according to these symptoms. Registration of the number of micturitions was also made. Furthermore, the patients underwent cystometric studies. The following parameters were recorded and compared: residual urine, volume at the first bladder contraction, effective volume and amplitude of the first bladder contraction. The study showed that the patients preferred methantheline bromide. The entire cystometric pattern changed statistically significant with methantheline bromide, but only with concordance to the patients preferences in 60%. Decrease in number of micturitions and volume at the first bladder contraction were the only parameters showing accordance with the preferences. The drugs caused many various side effects. 12 treatment periods were discontinued due to side effects of meladrazine tartrate. The cystometric recordings seem to be of little use in evaluation of a drugs therapeutic effect, and it is difficult to find parameters which reflect the patients preference of the drugs. We compared the effects of bladder training and/or tolterodine as first line treatment in female patients with overactive bladder (OAB). One hundred and thirty-nine female patients with OAB were randomized to treatment with bladder training (BT), tolterodine (To, 2 mg twice daily) or both (Co) for 12 weeks. Treatment efficacy was measured by micturition diary, urgency scores and patients' subjective assessment of their bladder condition. Mean frequency and nocturia significantly decreased in all treatment groups, declining 25.9% and 56.1%, respectively, in the BT group; 30.2% and 65.4%, respectively, in the To group; and 33.5% and 66.3%, respectively in the Co group (p<0.05 for each). The decrease in frequency was significantly greater in the Co group than in the BT group (p<0.05). Mean urgency score decreased by 44.8%, 62.2% and 60.2% in the BT, To, and Co groups, respectively, and the improvement was significantly greater in the To and Co groups than in the BT group (p<0.05 for each). Although BT, To and their combination were all effective in controlling OAB symptoms, combination therapy was more effective than either method alone. Tolterodine alone may be instituted as a first-line therapy, but may be more effective when combined with bladder training. The effect of cognitive therapy (CT) on resistant burning mouth syndrome (BMS) was studied. Thirty patients with resistant BMS after odontological and medical treatment were randomly divided into two equal groups; a therapy group (TG) was treated with CT and an attention/placebo group (APG) served as a control group. The intensity of BMS, which was estimated by the use of a visual analogue scale, was significantly reduced in the TG directly after CT was completed and was further reduced in a 6-month follow-up. The APG did not show any decrease in intensity of BMS. The results of this study indicate that, in some cases, resistant BMS probably is of psychological origin. Xerostomia is a subjective sensation of mouth dryness often occurring as an unwanted effect of psychotropic drugs.
                The clinical efficacy and acceptability of a new oxygenated glycerol triester (OGT) oral spray (1 or 2 sprays up to 4 times daily) in the treatment of xerostomia was compared with those of a commercially available artificial saliva substitute (ASS [Saliveze]) in a 2-week, open-labeled, randomized, parallel-group study. Clinical assessment of xerostomia included evaluation of mouth dryness by means of a 10-cm-long visual analog scale, objective blinded assessment of the oral tissue condition by a dental hygienist by means of a 4-point ordinal scale, and subjective patient-based assessment of dry mouth symptoms by means of dichotomous responses to a questionnaire. [Day 14 - baseline] patient-based mouth dryness score was the primary end point.
                Seventy-four patients (41 women and 33 men, 44 +/- 15 years) undergoing long-term psychotropic drug treatment were consecutively enrolled. At day 14, OGT resulted in better efficacy than ASS in mouth dryness score (mean difference, 1.2 +/- 0.4; P = 0.006), speech difficulties (mean difference, 1.2 +/- 0.4; P = 0.005), taste (mean difference, 1.1 +/- 0.4; P = 0.02), and overall mouth condition (mean difference, 1.4 +/- 0.9; P = 0.005). Taste of OGT was better than that of ASS (mean difference, 1.4 +/- 0.6; P = 0.04), as was OGT acceptability (mean difference, 1.4 +/- 0.9; P = 0.005).
                Oxygenated glycerol triester lubricant oral spray was superior to a commercially available ASS in improving xerostomia and overall condition of the oral tissue. 21 depressed patients of the Basle University Psychiatric Outpatient Clinic were treated in a double-blind study with paroxetine and amitriptyline. 11 of these patients did not continue the trial until the end of the 7th week. There was a significant difference in the number of dropouts between the two groups: 80% of the amitriptyline group did not continue until the end, while in the paroxetine group we found only 30% dropouts. The patients of both groups showed a gradual decrease of the median total scores on the Hamilton and the Montgomery and Asberg Depression Rating Scales. Although the number of patients who stayed in the trial for at least 4 weeks (8 with paroxetine, 6 with amitriptyline) is quite small, we see from the results of the clinical global impression that the members of the paroxetine group improved most of all in the somatic symptoms, while considering their moods we found no differences between the groups. Patients of both groups complained about side effects, most of all about dry mouth and tiredness. From the high rate of dropouts under amitriptyline we found that the side effects under this drug were more severe and therefore led to the dropouts. Objective To compare the tolerability and clinical efficacy of tolterodine and oxybutynin in the treatment of Hong Kong Chinese women with an overactive bladder. Patients and methods A randomized controlled trial was conducted at two urogynaecology centres in Hong Kong. In all, 106 women with urodynamically confirmed detrusor instability were recruited. Baseline severity assessments included a visual analogue scale (VAS), urinary diary and urinary pad-test. The women were randomized to receive either oral tolterodine 2 mg or oxybutynin 5 mg twice daily for 10 weeks. Treatment responses were assessed at 4 and 10 weeks using the VAS and urinary diary. Treatment tolerability was assessed at baseline, 4 and 10 weeks using the Xerostomia Questionnaire. A urinary pad-test was repeated at 10 weeks. Results The perceived change from baseline VAS was better in the tolterodine than the oxybutynin group after 10 weeks of treatment (per-protocol analysis, P = 0.043). The two drugs were effective in reducing the symptoms of frequency (P < 0.001). Tolterodine was significantly better than oxybutynin in reducing urinary leakage (urinary pad-test; median change - 5.00 g vs 0 g, P = 0.019). Both drugs caused a significant worsening of dry mouth (overall dryness, P < 0.005; discomfort, P < 0.005; sleep, P = 0.021; speaking, P = 0.045; swallowing, P = 0.004; and liquid consumption, P = 0.017). Conclusions Both oxybutynin and tolterodine were effective in ameliorating the severity of the symptoms of detrusor instability. Tolterodine was better than oxybutynin in both subjective and objective outcome measures, but both drugs caused similar worsening of dry mouth that may limit the tolerability of these medications. The aim of this study was to compare the efficacy and safety of alpha1-adrenoceptor (alpha1-AR) antagonist monotherapy with combination therapy using alpha1-AR antagonist and anticholinergic agent for benign prostatic hyperplasia (BPH) with storage symptoms as the chief complaint.
                In this prospective comparative study, either 25-75 mg/day of naftopidil monotherapy (monotherapy group) or combination therapy using 25-75 mg/day of naftopidil and an anticholinergic agent (10-20 mg/day of propiverine hydrochloride or 2-6 mg/day of oxybutynin hydrochloride; cotherapy group) were administered for 12 weeks to 101 BPH patients with storage symptoms.
                International prostate symptom score (IPSS) and quality of life (QOL) index improved significantly in both groups, with no marked differences between groups. Maximum flow rate (Qmax) and residual urine volume (RUV) tended to improve in both groups, again with no marked differences between groups. However, median post-therapeutic RUV was significantly worse for the cotherapy group (45.0 mL) than for the monotherapy group (13.5 mL; P = 0.0210). Ratio of patients with increased RUV was also significantly worse for cotherapy (22.9%) than for monotherapy (5.0%; P = 0.038).
                Although the anticholinergic dosage was low, the present results suggest that naftopidil monotherapy was as useful as combination therapy of naftopidil and an anticholinergic agent. Therefore, naftopidil is a useful agent as the first choice in BPH patients with storage symptoms. OBJECTIVE To determine whether botulinum toxin-A (BTX-A) treatment has an effect on the quality of life (QoL) of patients with overactive bladder (OAB) refractory to anticholinergics. PATIENTS AND METHODS This was a single centre, randomized, double-blind, placebo-controlled trial. Participants were men and women with idiopathic detrusor overactivity (IDO). Participants were randomised to receive either 200 U of BTX-A (Botox(R), Allergan Inc., Irvine, CA, USA; n = 16) or placebo (n = 18) via a trigone-sparing flexible cystoscopic technique. QoL was assessed using the King's Health Questionnaire (KHQ) at baseline and at 4 and 12 weeks, after injection. At 12 weeks patients were 'unblinded' and a further open-label follow-up in the BTX-A group occurred at 24 weeks. The changes in the subdomains of the KHQ were assessed over the study period. RESULTS Overall QoL was significantly improved in the BTX-A treated patients compared with placebo in the blinded part of the study. When analysing the KHQ subdomains, 'Incontinence Impact', 'Emotions', 'Physical Limitations', 'Social Limitations' and 'Severity Measures' were significantly improved in those that received BTX-A compared with placebo. The 'Symptom Severity' domain was also significantly improved at 4 weeks but not at 12 weeks. At 12 weeks 'Role Limitations' also became statistically significant in favour of BTX-A. The open-label extension study suggested these benefits last for at least 24 weeks. CONCLUSIONS BTX-A bladder injections at 200 U appear to improve QoL in patients with OAB symptoms and IDO refractory to anticholinergics for at least 24 weeks. As well as the improvement seen in clinical parameters with this form of therapy, perhaps of more importance to the patient, is the improvement in QoL. To evaluate the efficacy, safety/tolerability, and dose-response relationship of imidafenacin in Japanese patients with overactive bladder.
                Men and women who had overactive bladder symptoms were randomized equally to double-blind treatment with 0.05, 0.1, or 0.25 mg of imidafenacin twice daily or a placebo for 12 weeks, and assessed for efficacy and safety.
                Overall, 401 patients were enrolled and randomized for treatment with 0.1 mg of imidafenacin/day (99 patients), 0.2 mg of imidafenacin/day (100), 0.5 mg of imidafenacin/day (101), or a placebo (101). After 12 weeks of treatment, the number of incontinence episodes was reduced in a dose-dependent manner, and a significant difference between the imidafenacin treatment and the placebo was observed (P < 0.0001). Compared with the placebo, imidafenacin caused significant reductions in urgency incontinence, voiding frequency, and urinary urgency, and a significant increase in the urine volume voided per micturition. Imidafenacin was also well tolerated. The incidence of dry mouth in the imidafenacin groups increased dose-dependently. Even though the percentage of patients receiving 0.5 mg/day who discontinued treatment due to dry mouth was high (8.9%), the percentages in the 0.1 mg/day and 0.2 mg/day groups (1.0% and 0.0%, respectively) were comparable with that in the placebo group (0.0%).
                Considering the balance between efficacy and safety, 0.1 mg of imidafenacin twice daily appeared to be a clinically appropriate dose for treating overactive bladder. This dose was therefore selected for further evaluation in large-scale phase III studies. A stratified, randomised, waitlist controlled study over 12 months assessed the effectiveness of a 6 week bladder rehabilitation programme in persons with multiple sclerosis (pwMS) in an Australian community cohort.
                Patients with definite MS and bladder issues (n=74) recruited from a tertiary hospital database were randomised to a treatment group (n=40) for an individualised bladder rehabilitation programme or to a control waitlist group (n=34). The Urogenital Distress Inventory (UDI6), Neurological Disability Scale (NDS) and the American Urological Association Symptom Index (AUA) assessed bladder impairment and 'activity limitation'; a single Quality of life (QoL) item in the AUA and the Incontinence Impact Questionnaire (IIQ7) measured restriction in 'participation'. Primary outcome measures were assessed at baseline and at 12 months.
                Analysis of per protocol data from 58 patients (treatment n=24, control n=34) showed reduced disability in the treatment group, with significant differences (p<0.001) and large effect sizes (>0.5) in post-treatment UDI6, NDS, AUA total, AUA QoL and IIQ7 scores for the two groups. The treatment group compared with the control group showed improvement: 78% versus 27% for UDI6 and 59% versus 17% improved for IIQ7. More patients in the control group deteriorated over the study period on the UDI6 (30% vs 0%; p<0.001) and IIQ7 (39 vs 0%; p=0.001).
                A multifaceted, individualised bladder rehabilitation programme reduces disability and improves QoL in pwMS compared with no intervention after 12 months of follow-up. Information on specific interventions in different bladder types in MS and the impact on QoL need further evaluation. Australian Clinical trials Registry ACTRNO12605000676617.
The use of anticholinergic drugs by people with overactive bladder syndrome results in statistically significant improvements in symptoms. Recent trials suggest that this is associated with modest improvement in quality of life. Dry mouth is a common side effect of therapy but did not seem to have an effect on the numbers of withdrawals. It is not clear whether any benefits are sustained during long-term treatment or after treatment stops.
