[0001]     This application claims the benefit of Provisional Application No. 60/821,674 filed Aug. 7, 2006. 
     
    
     FIELD OF THE INVENTION  
       [0002]     The present invention relates to a topical anti-itch composition for applying to the skin of a patient to treat psoriasis, eczema and other skin disorders and to a new carrier formulation for the topical delivery of medicaments and other active ingredients to be used in prescription drugs, over the counter drugs, and cosmetics containing active ingredients (cosmeceuticals).  
       BACKGROUND OF THE INVENTION  
       [0003]     Topical skin products are ubiquitous to the personal care, over the counter drug (OTC) and prescription drug markets. The delivery of drugs or other active ingredients is accomplished by placing the desired drug or active compound in a base that is typically a lotion, cream, gel, ointment, or other solution or suspension. Presently, there is a new trend in the personal care and topical drug industries (both OTC and prescription) wherein the term “cosmeceuticals” has become accepted as the blend between active ingredients and more standard products. There are many over the counter (OTC) and prescription products that are sold in the form of a lotion or gel or similar for the transdermal application of drugs or other active ingredients. Much research has focused on safely enhancing the absorption of said products as well as simultaneously providing therapeutic skin conditioners.  
         [0004]     Skin disorders, as the term is used herein, encompasses numerous skin conditions ranging in severity from severe dermatitis, severe dry skin, psoriasis, bacterial infections, fungal infections, acne, rosacea, scleroderma, skin stones etc., to less severe conditions, such as lack of adequate skin firmness, dermal hydration or sebum secretion, etc., which are nonetheless unsightly and may cause physical discomfort.  
         [0005]     The skin disorder Psoriasis is a non-contagious, lifelong skin disease that has been diagnosed in 4.5 million adults in the United States. The most common form, plaque psoriasis, appears as raised, red patches or lesions covered with a silvery white buildup of dead skin cells, called scale. Psoriasis is a very diverse skin disease that appears in a variety of forms. Each form has distinct characteristics. Typically, people have only one type of psoriasis at a time, but occasionally two or more different types of psoriasis can occur at the same time. Psoriasis can also occasionally change from one form to another. Trigger factors may “convert” some forms of psoriasis, such as plaque, to another form, such as pustular. Generally, one type of psoriasis will clear and then another form of psoriasis will appear later.  
         [0006]     Plaque psoriasis is the most prevalent form of the disease. About 80 percent of all those who have psoriasis have this form. Its scientific name is psoriasis vulgaris (vulgaris means common). It is characterized by raised, inflamed, red lesions covered by a silvery white scale. It is typically found on the elbows, knees, scalp and lower back.  
         [0007]     Guttate psoriasis is a form of psoriasis that often starts in childhood or young adulthood. The word guttate is from the Latin word meaning “drop.” This form of psoriasis resembles small, red, individual spots on the skin. Guttate lesions usually appear on the trunk and limbs. These spots are not usually as thick as plaque lesions. Guttate psoriasis often comes on quite suddenly. A variety of conditions have been known to bring on an attack of guttate psoriasis, including upper respiratory infections, streptococcal infections, tonsillitis, stress, injury to the skin and the administration of certain drugs (including antimalarials and beta-blockers). A streptococcal infection of the throat (strep throat) is a common guttate psoriasis trigger. Strep throat can be present without symptoms and can still cause a flare of guttate psoriasis. Talk with your doctor about getting a strep test to determine if you have an underlying strep infection. Guttate psoriasis may persist despite clearance of the strep infection. Some doctors prescribe antibiotics to help prevent an occurrence of an infection that can cause the outbreak of guttate psoriasis. Moisturizers are considered the preferred treatment for guttate psoriasis. However, people often find it tedious to apply topical preparations to the multiple small “drops” on their skin. Phototherapy treatment with ultraviolet light B (UVB) or PUVA (the light-sensitizing drug psoralen plus ultraviolet light A) is also very effective for guttate psoriasis. Only in severe cases will doctors prescribe systemic medications (drugs given orally or by injection) for this type of psoriasis, although sometimes a short course of one of these drugs results in rapid and prolonged clearing.  
         [0008]     Inverse psoriasis is found in the armpits, groin, under the breasts, and in other skin folds around the genitals and the buttocks. This type of psoriasis first shows up as lesions that are very red and usually lack the scale associated with plaque psoriasis. It may appear smooth and shiny. Inverse psoriasis is particularly subject to irritation from rubbing and sweating because of its location in skin folds and tender areas. It is more common and troublesome in overweight people and people with deep skin folds. Treatment can be difficult due to the sensitivity of skin in these areas. Steroid creams and ointments are considered very effective, but they should not be occluded (covered) with plastic dressings. Overuse or misuse of steroids, particularly in skin folds, can result in side effects, especially thinning of the skin and stretch marks. Because these areas are prone to yeast and fungal infections, doctors may test for infection and then may use diluted topical steroids in combination with other medications, for example, 1% or 2% hydrocortisone with anti-yeast or antifungal agents. Other topical agents, such as Dovonex, coal tar or anthralin, can be somewhat effective in treating psoriasis in skin folds, but they may also be irritating. They should be used with caution and under the direction of a doctor. People with severe inverse psoriasis may occasionally require systemic medications to control the condition. Protopic (also known by its generic name tacrolimus) and Elidel (also known by its generic name pimecrolimus) are two topical medications approved by the U.S. Food and Drug Administration for the treatment of eczema. Many dermatologists have found they work well for psoriasis lesions in the skin folds.  
         [0009]     Pustular psoriasis, primarily seen in adults, is characterized by white pustules (blisters of noninfectious pus) surrounded by red skin. The pus consists of white blood cells. It is not an infection, nor is it contagious. It may be localized to certain areas of the body—for example, the hands and feet. Pustular psoriasis also can be generalized, covering most of the body. It tends to go in a cycle-reddening of the skin followed by formation of pustules and scaling. Pustular psoriasis reportedly may be triggered by internal medications, irritating topical agents, overexposure to UV light, pregnancy, systemic steroids, infections, emotional stress and sudden withdrawal of systemic medications or potent topical steroids. It is not unusual for doctors to combine or rotate treatments for pustular psoriasis due to the potential side effects of systemic medications and phototherapy. More than one study has shown that Soriatane (also known by its generic name acitretin) and methotrexate in combination produced a rapid remission in the acute state of pustular psoriasis and an eventual clearing of the skin.  
         [0010]     Erythrodermic psoriasis is a particularly inflammatory form of psoriasis that often affects most of the body surface. It may occur in association with von Zumbusch pustular psoriasis. It is characterized by periodic, widespread, fiery redness of the skin. The erythema (reddening) and exfoliation (shedding) of the skin are often accompanied by severe itching and pain. Patients having an erythrodermic psoriasis flare should make an appointment to see a doctor immediately. Erythrodermic psoriasis causes protein and fluid loss that can lead to severe illness. Edema (swelling from fluid retention), especially around the ankles, may also develop along with infection. The body&#39;s temperature regulation is often disrupted, producing shivering episodes. Infection, pneumonia and congestive heart failure brought on by erythrodermic psoriasis can be life threatening. People with severe cases of this condition often require hospitalization. Known triggers of erythodermic psoriasis include abrupt withdrawal of systemic treatment; the use of systemic steroids (cortisone); an allergic, drug-induced rash that brings on the Koebner response (a tendency for psoriasis to appear on the site of skin injuries); and severe sunburns.  
         [0011]     Initial treatment usually includes medium-potency topical steroids and moisturizers, combined with wet dressings, oatmeal baths and bed rest. Antibiotics may also be used. Careful attention is paid to restoring and maintaining fluids in the body. In addition, methotrexate, Soriatane or cyclosporine are frequently required to bring severe cases under control. Use of systemic steroids for erythrodermic psoriasis is controversial, and if used, they should be tapered off slowly. Stopping them suddenly can trigger a flare of psoriasis. UVB or PUVA treatment is usually held in reserve until the degree of redness has improved.  
         [0012]     Eczema, or dermatitis as it is sometimes called, is a group of skin conditions which can affect all age groups. Up to one fifth of all children of school age have eczema, along with about one in twelve of the adult population. The severity of the disease can vary. In mild forms the skin is dry, hot and itchy, whilst in more severe forms the skin can become broken, raw and bleeding. Although it can sometimes look unpleasant, eczema is not contagious. With treatment the inflammation of eczema can be reduced, though the skin will always be sensitive to flare-ups and need extra care. The causes of eczema are many and varied, and depend on the particular type of eczema that a person has. Atopic eczema is thought to be a hereditary condition, being genetically linked. It is proposed that people with atopic eczema are sensitive to allergens in the environment which are harmless to others. In atopy there is an excessive reaction by the immune system producing inflamed, irritated and sore skin. Associated atopic conditions include asthma and hay fever. Other types of eczema are caused by irritants such as chemicals and detergents, allergens such as nickel, and yeast growths. In later years eczema can be caused by blood circulatory problems in the legs. The causes of certain types of eczema remain to be explained, though links with environmental factors and stress are being explored. There are several different types of eczema, many of which look similar but have very different causes and treatments. The first step in effective treatment of eczema is a correct diagnosis. It is very important to see a general practitioner in the first instance, who may make a referral to a specialist dermatologist for further diagnosis and treatment.  
         [0013]     Atopic eczema is the commonest form of eczema and is closely linked with asthma and hay fever. It can affect both children and adults, usually running in families. One of the most common symptoms of atopic eczema is its itchiness (or pruritis), which can be almost unbearable. Other symptoms include overall dryness of the skin, redness and inflammation. Constant scratching can also cause the skin to split, leaving it prone to infection. In infected eczema the skin may crack and weep (‘wet’ eczema). Treatments include emollients to maintain skin hydration and steroids to reduce inflammation.  
         [0014]     Allergic contact dermatitis develops when the body&#39;s immune system reacts against a substance in contact with the skin. The allergic reaction often develops over a period of time through repeated contact with the substance. For example, an allergic reaction may occur to nickel, which is often found in earrings, belt buckles and jeans buttons. Reactions can also occur after contact with other substances such as perfumes and rubber. In order to prevent repeated reactions it is best to prevent contact with anything that you know causes a rash.  
         [0015]     Irritant contact dermatitis this is a type of eczema caused by frequent contact with everyday substances, such as detergents and chemicals, which are irritating to the skin. It most commonly occurs on the hands of adults and can be prevented by avoiding the irritants and keeping the skin moisturized.  
         [0016]     Infantile seborrhoeic eczema is a common condition affecting babies under one year old, the exact cause of which is unknown. Also referred to as cradle cap, it usually starts on the scalp or the nappy area and quickly spreads. Although this type of eczema looks unpleasant, it is not sore or itchy and does not cause the baby to feel uncomfortable or unwell. Normally this type of eczema will clear in just a few months, though the use of moisturizing creams and bath oils can help to speed this along.  
         [0017]     Adult seborrheic eczema characteristically affects adults between the ages of 20 and 40. It is usually seen on the scalp as mild dandruff, but can spread to the face, ears and chest. The skin becomes red, inflamed and starts to flake. The condition is believed to be caused by a yeast growth. If the condition becomes infected, treatment with an anti-fungal cream may be necessary.  
         [0018]     Varicose eczema affects the lower legs of those in their middle to late years, being caused by poor circulation. Commonly the skin around the ankles is affected, becoming speckled, itchy and inflamed. Treatment is with emollients and steroid creams. If left untreated, the skin can break down, resulting in an ulcer.  
         [0019]     Discoid eczema is usually found in adults and appears suddenly as a few coin shaped areas of red skin, normally on the trunk or lower legs. They become itchy and can weep fluid. Usually discoid eczema is treated with emollients (and steroid creams if necessary).  
         [0020]     There are a number of ways to manage eczema, all of which begin with an effective skin care routine. Having access to accurate information is important as this allows the person with eczema, or their care giver, to make informed choices when managing the condition. The following are the more commonly used treatments. Further information on any of these can be obtained through the National Eczema Society.  
         [0021]     Emollients are necessary to reduce water loss from the skin, preventing the dryness normally associated with eczema. By providing a seal or barrier, the skin is less dry, itchy and more comfortable. Emollients are safe to use as often as is necessary and are available in various forms: ointments for very dry skin, creams and lotions for mild to moderate or ‘wet’ eczema. Some are applied directly to the skin, whilst others are used as soap substitutes or can be added to the bath. The range of emollients available is enormous and it may be necessary to try several before the most suitable one is found. Testing a small amount on the skin first is advisable, as emollients contain substances to which some people are sensitive.  
         [0022]     Topical steroids. When eczema is under control, only emollients need to be used. However in flare-ups, when the skin becomes inflamed, a steroid cream may be needed. Steroids act by reducing inflammation and are used in most types of eczema. Topical steroids come in four different strengths, mild, moderately potent, potent and very potent. The strength of steroid cream that a doctor prescribes depends on the age of the patient, the severity of the condition and, the size of the area and part of the body to be treated. Topical steroids are applied thinly to the affected area, as directed by the prescribing doctor. Your eczema should be reviewed regularly if topical steroids are being applied. It is important to use only the steroid cream prescribed for yourself and not to lend or borrow (what may be) an unsuitable cream from someone else. Many people have concerns regarding the use of topical steroids and their side-effects. As long as steroids are used appropriately and as directed by your doctor, the likelihood of side effects is very rare. Reported side-effects have been largely due to the use of very potent steroid preparations over long periods of time.  
         [0023]     Acne vulgaris is the most common of all skin disorders. It is a chronic inflammatory process that affects the pilosebaceous unit in virtually every adolescent and in many adults and prepubertal children as well. As such, it carries with it a heavy emotional and psychological burden.[1] Marion Sulzberger, MD, one of the founding figures of modern dermatology, wrote in 1948 that “there is no single disease which causes more psychic trauma, nor maladjustment between parents and children, more general insecurity and feelings of inferiority and general sums of psychic suffering than does acne vulgaris.”[2] The impact can be devastating, leading even to thoughts of suicide. But the impact is not entirely psychological. Research by William Cunliffe, MD, in the United Kingdom, showed that patients with acne had a higher unemployment rate than age- and sex-matched controls.[3] 
         [0024]     Dr. Cunliffe also has studied the prevalence of facial acne in adults. A 1999 community-based study [4]  showed that 12% of women over the age of 25 had clinical acne, and acne prevalence did not significantly decrease until after age 44. These figures agree with the clinical experience of many physicians, who report seeing increasing numbers of adult acne patients—especially women—in their practices.  
         [0025]     Acne vulgaris evolves within the pilosebaceous unit (FIG. 1) via a multifactorial pathogenesis. The central pathogenic factors in acne are [5,6] : 
        Excessive sebum production secondary to androgen stimulation;     Abnormal follicular keratinization resulting in follicular plugging;     Proliferation of  Propionibacterium acnes  ( P acnes ), an anaerobic organism normally resident in the follicle; and     Inflammation following chemotaxis and the release of various proinflammatory mediators.        
 
         [0030]     The increase in adrenal androgens during the prepubertal period triggers the enlargement of the sebaceous glands. These enlarged sebaceous glands produce increased amounts of sebum, which flows through the canal of the sebaceous follicle. This canal is lined with a keratinizing epithelium. In acne patients, there is increased production of the follicular corneocytes lining the follicle and retention of these corneocytes within the follicle. The abnormally desquamated corneocytes and the excess sebum build up within the follicle to form a microscopic, bulging mass. This enclosed, sebum-rich environment is ideal for the proliferation of  P acnes , the anaerobic bacterium that produces chemotactic factors and recruits proinflammatory molecules involved in the inflammatory phase of acne.  
         [0031]     Inflammatory acne lesions include papules, pustules, nodules, and cysts. A papule is a pink-to-red, raised, palpable lesion with no visible accumulation of fluid, which can range from 1 to 4 mm in diameter.  
         [0032]     A pustule is a raised accumulation of purulent material on the skin&#39;s surface, and is similar in size to the papule. Pustules are sometimes characterized as superficial or deep. In a superficial pustule there is a localized rupture of the epithelium near the skin surface, and in a deep pustule there is extensive destruction of the entire epithelium. A nodule is a tender, firm lesion that may persist for weeks. Cysts may be as large as several centimeters in diameter, and they may drain a creamy, yellowish material. Darkly pigmented skin affected by acne tends to develop significant postinflammatory hyperpigmentation. This tendency has given rise to the suggestion that a new acne lesion should be designated [7] —the acne hyperpigmented macule (AHM). The AHM can last for 4 months or longer, and is often the central complaint of acne patients with skin of color.  
         [0033]     Topical therapy for acne can be divided into topical antimicrobials/antibiotics, topical retinoids, and miscellaneous topical therapy. Benzoyl peroxide (BP) is an antimicrobial that is very effective for killing  P acnes . Products containing BP are widely available by prescription and over the counter. BP, however, has minimal impact on microcomedo formation and is generally best used in combination with topical retinoids (see below). BP-containing products are available in a variety of formulations, including gels, creams, lotions, washes, and bar soaps, in a variety of concentrations (most often 2.5%, 5%, and 10%). Concentration should be adjusted to skin type and tolerance, since BP may cause skin irritation, erythema, and dryness. Patients also should be advised that BP will bleach colored fabrics.  
         [0034]     Topical antibiotics kill  P acnes  and also exhibit significant anti-inflammatory properties. Thus, while topical antibiotics do not have a major effect on comedo formation, they are active against inflammatory lesions such as papules and pustules. Because, like BP, these drugs do not have a major impact on comedo formation, they are most often used in combination with topical retinoids (see below). The most widely prescribed topical antibiotics are erythromycin and clindamycin. Topical clindamycin 1% and topical erythromycin 1.5% have been shown in a double-blind, randomized trial to be clinically equivalent in the treatment of moderate facial acne, [15]  and it is estimated that topical clindamycin is approximately equivalent to a 500-mg dose of tetracycline. [16]  Topical erythromycin and clindamycin were originally available as hydroalcoholic solutions dispensed in applicator bottles. Hydrophilic gels and lotions were developed in an attempt to reduce irritation and enhance patient convenience and compliance. More recently, the pledget delivery system has become widely used. Erythromycin is also available in a creamy ointment formulation (Akne-Mycin).  
         [0035]     Newer products combine topical BP and either erythromycin (3% erythromycin, 5% BP; Benzamycin) or clindamycin (1% clindamycin, 5% BP; BenzaClin, Duac) in gel vehicles. Clinical studies enrolling patients with mild to moderately severe acne have demonstrated the increased efficacy of the combination products compared with either agent alone, without increased side effects. [17,18]  The emergence of antibiotic-resistant  P acnes  is an issue of increasing concern with both topical and oral antibiotics in the treatment of acne. [19,21]  Over the past 25 years, laboratory studies have demonstrated a rapidly increasing pattern of  P acnes  resistance to antibiotics, especially erythromycin. This seems to be less likely with clindamycin. For this reason, it seems prudent to minimize the use of topical and/or oral antibiotics in acne, replacing them as soon as possible with BP and/or topical retinoids. Combination therapy with topical antibiotics and BP or the use of a combination product containing BP and erythromycin or clindamycin may also prevent the emergence of drug-resistant  P acnes.   [22,23]   
         [0036]     The topical retinoids include vitamin A acid (tretinoin), its analogs, and newer agents that bind to and activate retinoid receptors. Topical retinoids are the treatment of choice for comedonal acne and are definitely the most effective agents for clearing microcomedones. Initially, topical retinoids were prescribed only for comedonal acne. Today, however, there is strong evidence that topical retinoids have both direct and indirect anti-inflammatory actions, [24]  and their use in inflammatory acne is expanding rapidly. The emerging consensus among acne experts is that topical retinoids are a front-line therapy for inflammatory acne and should be used early in treatment. [25]  Topical retinoids seem to be especially effective in combination therapy with BP or topical antibiotics. Such combination therapy seems quite logical when one recalls the basic pathophysiology of acne, ie, a combination of comedo formation, proliferation of  P acnes , and inflammation. Thus, the value of a regimen that combines antibiotics to kill  P acnes  and suppress inflammation with topical retinoids to resolve comedones and add additional anti-inflammatory effects is clear. Another, newer concept in the use of topical retinoids is maintenance therapy. [25]  Studies have shown that after acne has resolved clinically, microcomedones (the primary lesions in acne) begin to recur. Thus, it would seem reasonable to use topical retinoids in virtually all acne patients who have cleared in order to prevent or reduce recurrence.  
         [0037]     The major problem in using topical retinoids has been irritation. Irritation, strongly associated with the earlier retinoids, has led to 2 significant clinical misconceptions. The first misconception is that irritation might be necessary for retinoids to achieve therapeutic success. The emergence of less irritating but very effective topical retinoids (see below) has disproved this notion. Cutaneous irritation is clearly an undesirable side effect of retinoid use and may be attenuated by using a product with low irritancy potential and carefully instructing patients in proper skin care (wash gently with tepid water and mild soaps or soap substitutes; avoid washcloths and astringents; use sunscreens; and avoid excessive sun exposure). The second misconception is that retinoids should not be used in inflammatory acne. Several studies now show that retinoids possess direct and indirect anti-inflammatory properties [24]  and should be first-line therapy for inflammatory acne. Another concern is the risk of teratogenicity with topical retinoids. Tazarotene, for example (see below), is a pregnancy category X drug. Since only minute amounts of topically applied retinoids ever reach the bloodstream, such a risk seems remote. Nevertheless, it would be prudent to avoid the use of topical retinoids in pregnant women. Irritation was a particular problem with the first-generation pioneering topical retinoid tretinoin. Newer formulations of tretinoin aim to reduce irritation through the use of vehicles that slow release of the active agent. One such product (Avita), available in 0.025% gel or cream vehicles, uses polymer compounds to slow release of the tretinoin and reduce irritation. [26]  Another (Retin-A Micro) slows drug delivery and decreases irritation by incorporating the active ingredient into microsponges.  
         [0038]     A newer generation of receptor-selective retinoids, such as adapalene (Differin) and tazarotene (Tazorac), may have certain therapeutic advantages over tretinoin. Adapalene is a third-generation retinoid that selectively targets retinoic acid receptors found primarily in the epidermis. The drug modulates cellular differentiation, keratinization, and inflammatory processes. [27]  Adapalene is available in 0.1% gel, solution, cream, and pledget formulations.  
         [0039]     In an investigator-masked, randomized, parallel-group, multicenter trial enrolling patients with mild-to-moderate acne, adapalene gel 0.1% was significantly more effective at reducing inflammatory and noninflammatory lesions than was tretinoin gel 0.025%. [28]  Adapalene gel 0.1% has been found to be as effective as tretinoin cream 0.05%. [29]  The most common adverse effects associated with adapalene treatment are erythema, scaling, dryness, pruritus, and burning. In comparative trials, [28,29]  adapalene gel was better tolerated than tretinoin 0.025% gel and 0.05% cream. In tests of cumulative irritation potential in healthy subjects, [30]  adapalene gel 0.1% was better tolerated than tretinoin 0.1%, 0.05%, and 0.025% creams; tretinoin 0.025% and 0.01% gels; and tretinoin 0.1% gel microsphere. Tazarotene, a synthetic acetylenic retinoid, is another third-generation receptor-selective retinoid. The drug modulates cellular differentiation, proliferation, and the inflammatory process. It is available in 0.1% cream and gel formulations for the treatment of acne.  
         [0040]     In a double-blind, multicenter, randomized, parallel-group trial [31]  enrolling patients with mild-to-moderate acne, tazarotene 0.1% gel was more effective than 0.025% tretinoin gel in reducing noninflammatory lesions and as effective in reducing inflammatory lesions. Tazarotene gel was also found to be more effective than tretinoin 0.1% microsponge gel as measured by overall disease severity and noninflammatory lesion count. [32]  A double-blind, randomized, parallel-group trial found tazarotene 0.1% gel to be more effective than adapalene 0.1% gel in the treatment of mild-to-moderate acne. [33]   
         [0041]     Older therapies still available include various products containing sulfur, resorcinol, and salicylic acid. These are generally less effective than the newer topical agents discussed above. A relatively new agent is azelaic acid (Azelex), a dicarboxylic acid available in a 20% cream with efficacy against inflammatory (and to a lesser degree, comedonal) lesions. Azelaic acid may also be useful in treating cutaneous hyperpigmentation, including acne-induced postinflammatory hyperpigmentation. In clinical trials, treatment of mild-to-moderate acne with azelaic acid has shown efficacy comparable to that of tretinoin 0.05%, benzoyl peroxide 5%, and topical erythromycin 2%. [35]  The most frequent adverse reactions are pruritus, burning, stinging, and tingling.  
         [0042]     It has therefore been shown the hydrocortisone is a common, safe, and accepted treatment for psoriasis, eczema, acne, and other skin disorders in the form of a topical cream or lotion. Hydrocortisone is a steroid hormone secreted by the adrenal cortex. Commercially, it is available as the unchanged hormone and as hydrocortisone acetate, hydrocortisone cypionate, hydrocortisone sodium phosphate, hydrocortisone butyrate, hydrocortisone valerate, and hydrocortisone sodium succinate. Hydrocortisone is the preferred glucocorticoid for replacement therapy in patients with adrenal insufficiency, although some patients require concomitant administration of a more potent mineralocorticoid, such as fludrocortisone, to treat this condition. Topical hydrocortisone is considered low potency. Low potency topical corticosteroids are the safest for chronic use and may be used on the face or intertriginous areas, with occlusion, and in infants and young children. Hydrocortisone was approved by the FDA in 1951.  
         [0043]     Endogenous corticosteroids are secreted by the adrenal cortex, and their effects are believed to be due to enzyme modification rather than to a direct hormone-induced action. Corticosteroids are loosely classified into two categories, mineralocorticoids and glucocorticoids, depending on their primary pharmacological activity. Mineralocorticoids alter electrolyte and fluid balance by facilitating sodium resorption and hydrogen and potassium excretion at the level of the distal renal tubule, resulting in edema and hypertension. Glucocorticoids exert some mineralocorticoid effects but are also involved in a number of other metabolic pathways including gluconeogenesis, fat redistribution, protein metabolism, and calcium balance. Hydrocortisone possesses both mineralocorticoid actions and glucocorticoid actions.  
         [0044]     Corticosteroids exhibit anti-inflammatory, antipruritic, and vasoconstrictive properties. At the cellular level, corticosteroids induce peptides called lipocortins. Lipocortins antagonize phospholipase A 2 , an enzyme which causes the breakdown of leukocyte lysosomal membranes to release arachidonic acid. This action decreases the subsequent formation and release of endogenous inflammatory mediators including prostaglandins, kinins, histamine, liposomal enzymes and the complement system. Topical preparations of hydrocortisone are metabolized in the skin, while systemic hydrocortisone is metabolized by the liver to inactive metabolites. These inactive metabolites, as well as a small portion of unchanged drug, are excreted in the urine. The biological half-life of hydrocortisone is 8-12 hours.  
         [0045]     Coal tar is indicated for the symptomatic management of pruritus and irritation caused by dandruff, seborrheic dermatitis, atopic dermatitis, eczema, and psoriasis. Treatment with coal tar and UV light or sunlight can be beneficial because of its photosensitizing action. Official USP coal tar preparations include crude coal tar, coal tar topical solution, and coal tar ointment. Crude coal tar is produced as a byproduct secondary to the destructive distillation of coal, and it can be further refined into coal tar topical solution or ointment. Commercially available preparations that are not officially recognized by USP and do not have specifications for composition include coal tar extract and distillate. Application of crude coal tar preparations may be aesthetically displeasing to the patient; however, further refined products are believed by many clinicians to be therapeutically inferior. It has been suggested that the variability in refining processes may be responsible for differences in therapeutic response to coal tar preparations. Coal tar was in use prior to 1938 and approved by the FDA at its inception.  
         [0046]     Coal tar exhibits keratoplastic and mild irritant activity. Coal tar may decrease the quantity and size of epidermal cells produced and inhibit mitosis, possibly through removal of oxygen in the skin. Shampoo and soap preparations may exert their action through absorption into the epidermis and enhancement of scale removal. It has been suggested that a reaction similar to that following exposure to sunlight can occur in the epidermis through interaction between the peroxides in coal tar and epidermal sulfhydryl groups. Subsequently, epidermal proliferation may be decreased. Coal tar preparations are also believed to possess antipruritic, antiseptic, astringent, antifungal, vasoconstrictive, and photosensitizing properties. Coal tar is reportedly carcinogenic in humans, inducing skin cancer primarily in the anogenital region, following prolonged exposure to coal tar in industrial settings. It is unlikely that patients treated acutely for dermatologic conditions are at an increased risk for developing skin cancer. Nevertheless, this risk should be considered during prolonged treatment periods.  
         [0047]     Most coal tar preparations used for dermatologic disorders contain 2-5% coal tar. Coal tar is applied topically in various formulations such as creams, gels, ointments, bath preparations, shampoos, liquid preparations (lotions and emulsions), and cleansing bars and solutions. The location and type of lesion will determine the appropriate formulation. It is unknown if coal tar preparations pose a fetal risk or if they are distributed into breast milk (see Contraindications). Coal tar and salicylic acid are used together in a topical preparation to treat eczema, psoriasis, and seborrheic dermatitis. Coal tar has keratoplastic action as well as antipruritic and anti-eczematous actions. Salicylic acid is added for its keratolytic activity.  
         [0048]     Many such products exist presently in both prescription and over the counter drug forms. The most common over the counter form of hydrocortisone is 0.25 to 1.00% by weight creams comprised of a viscous fatty acid carrier and the drug. Some of these products incorporate various emollients, moisturizers, pH modifiers, emulsifiers, preservatives, or other excipients. Many times, the base used to supply the active ingredient is chosen partly in order to adequately solubilize or emulsify the desired drug or actives such that said actives are stable in the product formulation and do not interact with the other product components during manufacture, storage, or application. Ingredients for the preparation of stable lotions, gels, etc. include polymers that provide the substantive body or viscosity of the preparation, emollients that provide good skin feel, moisturizers that help to keep water on the surface of the skin, emulsifiers that keep all the ingredients in one homogeneous state, preservatives that keep the product from going rancid with microbial growth, chelating agents and antioxidants that scavenge free radicals and heavy metals that can reduce viscosity and cause an undesirably appearance and/or smell, and fragrance or colorants that enhance the appearance and smell of the product.  
         [0049]     Traditional topical creams and lotions that contain one or more active or drug are comprised of waxy fatty acids that are melted and neutralized that provide a creamy base for the addition and emulsification of other ingredients. Stearic and palmitic acid are two common cream bases that used in products such as anti-itch creams or psoriasis treatments like coal tar and salicylic acid preparations. Recently, manufacturers have begun to add skin conditioning ingredients such as aloe or vitamin E to these products as well.  
         [0050]     Many of the products that treat symptoms or indications of skin disorders come in a cream carrier that is difficult to spread, especially over damaged, sensitive skin. Additionally, many of the existing products reply on the drug or active to manage the symptoms or indications of the skin disorder. These products build the lotion base to accommodate the medicament, typically using stearic acid, palmitic acid, or petrolatum as the vehicle.  
         [0051]     Several formulations have been proposed to overcome the disadvantages of the prior art, both for treating skin disorders, and for use in cosmetics in order to prevent skin irritation and clear blemishes.

         [0067]     Medicine or other active ingredients may be added to the formulation in oil or water phase from approximately 10-30% by weight.  
         [0068]     The composition of the present invention is able to receive and hold with great stability many different medicaments or active cosmetic compounds. Depending upon the end use of the formulation, various medicines and/or cosmetic ingredients may be added into the oil or water water phase of the product prior to making the emulsion. These compounds, hereafter referred to as active ingredients or “actives” range in form and function and are outlined in the following paragraphs.  
         [0069]     Analgesics: Most commercial topical analgesics use a counter-irritant, such as methyl salicylate, menthol, camphor, eucalyptol and derivatives or mixtures thereof, or rubefacients, such as capsicum, oleoresin chloroform and the like, formulated as an ointment or gel.  
         [0070]     The use of counter-irritants and rubefacients to achieve analgesia are well known in the art. Arora, U.S. Pat. No. 5,223,257, discloses an analgesic composition of methyl salicylate, olive oil, eucalyptus oil and isopropyl alcohol. Nichols, U.S. Pat. No. 5,223,267, discloses an analgesic composition of cellulosic powder, counter-irritant (salicylates, menthol, comphor, eucalyptol), analgesic (aspirin, triethanolamine salicylate, ibuprofen), steroid (hydrocortisone), mineral oil, emollient and alcohol. Fisher, U.S. Pat. No. 3,880,996, discloses a preparation of salicylate, menthol, polysiloxane and a vasodilator, such as histamine. Beck, U.S. Pat. No. 5,073,366, discloses a composition containing camphor and eucalyptus oil. Elden, U.S. Pat. No. 5,814,659, discloses a topical composition of a lidocaine analgesic, benzyl alcohol, urea, fatty acid, emulsifier, gel, preservative and organic base. Saitoh et al, U.S. Pat.

No. 4,120,976, discloses the use of methylenedioxyamphetamine to treat arthritis. None of the above cited patents teach or suggest the use of the method and composition outlined in the present invention.  
         [0071]     Nonsteroidal Anti-Inflammatory Agents  
         [0072]     Nonsteroidal anti-inflammatory agents (NSAIDs) are also useful in relieving pain and tissue swelling, chiefly by inhibiting the biosynthesis of prostaglandins. In small doses, NSAIDs have an analgesic action, but full doses have both analgesic and anti-inflammatory actions, and are effective in reducing pain and swelling. While pain relief from a headache can be obtained with a single 200-400 mg dose of ibuprofen, a full anti-inflammatory effect for bursitis might require 3,200 mg/d of the same drug. NSAIDs fall in seven major classes: proprionic acid derivatives, indole derivatives, fenamates, pyrrolealkanoic acids, pyrazolone derivatives, oxicams and salicylic acids.  
         [0073]     Adult Daily Suggested Daily NSAID Oral Dosage Topical Dosage Indomethacin 200 mg 50 mg Sulindac 400 mg 100 mg Tolmetin 1,800 mg 500 mg Piroxicam 20 mg 5 mg Diclofenac potassium 200 mg 50 mg Diclofenac sodium 200 mg 50 mg Fenoprofen 3,200 mg 800 mg Flurbiprofen 300 mg 70 mg Ibuprofen 3,200 mg 800 mg Ketoprofen 300 mg 70 mg Naproxen 1,500 mg 350 mg Etodolac 1,200 mg 300 mg Aspirin 3,600 mg 800 mg Diflunisal 1,500 mg 350 mg  
         [0074]     Anti-inflammatory Agents: Inflammation is a fundamental pathologic process involving complex reactions that occur in the affected blood vessels and adjacent tissues in response to an injury or abnormal stimulation caused by a physical, chemical, or biologic agent. The acute inflammatory response begins after cellular injury due to microorganisms, physical agents (such as burns, radiation, and trauma), chemicals, necrotic tissue, and immunological reactions. Five classic signs are manifested in acute inflammation; redness, heat, pain and loss of function. These signs are induced by changes which take place in the microvasculature (arterioles, capillaries, and venules) and the interstitial areas (fluid-filled regions between cells and tissues). These include changes in vascular flow and caliber, changes in vascular permeability, and leucocyte exudation. The first change involves vasodilation of the vessels and increased blood flow. The second change involves increased permeability of the blood vessels with a movement of fluid and proteins out of the vessels creating edema of the tissues. The final change occurs as white blood cells infiltrate and accumulate in the surrounding tissue. The increased blood flow and permeability of the microvascular system at the inflamed body part facilitates treatment to the area by using a penetration enhancer to deliver the bio-affective agents.  
         [0075]     The spread of the acute inflammatory response following injury to a small area of tissue suggests that chemical substances are released from injured tissues, spreading outwards into uninjured areas. These chemicals, called endogenous chemical mediators, cause vasodilation, emigration of neutrophils, chemotaxis and increased vascular permeability. Histamine is a chemical mediator in acute inflammation and causes vascular dilatation and vascular permeability. It is stored in mast cells, basophil and eosinophil leucocytes, and platelets. Histamine release is stimulated by complement components C3a and C5a and by lysosomal proteins released from neutrophils. Prostaglandins are a group of long-chain fatty acids derived from arachidonic acid. They increase vascular permeability, and platelet aggregation. Drugs such as aspirin and NSAIDs inhibit one of the enzymes involved in prostaglandin synthesis. Other chemical mediators include; leukotrienes, serotonin and lymphokines. Plasma contains four enzymatic cascade systems; complement, the kinins, the coagulation factors and the fibrinolytic system.  
         [0076]     Chronic inflammations are characterized by a longstanding dull pain, and indurated swelling, and the presence of granulation tissue. The predominant cells seen in chronic inflammation are the mononuclear leukocytes, such as macrophages, lymphocytes, and plasma cells. A fibroblastic proliferation is seen more often than a fluid exudate. Some bio-affective agents with anti-inflammatory properties are the following:  
         [0077]     CORTICOSTERIODS: Alclometasone dipropionate, Amcinonide, Augmented betamethasone dipropionate, Beclomethasone dipropionate, Betamethasone, Betamethasone benzoate, Betamethasone dipropionate, Betamethasone sodium phosphate, Betamethasone valerate, Clobetasol propionate, Clocortolone pivalate, Cortisone, Desonide, Desoximetasone, Dexamethasone, Dexamethasone acetate, Dexamethasone sodium phosphate, Diflorasone acetonide, Diflorasone diacetate, Flunisolide, Fluocinolone acetonidem, Fluocinonide, Fluocinolone acetonide, Flurandrenolide, Fluticasone propionate, Halcinonide, Halobetasol propionate, Hydrocortisone, Hydrocortisone acetate, Hydrocortisone butyrate, Hydrocortisone sodium phosphate, Hydrocortisone valerate, Methylprednisolone, Methylprednisolone acetate, Methylprednisolone sodium succinate, Mometasone furoate, Prednisolone acetate, Prednisolone sodium phosphate, Prednisolone tebutate, Prednisone, Triamcinolone, Triamcinolone acetonide, Triamcinolone diacetate, Triamcinolone hexacetonide  
         [0078]     Methyl-Sulfonyl-Methane: Methyl-sulfonyl-methane (MSM) or dimethyl sulfone is essentially DMSO with an extra oxygen molecule and lacks the lipid-solubility of DMSO, but can be coupled with another penetration enhancer. In the body, MSM gives up its sulfur to form methionine and cysteine for connective tissue. MSM is anti-inflammatory and analgesic and useful for muscle soreness and cramps, prevents cartilage degeneration and improves joint flexibility. The therapeutic dosage range for MSM is 2-10 grams orally per day. The recommended topical dosage range is 1-5 grams.  
         [0079]     Numerous patents for MSM were filed by Herschler. U.S. Pat. No. 4,296,130, discloses a method for softening skin; U.S. Pat. No. 4,477,469 discloses a composition of MSM and carbamide to soften skin; U.S. Pat. No. 4,863,748 discloses a method for adding sulfur to the diet with MSM; U.S. Pat. No. 4,973,605 discloses a method for treating muscle cramps associated with arthritis with oral MSM; and U.S. Pat. No. 5,071,878 discloses a method for using MSM in a diet for sulfur and health reasons. None of the above cited patents teach or suggest the use of the method and composition outlined in the present invention.  
         [0080]     Zinc Compounds: Osteoporosis is characterized by progressive loss of bone architecture and mineralization leading too the loss of bone strength and an increased fracture rate. The skeleton is constantly being remodeled by a balance between osteoblasts, that lay down new bone, and osteoclasts, that break down or resorb bone.  
         [0081]     Zinc plays a physiological role in the regulation of bone metabolism, by stimulating bone formation and mineralization and an inhibitory effect on bone resorption. Zinc activates aminoacyl-tRNA synthetase in osteoblastic cells, stimulates cellular protein synthesis, and inhibits osteoclast-like cell formation in marrow cells. Bone zinc content is decreased by development, with aging, skeletal unloading, and postmenopausal conditions. Zinc plays a role in the preservation of bone mass. Most zinc compounds, such as zinc sulfate, are useful for the prevention of osteoporosis, but a recent study confirmed that .beta.-Alanyl-L-histidinato zinc (AHZ) has a potent effect on bone formation and calcification. Yamaguchi M, Role of Zinc in Bone Formation and Bone Resorption, J. of Trace F. Elements and Experimental Medicine 1998; 11:119-135.  
         [0082]     Zinc compounds have anti-inflammatory and anti-infective properties. In a recent published article, Petrus E J et al., Current Therapeutic Research, 1998; 59/9: 595-607, the inventor served as chief investigator for a randomized, double-masked, placebo-controlled clinical study of the effectiveness of zinc acetate lozenges on common cold symptoms in allergy-tested subjects. Those subjects who used the zinc lozenges had both a shorter duration and severity of common cold symptoms. Those subjects who were positive for allergies, were more responsive to zinc by having a shorter duration of nasal symptoms. The study cited many references that reported the following benefits and effects of zinc compounds:  
         [0083]     Zinc is an essential trace element in human biology that is known to be necessary for many biologic functions, such as growth, appetite, testicular maturation, skin integrity, mental activity, wound healing, and immune system maintenance. Approximately 300 enzymes are known to require zinc for their activities. Zinc deficiency in humans is widespread and is more prevalent in areas where the population subsists on cereal proteins. Clinical manifestations of zinc deficiency include: growth retardation, hypogonadism in males, neurosensory disorders, cell-mediated immunological dysfunctions, increased maternal morbidity, premature delivery, and adversely affects the proliferation, regulation and maturity of lymphocytes.  
         [0084]     Zinc has been shown to be an essential element for the function of the immune system. Regarding the effect of zinc on allergies, it is known that mast cells have been implicated as mediators of Type I allergic reactions. Mast cell derived reactions result from the release of histamine, heparin, prostaglandins, SRS-A, and various vasoactive amines from granules on the surface of mast cells, possibly including kinins. One product of mast cell-induced inflammation is fever. The inhibitory effect of zinc on histamine release from mast cells are attributed to its action on the stabilization of the mast cell membrane. Zinc ions were found to stabilize cell plasma membranes and prevent induced histamine and vasoactive amine release from tissue mast cells. It has been observed that unsequestered zinc ions (4 to 20 millimolar) are released in inflammation from mast cell granules suggesting a common linkage with inflammation. Zinc is a competitive antagonist of the calcium-dependent IgE and f-met peptide mediated histamine release from human basophils and suggested that zinc compounds might be considered for the treatment of autoimmune disorders.  
         [0085]     Zinc compounds are acknowledged as anti-inflammatory agents, as astringents and beneficial in wound healing, and have antimicrobial, antifungal and antiviral activity. Zinc is the active agent in formulations to treat diaper rash, decubitus ulcers, and abrasions. Zinc stabilizes the cell membranes and inhibits the formation of free radicals. Zinc also strengthens the integrity of blood vessel walls by reducing the membrane permeability and stopping bleeding. Unlike other metals, zinc is virtually nontoxic.  
         [0086]     Aloe Vera Extract: Aloe vera has been well reported to have anti-inflammatory and analgesic properties, but its use in treating musculoskeletal disorders has only recently been described. One study treated patients with a diagnosis of fibromyalgia and/or chronic fatigue syndrome with aloe vera gel extract and found that there was a remarkable reduction in initial symptom severity and continued improvement during the course of the study. Dykman K D, Tone C, Ford C, Dykman R A, The effects of nutritional supplements on the symptoms of fibromyalgia and chronic fatigue syndrome. Interg Physiol Behav Sci 1998 January-March; 33:61-71. Both topical and oral treatments with aloe vera were found to increase the synthesis of glycosaminoglycans and enhance would healing.

Aloe vera also increased the biosynthesis of collagen. Chithra P, Sajithlal G B, Chandrakasan G, Influence of Aloe vera on collagen turnover in healing of dermal wounds in rats.

         [0087]     The use of Aloe vera is well known in the art. Carpenter et al, U.S. Pat. No. 5,786,342, discloses a method of reducing symptoms associated with chronic respiratory diseases using acetylated mannan from aloe vera. Strickland et al, U.S. Pat. No. 5,824,659, discloses the use of a oligosaccharide from Aloe to inhibit the loss of skin immunocompetency from ultraviolet irradiation.
