hypertension is ranked as the third most , important risk factor for attributable burden of disease in south asia . around the globe , about 1 billion patients are affected by hypertension and the burden is rising owing to escalating obesity and population aging and by 2025 it is projected that about 1.5 billion of patients will be affected worldwide . cardiovascular risk factors , including hypertension , tend to co - segregate more commonly than would be expected by chance . genetic studies have established a clear association between hypertension and dyslipidemia . the term dyslipidemic hypertension ( dh ) was first used in 1988 , in the context of familial dyslipidemia along with hypertension , which was proposed as a genetic syndrome found in approximately 12% of the patients with essential hypertension and 48% of the hypertensive sib ships . dyslipidemia , a strong predictor of cardiovascular disease ( cvd ) , causes endothelial damage [ 6 - 9 ] , and the loss of physiological vasomotor activity that results from endothelial damage may become manifested as increased blood pressure ( bp ) . therefore , factors like dyslipidemia that cause endothelial dysfunction may lead to hypertension . according to recent joint national committee 8 guidelines  , calcium channel blockers ( ccbs ) are one of the first - line recommended drugs for the treatment of hypertension . out of various subtypes of ca channels ( i.e. l , n , t , p / q , and r ) , clinically used common ccbs act on primarily l - type , t - type and n - type calcium channels . structurally , ccbs are divided into the dihydropyridine type and the non - dihydropyridine type [ 11 , 12 ] . by regulating the release of norepinephrine from sympathetic nerve ending , the n - type voltage - dependent calcium channel plays an important role in sympathetic neurotransmission . cilnidipine is a novel and unique 1,4-dihydropyridine derivatives calcium antagonist with potent inhibitory action against both l - type and n - type voltage - dependent calcium channels . it has been reported that once daily administration of cilnidipine resulted in a safe and more effective lowering of bp in essential hypertension without reflex tachycardia than similar administration of other dihydropyridine calcium antagonists . angiotensin ii , a major villain of the raas pathway , promotes atherogenesis through stimulation of the angiotensin type 1 receptor ( at1 ) , which increases lipid uptake in cells , vasoconstriction , and free radical production , to foster both hypertension and atherosclerosis . in animal models , n - type ccbs not only suppress the sympathetic overactivity but also have cardioprotective and renoprotective effects . these changes in lipid levels are important in hypertensives , as up to 40% of the newly diagnosed hypertensives have at least one lipid abnormality . considering the effect on plasma lipid alpha - blockers , the raas blocker or the ccb may be the preferred initial therapy in patients with underlying dyslipidemia . among the various groups of antihypertensive drugs available in the market , selecting the appropriate drug as per individual clinical profile of patient the aim of this study was to evaluate the effectiveness of cilnidipine in patients with essential hypertension with borderline dyslipidemia and its effects on lipid profile . the aim of this study was to evaluate the effectiveness of cilnidipine in patients with essential hypertension with borderline dyslipidemia and its effects on lipid profile . this was an interventional , randomized , open - label , parallel assignment , effectiveness study . we enrolled 45 patients with newly diagnosed essential hypertension along with borderline high lipid profile who presented to outpatient clinic of cardiology , rajendra institute of medical sciences ( rims ) , ranchi , during january 2016 . patients were included in the study if they met the following criteria :  40 years of age of both sex , systolic blood pressure ( sbp)/diastolic blood pressure ( dbp ) of  140/90 mm hg to  180/110 mm hg , borderline dyslipidemia not requiring drug treatment ( total cholesterol 200 - 239 mg / dl and/or triglyceride 150 - 199 mg / dl and/or ldl 130 - 159 mg / dl and/or hdl 40 - 60 mg / dl ) . patients with secondary hypertension of any causes , angina pectoris or acute coronary artery disease , recent history of congestive heart failure , valvular heart diseases , cardiac arrhythmias , renal dysfunction ( serum creatinine level > 2.0 mg / dl ) and diabetes mellitus were excluded . patients of any existing clinical condition which did not allow safe completion of the protocol and safe administration of study medication were also excluded . eligible study subjects were treated with cilnidipine started at 10 mg / day , and then adjusted to 5 - 20 mg / day if target bp was not achieved by 4 weeks . if cilnidipine failed to reduce the bp to the target level , an angiotensin - converting - enzyme ( ace ) inhibitor and/or angiotensin ii receptor blocker ( arb ) were added and these patients were excluded from the study . patients were followed on second , fourth , eighth and 12th week and at each visit in office , sbp and dbp and heart rate were recorded . bp was recorded three consecutive times and the average was taken as final value , using mercury sphygmomanometer . the 12-h fasting blood samples were taken at baseline and at 12th week between 9 am and 11 am lipid profile was measured by an automatic biochemical analysis system . this study was conducted in accordance with the principles outlined in the declaration of helsinki after receiving approval from the institutional ethical committee of rims , ranchi . the primary outcomes included changes in heart rate , sbp , dbp and lipid profile in hypertensive patients following 12 weeks treatment with cilnidipine . this was an interventional , randomized , open - label , parallel assignment , effectiveness study . we enrolled 45 patients with newly diagnosed essential hypertension along with borderline high lipid profile who presented to outpatient clinic of cardiology , rajendra institute of medical sciences ( rims ) , ranchi , during january 2016 . patients were included in the study if they met the following criteria :  40 years of age of both sex , systolic blood pressure ( sbp)/diastolic blood pressure ( dbp ) of  140/90 mm hg to  180/110 mm hg , borderline dyslipidemia not requiring drug treatment ( total cholesterol 200 - 239 mg / dl and/or triglyceride 150 - 199 mg / dl and/or ldl 130 - 159 mg / dl and/or hdl 40 - 60 mg / dl ) . patients with secondary hypertension of any causes , angina pectoris or acute coronary artery disease , recent history of congestive heart failure , valvular heart diseases , cardiac arrhythmias , renal dysfunction ( serum creatinine level > 2.0 mg / dl ) and diabetes mellitus were excluded . patients of any existing clinical condition which did not allow safe completion of the protocol and safe administration of study medication were also excluded . eligible study subjects were treated with cilnidipine started at 10 mg / day , and then adjusted to 5 - 20 mg / day if target bp was not achieved by 4 weeks . if cilnidipine failed to reduce the bp to the target level , an angiotensin - converting - enzyme ( ace ) inhibitor and/or angiotensin ii receptor blocker ( arb ) patients were followed on second , fourth , eighth and 12th week and at each visit in office , sbp and dbp and heart rate were recorded . bp was recorded three consecutive times and the average was taken as final value , using mercury sphygmomanometer . the 12-h fasting blood samples were taken at baseline and at 12th week between 9 am and 11 am lipid profile was measured by an automatic biochemical analysis system . this study was conducted in accordance with the principles outlined in the declaration of helsinki after receiving approval from the institutional ethical committee of rims , ranchi . the primary outcomes included changes in heart rate , sbp , dbp and lipid profile in hypertensive patients following 12 weeks treatment with cilnidipine . we analyzed the data of 22 men and 15 women with mean age of 54.17  3.35 years and mean body mass index ( bmi ) of 27.31  3.7 . out of initially enrolled 45 patients , eight were lost in follow - up or excluded from the study due to side effects or inadequate control of bp with study medication by eighth week or due to requirement of lipid - lowering drug during the first 4 weeks of the study . table 1 summarizes the baseline characteristics of the patients enrolled for this study . there were no significant differences in background factors before and after the study . table 2 shows sbp , dbp and mean bp decreased significantly after treatment with cilnidipine . heart rate reduced significantly from baseline . in the lipid profile , while total cholesterol , ldl and hdl showed no significant change , serum triglyceride level reduced significantly after 12 weeks of treatment by cilnidipine from the baseline values . we analyzed the data of 22 men and 15 women with mean age of 54.17  3.35 years and mean body mass index ( bmi ) of 27.31  3.7 . out of initially enrolled 45 patients , eight were lost in follow -

type calcium channels . similar reduction of heart rate in cilnidipine treated patients has also been reported in other studies . increase mortality from cvd in japanese population [ 11 , 12 ] and in american   patients with hypertension has been observed to be associated with a higher heart rate . reflex tachycardia is a common side effect associated with many dihydropyridine ccbs which act through l - type calcium channel only . replacing these drugs with cilnidipine , a dual l- and n - type ccb may reduce the heart rate and can potentially reduce the mortality in hypertensive patients . graphical representation of changes of sbp , dbp and mean bp from baseline after 12 weeks of cilnidipine treatment . graphical representation of changes in heart rate from baseline after 12 weeks of cilnidipine treatment .   in this study , we showed that after 12 weeks of treatment , there is a significant reduction in the level of triglyceride ( fig . similar reduction of triglyceride was found in hypertensive rats fed with high fat diet and studies done in patients of type 2 diabetes with hypertension treated with cilnidipine [ 20 - 23 ] . by blocking the n - type calcium channel , cilnidipine , indirectly causes blockade of the -receptors and improves the lipid profile by producing peripheral vasodilation , which may facilitate glucose and lipid uptake by muscle cells . furthermore , -receptor blockade may also increase the availability of lipoprotein lipase for triglyceride hydrolysis . blockade of hepatic -1-adrenoceptors may modulate glycogenolysis and gluconeogenesis , decrease triglyceride output from the liver , reduce cholesterol synthesis , and accelerate binding of ldls to their hepatic receptors . although the role of triglycerides as an independent risk factor for cvd has been under debate , there is increasing evidence from recent studies demonstrating moderately high triglycerides ( 150 - 500 mg / dl ) are associated with increased cardiovascular risk . in a recently published meta - analysis involving more than 200,000 patients from 29 studies ( including the reykjavik study and the epicnorfolk study ) , moderately strong associations were observed between triglyceride concentrations and chronic heart disease ( chd ) risk even with low baseline triglyceride concentrations . it has been suggested that the attenuation of the effect of triglycerides on the prediction of future chd events when hdl cholesterol and other risk factors are included in models is due to the biological variability of triglycerides compared with that of hdl . when this variability is taken into account , graphical representation of variation in lipid profile , before and after 12 weeks of treatment . cilnidipine by virtue of its triglyceride reducing property may provide better mortality protection in hypertensive patients . a small number of patients were enrolled in this study for a period of 12 weeks only . therefore , a large number of patients and long - term follow - up may be needed to confirm the consistency our results . taken together , the results from this study allow us to conclude that cilnidipine ( n- and l - type ccbs ) exerts hypotensive activity , and on the other hand , unlike other dihydropyridine , it reduces heart rate and also improves triglyceride level . considering these features , cilnidipine is a promising drug of choice for targeting patients with hypertension and hypertriglyceridemia , since both disorders often coexist in clinical setting . a small number of patients were enrolled in this study for a period of 12 weeks only . therefore , a large number of patients and long -

backgroundmany epidemiological studies have established the relationship between hypertension and dyslipidemia . 
 calcium channel blockers ( ccbs ) are one of the first - line drugs for newly diagnosed patients with essential hypertension . 
 cilnidipine as a newer ccb acting by blocking both l- and n - type calcium channels possesses additional beneficial effects apart from lowering blood pressure ( bp ) . 
 the aim of this study was to evaluate the effectiveness of cilnidipine in patients with essential hypertension with borderline dyslipidemia and its effects on lipid profile.methodsout of 45 enrolled patients , who fulfilled the inclusion criteria , only 37 completed the study . 
 cilnidipine was started at 10 mg / day , and then adjusted to 5 - 20 mg / day to achieve the target blood pressure.resultsafter 12 weeks of study , patients showed significant reduction in systolic blood pressure , diastolic blood pressure , mean bp , heart rate and serum triglyceride level from baseline values ( p < 0.00).conclusionin clinical setting where both hypertension and hypertriglyceridemia exist , cilnidipine can be a promising drug of choice .
