Abstract

Background: The fixed-dose combination containing the antihypertensive agent amlodipine and thestatin, atorvastatin, is the first combination of its kind designed to treat two risk factors forcardiovascular disease (CVD), i.e., hypertension and dyslipidemia. In this study, blood pressure andlipid lowering effects of combination of amlodipine and atorvastatin were evaluated in uncontrolledhypertensive patients. Methods: Thirty patients both male and female in the age group 35–60 yearsattending the Hypertensive Clinic of PMRC FJMC suffering from uncontrolled hypertension wereselected. Baseline blood pressure was checked after half hour rest in sitting and standing position usingmercury sphygmomanometer. Blood sample was collected from all patients after overnight fasting forassessment of serum cholesterol, triglycerides, LDL and HDL cholesterol levels. They were prescribedwith fixed dose combination of 5 mg amlodipine and 10 mg atorvastatin. Patients were followed fortheir blood pressure measurement after every 4 weeks up to 12 weeks. At the end of 12 weeks theirfasting blood sample was taken again for determination of serum cholesterol, triglyceride, LDL andHDL cholesterol levels. Results: Systolic blood pressure after 4, 8 and 12 weeks was significantlylower at all intervals from baseline. When systolic blood pressure after 8 and 12 weeks was comparedwith 4 weeks, the effect was again significant (p=0.024, p=0.002 respectively).There was no significantreduction seen in 8 versus 12 weeks (p=0.493). Diastolic blood pressure at 4, 8 and 12 weeks wassignificantly lower from baseline. Diastolic blood pressure after 4 and 8 weeks when compared with 8and 12 weeks was not significantly low (p=0.99 and 0.91 respectively). Lipid profile of the patients wassignificantly reduced from baseline after twelve weeks of fixed dose combination of treatment(p<0.000). Conclusion: Combination therapy proved to be effective in controlling hypertension anddyslipidemia than single pill. It also improved patient’s compliance. It is suggested that polypill shouldbe prescribed instead of multiple drugs.Keywords: combination therapy, atorvastatin, amlodipine, uncontrolled hypertension, dyslipidemia
