A comparative clinical study of hypolipidemic efficacy of Amla (Emblica officinalis) with 3-hydroxy-3-methylglutaryl-coenzyme-A reductase inhibitor simvastatin

Abstract

Objectives:To evaluate the efficacy of Amla in patients with type II hyperlipidemia and compare its hypolipidemic effects with those of simvastatin.Materials and Methods:Sixty type II hyperlipidemic patients of both sexes with plasma total cholesterol and low density lipoprotein level more than 240 mg% and 130 mg%, respectively, were selected for the trial. Out of total 60 selected patients, 40 were treated with Amla capsule (500 mg) daily for 42 days and 20 patients were given simvastatin capsule (20 mg) daily for 42 days. After the day of enrolment, all patients were followed up twice during the 42-day period. Blood samples were analyzed for various biochemical parameters and the values of Total Cholesterol (TC), Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), and Very Low Density Lipoprotein (VLDL) were measured before and after completion of the treatment with Amla and simvastatin. Cardiovascular parameters were recorded before and after completion of treatment.Results:Treatment with Amla produced significant reduction of TC (P<0.0001), LDL (P<0.0001), triglyceride (TG) and VLDL (P<0.0002), and a significant increase in HDL levels (P<0.0002). Similarly, treatment with simvastatin produced significant reduction of TC (P<0.0001), LDL (P<0.0009), TG and VLDL (P<0.017), and a significant increase in HDL levels (P<0.0001). Both treatments produced significant reduction in blood pressure; however, this beneficial effect was more marked in patients receiving Amla.Conclusion:In view of the above findings, it is suggested that Amla produced significant hypolipidemic effect along with a reduction in blood pressure. Addition of Amla to the currently available hypolipidemic therapy would offer significant protection against atherosclerosis and coronary artery disease, with reduction in the dose and adverse effects of the hypolipidemic agents.
