Abstract

Background and objectives: Hyperlipidemia is characterized by increased concentrations of lipids including triglycerides, total cholesterol, low density lipoproteins, very low density lipoproteins in the blood and some times decreased high density lipoproteins .Many drugs have been used for treatment of this disorder. The present study was designed to estimate the effects of simvastatin on lipid profile, atherogenic index, transaminases, creatinine, uric acid and alkaline phosphatase.Methods: This study covered 70 subjects, they were divided into two groups, the first group included 45 hyperlipidaemic patients which were treated with 20mg simvastatin and second group included 25 normal subjects. After 12 hours fasting, serum lipid profile, transaminases; alkaline phosphatase, uric acid and creatinine were measured for the patients in 3 intervals before treatment, after 8 weeks and 16 weeks of treatment, and one time for normal subjects.Results: : After therapy, simvastatin showed a significant reduction in serum (TC, TG, LDL, VLDL and atherogenic index) and also, significant rise in HDL noticed, by performing a comparison between the group before treatment, and groups after treatment.Serum ALT, AST and ALP were significantly increased but were still within normal levels.Insignificant effect was observed from serum creatinine, uric acid and also body mass index by performing a comparison between group before treatment and groups after treatment.Conclusions:Simvastatin was effective in controlling lipid profile and atherogenic index, with no significant abnormality in liver functions.

Abstract

Background and objectives: Lowering the blood cholesterol and low density lipoprotein levels may reduce the risk of coronary heart disease. This study was designed to evaluate the effect of lipid-lowering therapy by simvastatin 20 mg versus atorvastatin 20mg on patients suffering from hyperlipidemia.Method: This study is 16-weeks duration included 75 patients with hyperlipidemia. Patients were assigned randomly to receive either simvastatin 20 mg/day group (1), or atorvastatin 20 mg/day group (2). After 12 hours fasting, lipid profile, atherogenic index and alanine aminotransferase were assessed for the patients at baseline, 8-weeks and at the end of 16-weeks of treatment.Results: After therapy for both groups of patients, as compared to the levels at the baseline, the serum total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) were significantly reduced while high density lipoprotein cholesterol (HDL-C) was significantly increased. Serum alanine aminotransferase (ALT) increased by both groups of treatment with no significant differences between the two modes of treatment.Conclusion: After treatment with simvastatin 20 mg and atorvastatin 20 mg, there were a reduction in total cholesterol, triglyceride, LDL-C, and VLDL-C, and an increase in HDL-C in both groups. Comparing the two types of treatment, atorvastatin 20 mg was more effective in lowering triglyceride and VLDL-C than simvastatin 20 mg while Simvastatin led to greater reduction in LDL-C. Both modes of treatment were well tolerated by the patients.
