Comparative Study of the Effects and the Safety of Different Dose of Simvastatin on Aged Patients With Hyperlipidemia / 中国医师杂志

ABSTRACT

Objective To investigate the effects and the safety of different dose of simvastatin on aged patients with hyperlipidemia.Method The 70 patients were divided into two groups at random. 40 in group A was given orally simvastatin 20 mg/d, and 30 patients in group B was given orally simvastatin 40 mg/d,respectively; The levels serum total cholesterol(TCH), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C) and triglyceride(TG) were measured following the 4th week, the 8th week and the 12th week . And the changes of the functions of the patients'liver and kidney, the serum glucose level and the activities of myocardial enzymes in the two groups before and after the simbastatin treatment were also observed. Results In the 4th , 8th and 12th week at the treatment with simvastatin 20mg/d, the patients' TCH levels were decreased by 32 1%,32 1%,36 0% respectively;the TG levels were decreased by 35 1%,49 6%,52 9% respectively;the LDL levels were decreased by 39 3%,37 3%,35 2% respectively;and the HDL-C levels were increased by 2 0%,0 8%,8 3%, respectively. While in the 4th, 8th and 12th week at the treatment of simvastatin 40mg/d,the patients' TCH levels were decreased by 41 8%,48 0%,51 0%, TG levels were decreased by 18 4%,32 3%,38 4%, the LDL levels were decreased by 42 4%,47 5%,50 8%, and the HDL-C levels were increased by 1 0%,2 0%,13 0% respectively. There were no obviously changes of the results of the tests of the liver function,the kidney function,the blood glucose level and the myocardial enzymes before and after both treatment groups in the different dose of the simvastain. Conclusion The effects and the safety of the treatments of simvastatin on aged patients with hyperlipidemia were similar at the dose of 20mg/d and the dose of 40mg/d.
