Efficacy and safety of slow-release fluvastatin 80 mg daily in Chinese patients with hypercholesterolemia.
BACKGROUND
Before this study, the efficacy and safety of doubling the dosage of fluvastatin from 40 mg/day to 80 mg/day in Chinese patients with primary hypercholesterolemia remained to be determined.


METHODS
In this open-label, active-controlled randomized 2-center study, patients with primary hypercholesterolemia were randomized to treatment with immediate-release fluvastatin 40 mg/day (n = 30) or slow-release fluvastatin 80 mg/day (n = 31) for 12 weeks. The primary efficacy variable was percent change in low-density lipoprotein (LDL) cholesterol level from baseline. Secondary efficacy variables were percent changes in total cholesterol, triglyceride, and high-density lipoprotein (HDL) cholesterol levels, and the percent of patients achieving LDL cholesterol goals of the US National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) II.


RESULTS
Both fluvastatin dosages (40 mg/day vs 80 mg/day) effectively reduced LDL cholesterol (-22.5% vs -29.9%; p = 0.087), total cholesterol (-17.3% vs -22.5%; p = 0.140), and triglyceride levels (-14.0% vs -12.3%; p = 0.813) (all p < 0.0001 for comparison with baseline), and slightly increased HDL cholesterol levels (+5.2% vs +5.6%; p = 0.917), after 12 weeks of treatment. The percent of patients achieving LDL cholesterol goals of the NCEP ATP II was 37% versus 65% (p < 0.05). The adverse event profiles for the 2 fluvastatin dosages were similar.


CONCLUSIONS
In Chinese patients with primary hypercholesterolemia, doubling the dosage of fluvastatin from 40 to 80 mg once daily was effective and safe regarding reduction of LDL cholesterol level, and allowed more patients to achieve LDL cholesterol goals of the NCEP ATP II.
