Increased levels of total cholesterol and low density lipoprotein cholesterol (LDL-C) are associated with the development of coronary artery disease, which has become a worldwide public health problem. Clinical trials show that, in the long term, effective lowering of total cholesterol and raising of high density lipoprotein cholesterol (HDL-C) can slow atherosclerosis progression and reduce coronary artery disease risk. This study evaluated the efficacy, safety, and tolerability of fluvastatin versus bezafibrate (slow release) in patients with cholesterol > 241 mg/dL (6.2 mmol/liter) not responding to dietary treatment alone (cholesterol < 300 mg/day for 8 weeks). Patients were divided into 2 groups: group A (13 women, 7 men; mean age, 47.8 +/- 9.7 years; range, 30-70) received 40 mg fluvastatin once daily with their evening meal; group B (14 women, 6 men; mean age, 45 +/- 11 years, range, 25-68) received 400 mg bezafibrate once daily with either breakfast or their evening meal. After 12 weeks of treatment, the mean cholesterol decrease in group A was 27% (from 271 +/- 51.4 to 197.4 +/- 24.3 mg/dL; p < 0.001) versus 8% (from 278.6 +/- 33.2 to 255.8 +/- 20.3 mg/dL; p < 0.005) in group B. At the same time point, LDL-C was significantly decreased in group A (from 197.9 +/- 49 to 107.5 +/- 27.6 mg/dL; p < 0.001) but not in group B (from 181.6 +/- 39.6 to 173.3 +/- 24.3 mg/dL).(ABSTRACT TRUNCATED AT 250 WORDS)
