    Abstract:
    A total of 123 patients with primary hypercholesterolemia were randomized on a 2:1 ratio to receive either fluvastatin at 20 mg once daily at night (n = 82) or gemfibrozil at 600 mg twice daily (n = 41) in a double-blind, double-dummy comparison of the effects on plasma lipid parameters and tolerability over 8 weeks. All patients had either low-density lipoprotein cholesterol (LDL-C) concentrations > or = 160 mg/dL (4.1 mmol/L) in association with definite coronary artery disease (CAD) or > or = 2 risk factors, or LDL-C > or = 190 mg/dL (4.9 mmol/L) with no CAD and < 2 risk factors. All had triglyceride (TG) levels < or = 350 mg/dL (4.0 mmol/L). After 8 weeks of treatment, fluvastatin produced significant reductions from baseline of 17.4% (p < 0.001) in LDL-C, 13.2% (p < 0.001) in total cholesterol (TC), 13.8% (p < 0.001) in very low-density lipoprotein cholesterol (VLDL-C), and 6.4% (NS) in TG. High-density lipoprotein cholesterol (HDL-C) was increased by 5.6% (p < 0.001), and the ratio of LDL-C:HDL-C (Friedewald) was decreased by 21.2% (p < 0.001). Gemfibrozil reduced LDL-C by 15.8%, TC by 13.4%, VLDL-C by 32.2%, LDL-C:HDL-C by 24.8%, and TG by 34.2%, and increased HDL-C by 13.9% (all changes were statistically significant, p < 0.001) compared with baseline. Gemfibrozil produced significantly greater changes in VLDL-C (p < 0.01), HDL-C (p < 0.001), and TG (p < 0.001), but not in LDL-C: HDL-C, compared with fluvastatin. Both drugs significantly reduced apolipoprotein (apo) B and lipoparticles (Lp) E:B, and increased apo A-I but had divergent effects on LpA-I (increased with fluvastatin and reduced with gemfibrozil; p < 0.05). At the end of the study, 43.8% of fluvastatin patients and 45% of gemfibrozil patients achieved a reduction of > 20% in LDL-C levels. Normalization of LDL-C levels was achieved (according to European Atherosclerosis Society guidelines) by 13.4% of fluvastatin- and 14.6% of gemfibrozil-treated patients. Both drugs were well tolerated; adverse events occurred in 36.6% of fluvastatin recipients compared with 58.5% of patients taking gemfibrozil. No clinically notable elevations of aspartate or alanine aminotransferases, alkaline phosphatase, or creatine phosphokinase occurred. No patient developed new or worsening lens opacities associated with a reduction in optically corrected visual acuity. The most commonly reported adverse events were headache and gastrointestinal upset. There were no serious drug-related adverse events.
