Bezafibrate retard in type II diabetic patients: Effects on hemostasis and glucose homeostasis

A double-blind, placebo-controlled trial assessed the effect of a slow-release formulation of bezafibrate (Bezalip Mono, 400 mg daily for 3 months) on lipid profile, glucose homeostasis, platelet function, and plasma fibrinogen concentration in non-insulin-dependent (type II) diabetics. Twenty-four patients completed the trial. There was a significant improvement in the cholesterol (p < 0.02), triglyceride (p < 0.01), and nonesterified fatty acid (p < 0.05) concentrations and in the fasting blood glucose (p < 0.03) and glycosylated hemoglobin (p < 0.01) levels of those (n = 11) who received the active preparation but not in those (n = 13) who received placebo. Treatment, but not placebo, also resulted in a significant (p < 0.01) fall in plasma fibrinogen concentration and a trend towards inhibition of platelet aggregation. Bezafibrate was well tolerated; only one patient (not included in the analysis of results) withdrew from the trial possibly because of side effects of the drug. A larger study is needed to establish whether bezafibrate can reduce nonlipid risk factors (e.g., plasma fibrinogen concentration, glucose intolerance, and hyperinsulinemia) in normo- and hyperlipidemic subjects.
