The authors report the results of an open clinical study using 400 mg Bezafibrate once a day. Among 25 diabetic patients (type II.) underwent a 4 weeks period with nutritional advice. Average changes from inclusion levels were -24% for total cholesterol, -56% for triglicerides, +11.9% for HDL-cholesterol, -19% for plama fibrinogen. In conclusion, bezafibrate at a daily dose of 400 mg had significant lipid-modifying properties but also exhibited a beneficial effect on other related risk factors such as fibrinogen reduction.
