[Long-term bezafibrate treatment in a lipid clinic].

The files of 122 patients treated for at least 6 months with bezafibrate, a second generation fibric acid derivative, were reviewed. Our indications for bezafibrate treatment included cases of type IIb, IV and V hyperlipidemia which did not respond to a serious dietetic trial. Mean decrease in plasma triglycerides was 45% and in cholesterol 1012%, while in HDL-cholesterol there was a mean increase of 8%. The drug was usually well tolerated. Thorough review of patient files for side effects revealed gastrointestinal disturbances in 6.5%. There was a decrease in libido in 4%. 2 patients developed gynecomastia, 1 abnormal liver function tests and 1 severe myositis. All side effects were fully reversed on discontinuing the drug. Bezafibrate seems to be well-tolerated and suitable for treating type IIb, IV and V hyperlipidemia unresponsive to diet.
