[Bezafibrate in primary hyperlipidemias (author's transl)].

The effect of long-term treatment over 40 weeks with Bezafibrate on lipids and lipoproteins was investigated in 27 patients with primary hyperlipoproteinemias (hlp) (12 patients with hlp type IV, 7 patients with type IIb, 3 patients with type IIa, 4 patients with type V and 1 patient with type III). Bezafibrate reduced total cholesterol by 16%, whereas HDL-cholesterol increased by 28% and 36% (p less than 0.05). Serumtriglycerides decreased by 59% (450 mg Bezafibrate daily) and by 66% (600 mg Bezafibrate daily) statistically significant (p less than 0.05). In hyperlipidemias type IV, IIb, IIa and V increases of HDL-cholesterol could be observed. The course of LDL-cholesterol was different in the various types of hlp. The postheparin-lipoprotein-lipase (PHLA) was activated by treatment with Bezafibrate from 10.5 +/- 0.7 to 14.7 +/- 0.7 and 15.5 +/- 0.8 mumol FFA/ml/h or by 30% (p less than 0.05). Only few side-effects during treatment with Bezafibrate could be ascertained.
