title: Influence of a hypolipemic drug (procetofene) on platelet functions and lipid composition in type II B hyperlipoproteinemia.
abstract: Platelet function was evaluated in platelet-rich plasma and in washed platelets in relation to their lipid composition, in 18 type II B hyperlipoproteinemic men treated with procetofene. The results were compared to those obtained in 15 young, healthy normolipemic controls and in 22 untreated male subjects with type II B hyperlipoproteinemia. In addition to completely normalizing platelet functions, procetofene was able to induce a 28-53% decrease in serum cholesterol and triglycerides. Solely, the aggregation to ADP (secondary), arachidonic acid and epinephrine was higher in the untreated hyperlipoproteinemic subjects. This increased susceptibility to aggregation does not appear to be related to the cholesterol or cholesterol-phospholipid content of platelets.
