Potentiating effects of clofibrate on prostaglandin-dependent and -independent pathways of human platelet activation: evidence for involvement of cyclic AMP.

Abstract:

:Although clofibrate has been shown to inhibit platelet aggregation that is caused by thrombin, ADP and epinephrine, by blocking the release of arachidonic acid from platelet phospholipids [8], here we have demonstrated that clofibrate enhanced platelet aggregation by arachidonic acid and PLC and reversed the effects of PGE1 on platelet cAMP concentration and on PLC-induced secretion of [14C]-5HT in similar, concentration-dependent manners. Taken together, these findings strongly suggest that the proaggregatory effect of clofibrate is mediated by a lowering of cAMP in platelets.
