title: The influence of ketanserin on hemostasis in vitro.
abstract: Ketanserin is a new selective 5-HT2 receptor blocker. It has been used to indirectly study the influence of serotonin on hemostatic function in vitro. Coagulation and fibrinolysis in vitro were not affected. In high doses adrenalin induced platelet aggregation was inhibited but no influence was seen on collagen or ADP induced aggregation. It can be concluded that it is not very likely that serotonin plays an important role in initial hemostasis. However, the findings ought to be confirmed in vivo.
