[Interactions of platelet inhibitors].

Combination effects of inhibitors of platelet function with different mechanisms of action such as adenosine, acetylsalicylic acid, papaverine, dipyridamole, and sodium nitroprusside were studied in vitro by means of ADP- and collagen-induced aggregation of human blood platelets. In case of ADP-induced aggregation, potentiation of the inhibitory effect was observed only with the combination adenosine-papaverine, whereas in case of collagen-induced aggregation the inhibitory effect was potentiated at various inhibitor combinations.
