Ditazole (4,5-diphenyl-2-bis-(2-hydroxyethyl)-aminoxazol) has been shown to be a strong in vitro inhibitor of human platelet aggregation brought about by release reaction inducers; in contrast, it did not significantly affect primary ADP-induced aggregation. Ditazole strongly inhibited the release of platelet-bound 14C-serotonin under the influence of Thrombofax, whereas it did not interfere with the transport and storage of serotonin in nonstimulated platelets. The effect of ditazole was not potentiated by acetyl-salicylic acid. Ditazole also inhibited ADP-reptilase clot retraction and modified thrombin-induced clot formation. The inhibition of platelet aggregation exerted by ditazole in plasma could be removed following gel filtration of platelets on Sepharose 2-B gel. This would indicate that ditazole does not act on platelets by a ‘hit and run’ mechanism.
