Effect of Ticlopidine, 5-(2-chlorobenzyl)-4, 5, 6, 7-tetrahydro3,2-Cpyridine hydro-chloride, on platelet aggregation was studied in the rat. Ticlopidine was found to be a potent, long-lasting inhibitor of platelet aggregation. It inhibited the aggregation induced by any of ADP, collagen, thrombin, arachidonic acid and prostaglandin endoperoxides and/or thromboxane A2-like substancee. Ticlopidine was effective at doses as low as 30 mg/kg when orally given to rats, and the effect lasted as long as the life span of the circulating platelets (half time: about 48 hours). Ticlopidine inhibited also nucleotide release from and prostaglandin synthesis in the platelets, but did not significantly affect platelet adhesiveness to glass, platelet factor 3 availability and clot retraction.
