Which one of the following is FALSE about Ticlopidine?: (A) Inhibits platelet function by inducing a thrombasthenia like state, (B) Stimulates platelet aggregation and clot retraction, (C) Prolongs the bleeding time, (D) Directly interacts with platelet membrane glycoprotein IIb/IIIa receptors
Answer is B. (B) Stimulates platelet aggregation and clot retraction# Aspirin, Ticlopidine, Dipyridamole are antiplatelet drugs.> Ticlopidine interacts with platelet membrane GP llb/llla & alters fibrinogen binding to platelets.> Ticlopidine inhibits platelet aggregation & clot retraction. It has no effect on TXA2, but bleeding time is prolonged.
