<prompt> With respect to ticlopidine, clopidogrei:Is more likely to cause formation of antiplatelet antibodies15 less likely to cause neutropeniaIs more likely to cause severe bleedingHas a greater antiplatelet effect  <response>: Ref: KDT 6e p610 Ticlopidine and clopidogrel are ADP antagonists and are used as antiplatelet drugs. Antiplatelet action, chances of bleeding and formation of antibodies is similar with these two agents. Clopidogrel is better tolerated because it is less likely to cause severe neutropenia and thrombocy topenia as compared to ticlopidine.
