抗血小板口服 Ticlopidine is an antiplatelet drug with a mechanism of action different from that of aspirin or other nonsteroidal antiinflammatory drugs. Ticlopidine decreases platelet aggregation, and prolongs bleeding time. It may be useful in the prevention of thromboembolic disorders, cardiovascular mortality, stroke, myocardial infarction, and vaso-occlusive sickle cell crisis.
