Antiplatelet agents work by inhibiting platelet aggregation, which is crucial in the formation of blood clots. Aspirin (ASA) inhibits the enzyme cyclooxygenase, which is necessary for thromboxane production, a promoter of platelet aggregation. Adenosine diphosphate (ADP) receptor blockers, such as clopidogrel, prevent ADP from binding to its receptor on the platelet surface, which is necessary for platelet aggregation. Glycoprotein IIb/IIIa receptor blockers, like abciximab, block the final common pathway for platelet aggregation by preventing fibrinogen from binding to its receptor on platelets. Thrombolytics are used to dissolve blood clots and are not antiplatelet agents. Antipyretic agents reduce fever and are not directly involved in inhibiting platelet aggregation.
