Name two P2Y12 inhibitors used in ACS and a key consideration for one of them.

Block P2Y12 receptors on platelets to prevent aggregation is a cornerstone of antiplatelet therapy in ACS. Two P2Y12 inhibitors commonly used are clopidogrel and ticagrelor. Clopidogrel is a prodrug that requires metabolic activation and tends to have a slower, more variable onset with generally lower bleeding risk. Ticagrelor is a direct-acting, reversible inhibitor with a faster onset and stronger platelet inhibition, and to achieve rapid protection it is given with a loading dose up front. A key consideration for ticagrelor is its higher bleeding risk (and potential dyspnea), which influences selection and timing, especially around procedures. This combination—clopidogrel and ticagrelor—fits the clinical scenario, and highlighting ticagrelor’s loading dose and bleeding risk captures an important practical point for managing ACS.
