What distinguishes ticagrelor from prasugrel regarding the disadvantages of administration prior to elective CABG?

Ticagrelor is distinguished from prasugrel primarily by its pharmacokinetic profile, specifically its shorter half-life and quicker recovery of platelet function upon discontinuation. This shorter discontinuation time is particularly relevant for patients undergoing elective coronary artery bypass graft (CABG) surgery, as the risk of bleeding complications must be minimized while ensuring adequate antiplatelet effects are managed prior to the procedure.

When ticagrelor is stopped before surgery, its effects diminish faster compared to prasugrel due to the more rapid clearance and restoration of platelet function. This allows for better surgical timing, making ticagrelor a preferable choice in situations where urgent surgery may be necessary after antiplatelet therapy. In contrast, prasugrel, with its longer half-life, maintains its effects for a longer duration post-administration, potentially increasing the risk of perioperative bleeding if not properly timed before CABG.

This distinction is crucial for clinicians when considering preoperative management of patients requiring antiplatelet therapy. The flexibility offered by ticagrelor regarding the timing of surgery can lead to better outcomes in the management of patients needing CABG after cardiology intervention.
