May support 48-hour aspirin dosing to balance inhibition and recovery in surgical patients; leaves open confirmation in outcome trials.
Does aspirin 40 mg every 48 hours compared to every 72 hours optimize the balance of platelet thromboxane A2 and vascular prostacyclin synthesis in patients undergoing elective surgery for varicose veins?
Aspirin 40 mg every 48 hours may provide the optimal balance of inhibiting platelet thromboxane A2 synthesis while allowing vascular prostacyclin synthesis recovery, potentially maximizing antithrombotic effects.
