Biochem/physiol Actions

Blocks the production of prostaglandins by inhibiting cyclooxygenase (prostaglandin H synthase), with greater selectivity toward the COX-1 isoform. The antithrombotic effect is due to the inhibition of COX-1 in platelets that blocks thromboxane production and platelet aggregation. Chemopreventive against colorectal and other solid tumors.

Bleeding limits anticoagulant treatment in patients with acute coronary syndromes (ACS). We investigated whether background concomitant antiplatelet therapy influences the effects of apixaban after ACS. This study examined high-risk ACS patients who were treated with aspirin or aspirin plus clopidogrel

We investigated whether use of low-dose enteric-coated (EC) aspirin for secondary prevention of cardiovascular events has sufficient bioavailability to achieve complete platelet cyclooxygenase (COX) inhibition in all individuals. Aspirin reduces cardiovascular morbidity and mortality in patients with pre-existing vascular disease;
