 Description
Features and Benefits 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 plaets that blocks thromboxane production and plaet aggregation. Chemopreventive against colorectal and other solid tumors.
