Irreversible cyclooxygenase-1 and 2 inhibitor
WebJan 14, 2004 · As COX-1 inhibition by aspirin is irreversible, there is a cumulative inhibition of TXA 2 generation by platelets when low doses of aspirin are administered chronically [ 5 ]. There is a non-linear relationship between inhibition of platelet TXA 2 generation and inhibition of TXA 2 -dependent platelet aggregation. WebCOX-1 vs COX-2 Inhibitors Cyclooxygenase (COX) is the enzyme responsible for converting arachidonic acid to prostaglandins and their product. Prostaglandins are the group of chemical mediators which are made at the site of tissue damage or in the infected site causing inflammation and pain. Cyclooxygenase has two different enzymes (McCuiston …
