WebThe two most commonly used NSAIDs (ibuprofen & naproxen) are relatively non-selective for inhibiting COX-1 vs COX-2, and therefore can produce unwanted side effects by … WebDifferences in safety and efficacy of the NSAIDs may be explained by relative selectivity for the COX-1 or COX-2 enzyme. Inhibition of COX-2 is thought to lead to the anti-inflammatory and analgesic actions of NSAIDs, whereas inhibition of COX- 1 is responsible for prevention of cardiovascular events and most adverse events.

Webslightly selective for COX-1 (eg, ibuprofen, naproxen, diclofenac) and others may be considered slightly selective for COX-2 (eg, etodolac, nabumetone, and meloxicam). The mechanism of action of celecoxib and rofecoxib is primarily selective inhibition of COX-2; at therapeutic concentrations, the COX-1 isoenzyme is not inhibited thus GI ... WebNSAIDs such as ibuprofen work by inhibiting the cyclooxygenase (COX) enzymes, which convert arachidonic acid to prostaglandin H 2 (PGH 2). PGH 2 , in turn, is converted by other enzymes to several other prostaglandins (which are mediators of pain, inflammation , and fever) and to thromboxane A 2 (which stimulates platelet aggregation, leading to the … Web56,57The advent of new selective COX-2Is has allowed the investigation of differential inhibition of COX-1 versus COX-2 58such that NSAIDs, new and old, can be evaluated 59–61with respect to their COX-1/COX-2 inhibitory profile . how do i create an itunes store account
