Naproxen's medical uses are related to its mechanism of action as an anti-inflammatory compound. [11] Naproxen is used to treat a variety of inflammatory conditions and symptoms that are due to excessive inflammation, such as pain and fever (naproxen has fever-reducing, or antipyretic, properties in addition to its anti-inflammatory activity). [11]
COX-2 is an enzyme facultatively expressed in inflammation, and it is inhibition of COX-2 that produces the desirable effects of NSAIDs. [125] When nonselective COX-1/COX-2 inhibitors (such as aspirin, ibuprofen, and naproxen) lower stomach prostaglandin levels, ulcers of the stomach or duodenum and internal bleeding can result. [126]
On its own, COX enzyme synthesizes prostaglandins, creating inflammation. In whole, the NSAIDs prevent the prostaglandins from ever being synthesized, reducing or eliminating the inflammation and resulting pain. [citation needed] Some common examples of NSAIDs are aspirin, ibuprofen, and naproxen. The newer specific COX-inhibitors are not ...
With an estimated 52.5 million adults in the U.S. affected by arthritis alone and up to 24% of adults experiencing muscle pain during their lifetime, effective topical pain relievers can be life ...

A phase II study showed no significant differences in efficacy between naproxcinod and the COX-2 inhibitor rofecoxib in the treatment of pain. [ 10 ] In osteoarthritis, a 750 mg dose is equipotent to 500 mg of naproxen for the treatment of inflammation but with the added benefit of attenuating the cardiovascular effects traditionally associated ...
Prostaglandin inhibitors are drugs that inhibit the synthesis of prostaglandin in human body. [1] There are various types of prostaglandins responsible for different physiological reactions such as maintaining the blood flow in stomach and kidney, regulating the contraction of involuntary muscles and blood vessels, and act as a mediator of inflammation and pain.
The VIGOR trial results were published in 2000 in the New England Journal of Medicine [47] Bombardier and his research team claimed that there was "an increase in myocardial infarction in the patients given rofecoxib (0.4%) compared with those given naproxen (0.1%)" and "patients given naproxen experienced 121 side effects compared with 56 in ...
