https://www.ncbi.nlm.nih.gov/mesh/68009288
Naproxen (naproxen sodium, NAPROSYN®) is a propionic acid derivative related to the arylacetic acid group of nonsteroidal anti-inflammatory drugs (NSAIDs). It is an anti-inflammatory agent with analgesic and antipyretic properties. Both the acid and its sodium salt are used in the treatment of rheumatoid arthritis and other rheumatic or musculoskeletal disorders, dysmenorrhea, and acute gout. The mechanism of action of the naproxen (naproxen sodium, NAPROSYN®), like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2).

Curator's Comment: Naproxen is a potent inhibitor of prostaglandin synthesis in vitro. Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models.

Sample Use Guides
Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis:
1 tablet of NAPROSYN® (250 mg or 375 mg or 500 mg) twice daily.
Acute Gout:
The recommended starting dose is 750 mg of NAPROSYN® followed by 250 mg every 8
hours until the attack has subsided.
Route of Administration:
Oral
There are data on the N-(3-methylpyridin-2-yl)amide derivatives of flurbiprofen and naproxen (Flu-AM1 and Nap-AM1, respectively) with respect to their properties towards fatty acid amide hydrolase (FAAH). Flu-AM1 and Nap-AM1 inhibited FAAH-catalysed hydrolysis of [(3)H]anandamide by rat brain homogenates with IC50 values of 0.44 and 0.74 uM. The corresponding values for flurbiprofen and naproxen were 29 and >100 uM, respectively.
