Use

Naproxen (Naprosyn, Anaprox), marketed as the (S)-enantiomer,is well absorbed after oral administration, givingpeak plasma levels in 2 to 4 hours and a half-life of 13 hours.Naproxen is highly protein bound and displaces most protein-bound drugs. It is recommended for use in RA, OA, acute gouty inflammation, and in primary dysmenorrhea. Itshows good analgesic activity (i.e., 400 mg is comparable to75–150 mg of oral meperidine and superior to 65 mg ofpropoxyphene and 325 mg of aspirin plus 30 mg of codeine).It is also available OTC as 200-mg tablets (Aleve).
