| Naproxen Usage And Synthesis |
| Non-steroidal anti-inflammatory drugs |
Naproxen is a non-steroidal anti-inflammatory drug ,it is a PG synthase inhibitor, which can inhibit prostaglandin synthetase, it has significant analgesic and antipyretic effects, oral absorption is rapid and complete, 2 to 4 hours after a dose ,plasma concentration reaches the peak, in the blood , more than 99% is bound to plasma proteins, t1 / 2 is 13 to 14 hours, about 95% is discharged from the urine with the prototype and metabolites.it is clinically used For the treatment of rheumatic and rheumatoid arthritis , osteoarthritis, ankylosing spondylitis, gout, arthritis, tenosynovitis.it can also be used to alleviate pain caused by musculoskeletal sprains, contusions,damages and dysmenorrhea . But it should be noted that like other non-steroidal anti-inflammatory drugs, the same serious gastrointestinal adverse reactions could occur at any time while taking naproxen during treatment, so the active gastroduodenal ulcer patients are hanged, other gastrointestinal tract disease patients should take this drug under close medical supervision. The above information is edited by the Chemicalbook of Tian Ye. |
