The Introductction of Piroxicam
Naproxen is a white crystalline or crystalline powder. Melting point 155.3℃. Soluble in acetone, soluble in methanol, ethanol, glacial acetic acid, insoluble in benzene, almost insoluble in water. Gradual color change when exposed to light, odorless, tasteless.
Naproxen is a non-steroidal anti-inflammatory drug, PG synthase inhibitor, can inhibit prostate synthase, has significant analgesic and antipyretic effects, oral absorption is completely rapid, plasma concentration peaks 2 to 4 hours after 1 administration, more than 99% in the blood and plasma protein binding, t1/2 for 13-14 hours, about 95% from the urine in its original form and metabolites excreted. Clinically used for the treatment of rheumatic and rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout, arthritis, tenosynovitis. It is also used to relieve pain due to musculoskeletal sprains, contusions, injuries, and dysmenorrhea.
