Application:
Valdecoxib (CAS: 181695-72-7) is a second-generation COX-2 inhibitor, developed as a follow-up to celecoxib for the oral once-daily treatment of osteoarthritis, adult rheumatoid arthritis and menstrual pain. Valdecoxib is approximately 28,000-fold more selective against human recombinant COX-2 than human recombinant COX-1. In an ex viva human whole blood assay, the I&O values against COX-2 and COX-1 were respectively 0.89 PM and 25.4 FM. In animal models, valdecoxib possesses excellent oral activity as an antiinflammatory. In rats, valdecoxib potently inhibited carrageenan footpad edema and adjuvant-induced arthritis. Valdecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits anti-inflammatory, analgesic and antipyretic properties in animal models. It is a potent and selective inhibitor of prostaglandin synthesis primarily through inhibition of COX-2. Valdecoxib is used to relieve some symptoms caused by arthritis (rheumatism), such as inflammation, swelling, stiffness, and joint pain. Valdecoxib is approved for the relief of the signs and symptoms of osteoarthritis and adult rheumatoid arthritis and for the treatment of primary dysmenorrhea. Valdecoxib is contraindicated for the treatment of postoperative pain immediately following coronary artery bypass graft surgery.Sufficient Capacity: Sufficient facilities and technicians
