Celecoxib

Celecoxib is a selective COX-2 inhibitor NSAID that reduces prostaglandin-mediated pain and inflammation while sparing gastric mucosal COX-1, used for osteoarthritis, rheumatoid arthritis, acute pain and familial adenomatous polyposis. Simson Pharma's Celecoxib reference standard and impurities support the high-volume stability-indicating testing this major oral NSAID requires.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Celecoxib Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
