Metabolite Identification
Common NameValdecoxib
DescriptionValdecoxib, also known as bextra or kudeq, belongs to the class of organic compounds known as benzenesulfonamides. These are organic compounds containing a sulfonamide group that is S-linked to a benzene ring. Valdecoxib is a drug which is used for the treatment of osteoarthritis and dysmenorrhoea. Valdecoxib is an extremely weak basic (essentially neutral) compound (based on its pKa).
