What is Tenoxicam?

Plain description, key identifiers and synonyms

Tenoxicam is a thienothiazine-derived monocarboxylic acid amide obtained by formal condensation of the carboxy group of 4-hydroxy-2-methylthieno[2,3-e][1,2]thiazine-3-carboxylic acid 1,1-dioxide with the amino group of 2-aminopyridine. Used for the treatment of pain and inflammation in osteoarthritis and rheumatoid arthritis. It is also indicated for short term treatment of acute musculoskeletal disorders including strains, sprains and other soft-tissue injuries. It has a role as a non-steroidal anti-inflammatory drug, a non-narcotic analgesic, an antipyretic and an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor. It is a member of pyridines, a monocarboxylic acid amide, a thienothiazine and a heteroaryl hydroxy compound.
