What is Flunixin?

Plain description, key identifiers and synonyms

Flunixin is a pyridinemonocarboxylic acid that is nicotinic acid substituted at position 2 by a 2-methyl-3-(trifluoromethyl)phenylamino group. A relatively potent non-narcotic, nonsteroidal analgesic with anti-inflammatory, anti-endotoxic and anti-pyretic properties, used in veterinary medicine (usually as the meglumine salt) for treatment of horses, cattle and pigs. 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 pyridinemonocarboxylic acid, an organofluorine compound and an aminopyridine. It is functionally related to a nicotinic acid. It is a conjugate acid of a flunixin(1-).
