Piroxicam (US trade name Feldene) is a nonsteroidal anti-inflammatory drug used to relieve the symptoms of arthritis, primary dysmenorrhoea, pyrexia; and as an analgesic, especially where there is an inflammatory component. It is also used in veterinary medicine to treat certain neoplasias expressing cyclooxygenase (COX) receptors, such as bladder, colon, and prostate cancers.

Mechanism of action

Piroxicam is an NSAID and, as such, is a non-selective COX inhibitor.
