^NY (what is this?) (verify)

Azapropazone is a nonsteroidal anti-inflammatory drug (NSAID). It is manufactured by Goldshield under the tradename Rheumox.^[1]

It was available in the UK as a prescription-only drug, with restrictions due to certain contra-indications and side-effects.^[2] Azopropazone has now been discontinued in the British National Formulary.

Azapropazone has a half-life of approximately 20 hours in humans and is not extensively metabolized.^[3]
