4-Methylamino antipyrine (hydrochloride)

4-Methylamino antipyrine hydrochloride is an active metabolite of Metamizole. Metamizole is a pyrazolone non-steroidal anti-inflammatory drug (NSAID) and inhibits COX. Metamizole is an nonopioid analgesic agent and can be used for pain and fever[1][2][3]. 4-Methylamino antipyrine hydrochloride has analgesic, antipyretic, and relatively weak antiinflammatory properties[2].
