Ampyrone is a metabolite of aminopyrine with analgesic, anti-inflammatory, and antipyretic properties.[2] While the parent drug, aminopyrine, has been discouraged due to the risk of agranulocytosis,[3][4] ampyrone itself has significantly lower toxicity.[5] It is used as a reagent for biochemical reactions producing peroxides or phenols.[2] Ampyrone stimulates liver microsomes and is also used to measure extracellular water.[2]
