Antipyrine is an analgesic and antipyretic that has been given by mouth and as ear drops. It is often used in testing the effects of other drugs or diseases on drug-metabolizing enzymes in the liver. It inhibits cyclooxygenases and shows little anti-inflammatory activity. Like many old and approved substances after almost 100 years of use, antipyrine has been associated with some serious side effects, namely agranulocytosis and shock reactions.

In Vivo Use Guide

54 mg apply drops along the wall of the ear canal until filled and repeating every 3 hours for 24 hours unless the subject is sleeping.

Route of Administration: Otic (auricular)

In Vitro Use Guide

The influence of phenazone on the production of prostacyclin and thromboxane in human umbilical arteries was investigated by in vitro perfusion. With perfusate concentrations ranging from 10(-7) to 10(-4) M a decrease in the formation of both prostanoids was observed. The inhibitory effect of phenazone on prostanoid formation was found to be equal to that of indomethacin.
