Antipyrine is an analgesic, a non-steroidal anti-inflammatory drug and an antipyretic.

Phenazone, also known as phenazon, antipyrine, or analgesine, is an analgesic, a non-steroidal anti-inflammatory drug and an antipyretic. It was first synthesized by Ludwig Knorr in 1883. It is formed by reducing diortho- dinitrodiphenyl with sodium amalgam and methyl alcohol, or by heating diphenylene-ortho-dihydrazine with hydrochloric acid to 150 °C. It crystallizes in needles which melt at 156 °C. Potassium permanganate oxidizes it to pyridazine tetracarboxylic acid. Phenazone has an elimination half life of about 12 hours.
