Propyphenazone is a pyrazolone - derivative and is used as non-steroidal anti-inflammatory drug , anti-pyretic and analgesic used. It was brought onto the market in 1933 by Hoffmann-La Roche as Saridon ® (in combination with phenacetin , pyrithyldione and caffeine ; no longer available in Germany).
pharmacology
Propyphenazone inhibits the production of prostaglandins and thus reduces the pain and inflammatory reactions . It dampens the processing and sensation of pain in the brain . The fever-lowering effect comes about by influencing the temperature control center in the brain. It is only weakly anti-inflammatory and has a slight antispasmodic effect, which can be beneficial for headaches.

There is no evidence of interactions with other drugs.
