Propyphenazone
An analgesic and antipyretic of the pyrazolone family, derived from phenazone: patented in 1931 and introduced in 1951 for rheumatic disorders, it is also used with paracetamol and caffeine for headache. This family brings together the active ingredient and pharmacopoeial impurities.
