Propyphenazone, a pyrazolone derivative with anti-inflammatory,
analgesic and antipyretic activity, was introduced in 1951 for the treatment of
rheumatic disorders. As it is structurally related to aminophenazone it has been
associated with severe blood dyscrasias. However, it cannot be transformed into
potentially carcinogenic nitrosamines and has therefore been widely used as a
replacement drug for aminophenazone. In certain countries, products containing
propyphenazone have now been restricted in their indications, whereas in others
they are still available, sometimes as over-the-counter preparations. See also WHO
comment for aminophenazone. | [Clinical Use]
Propyphenazone is a
derivative of phenazone and has a similar analgesic
and antipyretic action. It is used as a monocompound
as well as in multi-ingredient preparations. | [References]
