4 Propyphenazone
UNII OED8FV75PY - PROPYPHENAZONE

Propyphenazone is a pyrazolone derivative with anti-inflammatory, analgesic and antipyretic activity. 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.
