Aminopyrine as antipyretic analgesic anti-inflammatory drug pyrazole ketones, inhibit the synthesis of
prostaglandin E1 in the front of the hypothalamus neurons and release, to restore the normal reaction of the
temperature regulating center feeling neurons and antifebrile effect.
Amidopyrine also inhibit inflammation in local tissue of prostaglandin synthesis and release, stabilize
lysosomal membrane, influence the phagocytosis of phagocytic cells, and have anti-inflammatory effect.
 

Aminophenazone is a pyrazolone with analgesic, anti-inflammatory, and antipyretic properties but has risk
of agranulocytosis. 

A breath test with 13C-labeled aminopyrine has been used as a non-invasive measure of cytochrome
P-450 metabolic activity in liver function tests.
