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. [PubChem]
Indication
Formerly widely used as an antipyretic and analgesic in rheumatism, neuritis, and common colds. Currently used to measure total body water.
Pharmacology
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. [Wikipedia]
Biochem/physiol Actions Antipyrine was found to be nonmutagenic when screened against Salmonella typhimurium tester strains TA100, TA98, TA97, TA102 and TA104.3 Application Oxidation by Fe(VI) has potential to remove N-nitrosodimethylamine precursors, including 4-dimethylaminoantipyrine, from drinking water.1 4-Dimethylaminoantipyrine is itself an effective scavenger of reactive nitrogen compounds nitric oxide and peroxynitrite, important in the inflammatory response.2
A pyrazolone that is 1,2-dihydro-3H-pyrazol-3-one substituted by a dimethylamino group at position 4, methyl groups at positions 1 and 5 and a phenyl group at position 2. It exhibits analgesic, anti-inflammatory, and antipyretic properties.
