Biological Activity

Description Amfenac Sodium monohydrate is a non-steroidal analgesic anti-inflammatory drug with acetic acid moiety. The IC50 values for COX1 and COX2 is 250 nM and 150 nM, respectively.
Targets
COX-2 [1] COX-1 [1]
150 nM 250 nM
In vitro Amfenac is a potent inhibitor of both COX-1 and COX-2 with IC50 of 0.25 and 0.15 μM. [1]
In vivo Amfenac possesses both antipyretic and analgesic properties in vivo. Amfenac (4 mg/kg) suppressed acute (Evans blue-carrageenan pleural effusion) and chronic (adjuvant-induced arthritis) inflammation by 33% and 28%, respectively, which is 16.4 and 22.8 times more potent than phenylbutazone. The analgesic activity of Amfenac is 43 times that of acetylsalicylic acid in the Randall-Selitto assay, and 156 and 56.3 times more potent than phenylbutazone in the acetylcholine-induced abdominal constriction in mice and in the bradykinin-induced nociceptive response in dogs, respectively. Amfenac produces less gastric irritation than acetylsalicylic acid when applied topically to the exposed gastric mucosa of cats or when administered orally to rats and dogs. Upon subchronic oral administration to rats, the therapeutic ratio of Amfenac is twice that of phenylbutazone. [2]
