Evidence & regulatory context
- Mechanism
- Cyclooxygenase inhibitor (target CHEMBL2094253); FAAH inhibitor (CHEMBL2243), which also generates the active metabolite AM404; AM404 opens the vanilloid receptor TRPV1 (CHEMBL4794). Black box warning (hepatotoxicity). Mannitol is the co-formulated excipient/stabiliser in the paracetamol-mannitol injection.

RatCrushLimb / muscle crushSprague-DawleyMalen = 36 rats in six groups of sixIntraperitonealAcetaminophen 100 mg/kg; mannitol 1 g/kg
Model: Crush injury produced by compression of the gastrocnemius muscle region for 2 or 24 hours
No significant differences in sodium, potassium, alanine aminotransferase or creatinine clearance between treatment groups, but acetaminophen reduced histopathological renal damage more than mannitol, with the combination intermediate.

Model: Spared nerve injury of the left hind limb with ligation and section of the common peroneal and tibial nerves, sural nerve spared
Paracetamol at 300 mg/kg increased anxiety-like behaviour and anhedonia and impaired recognition memory in unoperated rats, while 50 mg/kg reduced mechanical hypersensitivity and anxiety in nerve-injured rats.
