Description

Application

Analgesic.

Acetaminophen has been used:

• as an anti-inflammatory drug to test its effect in lipid peroxidation in marine mussels[1]
• to test its effect on neurite outgrowth in gamma-aminobutyric acid-ergic and glutamatergic neurons[2]
• as a hepatocellular injury inducing agent in mice[3]

Biochem/physiol Actions

Acetaminophen or paracetamol is an inhibitor of prostaglandin synthesis. It is complexed with arachidonic acid in central nervous system resulting in the formation of N-arachidonoylphentolamine, which is essential for the activation of cannabinoid receptor.[4] Acetaminophen is metabolized to toxic N-acetyl-p-benzoquinone imine. Paracetamol is prescribed for osteoarthritis pain and inhibits cyclooxygenase 1 and 2 activities.[5] It is metabolized by the cytochrome P450 enzymes in liver and is implicated in liver toxicity.[6]

General description

Acetaminophen or paracetamol is an analgesic and antipyretic.[4] It is however a weak non opioid analgesic.[6]
