Acetaminophen (paracetamol) is a selective cyclooxygenase-2 (COX-2) inhibitor with IC50 of 25.8 μM, It is a widely used antipyretic analgesic[1].

Paracetamol (50 mM) significantly reduces cell viability. But co-treatment with acetaminophen and HV110 can significantly increase cell viability[2].

Paracetamol (250 mg / kg) reduces glutathione levels and glutathione peroxidase activity in mice, and induces mast cell death and hypertrophy in primary mouse liver cells The inhibitor ferrostatin-1 can block this effect. Paracetamol has analgesic and antipyretic effects in animal models.
