Acetaminophen (APAP) is a widely consumed drug for pain management and treatment of pyrexia. However, beyond its recommended dose, it becomes harmful for health and may induce acute liver dysfunction. Current work is designed to ameliorate the APAP induced liver toxicity which was induced in rats by giving intra-peritoneal injection of APAP (800mg/kg) dissolved in 40% polyethylene glycol at day 1 and day 14. APAP dosed/intoxicated rats orally administered either with ethanol extract of Spatoglossum asperum (200mg/kg) and its fractions including n-hexane, chloroform and methanol soluble in a dose of 150mg/kg each daily for 14 days in their respective groups. APAP dosed rats showed remarkable elevation in hepatic biomarkers viz., alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenases, total bilirubin, pro-inflammatory cytokines interleukine-6 and apoptotic protein (caspase-3). In addition, hepatic oxidative stress (lipid per oxidation and indirect nitric oxide) and antioxidant biomarkers (glutathione peroxidase, catalase and reduced glutathione) were also altered. Whereas APAP dosed rats treated with ethanol extract of S. asperum and its fractions showed amelioration in concentration of hepatic enzymes, pro-inflammatory cytokines, apoptotic protein and reduction in hepatic oxidative stress by decreasing the lipid peroxidation, indirect nitric oxide and uplifting the activities of antioxidant enzymes and protein.
