Piroxicam is one of the important therapeutic nonsteroidal anti-inflammatory class of drugs used mainly to suppress pain and inflammation in arthritis and other musculoskeletal disorders. Besides being anti-inflammatory, these drugs are analgesic and antipyretic often used for the relief of nonspecific fever condition. Recently, piroxicam has also gained attention as an effective therapy for tumors, colorectal, and invasive bladder cancers. The objective of the current study is to evaluate the protective effects of the alcoholic leaf extract of Hibiscus rosa-sinensis (AEH), Malvaceae, against piroxicam-induced toxicity in mice. Sixty adult Swiss albino mice (Mus musculus) were divided into four groups (n = 10), which included a control group, a group treated orally with AEH (30 mg kg(-1) b.w.) for 15 days, a group treated orally with piroxicam (6.6 mg kg(-1) b.w.) for 15 days, and another group treated orally with piroxicam and AEH for 15 days. The results indicated that treatment with piroxicam alone resulted in a significant increase in the activities of serum marker enzymes, namely, aspartate transaminase, alanine transaminase, and alkaline phosphatase with profound hepatic lipid peroxidation as evidenced by a marked increment in the level of thoibarbituric acid reactive substances along with a distinct diminution in reduced glutathoine content and various antioxidant enzymes such as superoxide dismutase, catalase, and glutathione peroxidase in the liver. However, treatment with AEH during piroxicam treatment retrieved or partially antagonized the effects induced by piroxicam toward the normal values of controls. Histopathological observations also corroborate with the above findings. It can be concluded that AEH exhibited a protective action against piroxicam toxicity and effective in combating oxidative stress-induced hepatic damage.
