INTRODUCTION: Isoniazid (INH) and rifampicin (RIF), the most common anti-tubercular therapy, causes hepatotoxicity through a multi-step mechanism in certain individuals. The present study was an attempt to evaluate the hepatoprotective effect of coenzyme Q10 against INH + RIF-induced hepatotoxicity in Wistar albino rats.

METHODS: Hepatotoxicity was induced by the oral administration of INH + RIF (50 mg/kg b.w. each/day) in normal saline water for 28 days. The hepatoprotective effect of coenzyme Q10 (10 mg/kg b.w./day) was compared with that of the standard drug silymarin (25 mg/kg b.w./day). Animals were sacrificed at the end of the study period, and blood and liver were collected for biochemical, immunological and histological analyses.

RESULTS: Evaluation of biochemical parameters showed that coenzyme Q10 treatment caused significant (P < 0.05) reduction in the elevated levels of serum liver function markers and restored normal levels of total protein, albumin and lipids in INH + RIF-treated rats. Also, it was observed that coenzyme Q10 was able to restore normal levels of enzymic antioxidants, reduced glutathione and lipid peroxidation in the INH + RIF-treated rats. Coenzyme Q10 was found to effectively reduce the extent of liver damage caused due to INH + RIF. In addition, the levels of IL-10 and IL-6 were significantly elevated in the INH + RIF-induced rats treated with CoQ10.

CONCLUSION: Our study indicates the protective role of coenzyme Q10 in attenuating the hepatotoxic effects of INH + RIF in a rat model and that it could be used as a food supplement during anti-tubercular therapy.
