A B S T R A C TObjectives: To evaluate the toxicity of lisinopril in liver of male rats and its reversal effect of garlic capsule (GAR) and selenium-vitamin A, vitamin B, vitamin C (SACE). Methods: Thirty five adult male wistar rats were randomly assigned into 5 groups of 7 animals per group. Group I serves as the control, animals in Groups II, III, IV and V received 28 mg/kg body weight of lisinopril via oral route. Group III was co-treated with GAR at therapeutic dose of 250 mg/kg body weight per day. Group IV was co-treated with SACE at dose of 500 mg/kg body weight. Lastly, group V was co-treated with GAR and SACE at doses of 250 and 500 mg/kg body weight respectively, and the experiment last for 8 days.Results: Administration of lisinopril caused systemic toxicity in liver as well as adverse histopathologic changes in the tested tissue. While GAR and SACE significantly (P < 0.05) reversed the toxic effects induced by lisinopril. Conclusions: Collectively, the results suggest that therapeutic dose of lisinopril elicits toxicity in male rats through induction of oxidative damage and depletion of cellular adenosine triphosphate. The reversal effects of GAR and SACE during lisinopril treatment suggest that these antioxidants may find clinical application in cellular damage involving ROS and adenosine triphosphate.

We therefore concluded that the combination of GAR and S-VACE can be a novel therapy for the management of lung diseases in humans.
