Backgrounds: This study was conducted to establish olanzapine-induced hepatopathy in Wistar albino rats as a newer model to screen putative hepatoprotective agents namely silymarin. Materials and Methods: Albino rats were divided into three groups, namely vehicle control group (CG), olanzapine-treated group (OZ), and olanzapine plus silymarin (OZS) treated groups. Both the OZ and OZS groups were treated with the same dose of intraperitoneal olanzapine for 6 weeks and group OZS additionally received oral silymarin. Baseline and terminal hepatic enzymes (SGOT, SGPT, and ALP) were measured in all three groups. Results: Histopathological examination of livers of both OZ and OZS groups showed degenerative changes, whereas those of control group showed normal architecture. Liver enzyme levels showed statistically significant rise in comparison to the control group as well as the respective base line values in both the test groups, but the differences in the rise of liver enzymes between the two test groups were not statistically significant. Conclusion: Olanzapine-induced hepatopathy in rats can be used as a model for screening putative hepatoprotective agents and in our setting silymarin has failed to provide any hepatoprotection.
