Efficacy and Safety Study of Magnesium Isoglycyrrhizinate Injection in Subjects With Acute Drug-induced Liver Injury

The pharmacology research shows that Magnesium Isoglycyrrhizinate could significantly decrease the elevation of ALT and AST coursed by carbon tetrachloride, D-galactosamine and Thioacetamide. It could also significantly reduce the injury on the liver coursed by D-galacosamine and immunologic factors. Magnesium Isoglycyrrhizinate with strong anti-inflammatory effect could protect the liver cell and improve the liver function.
