Drug metabolism and transport mediated the hepatotoxicity of Pleuropterus multiflorus root: a review.

Abstract

Pleuropterus multiflorus root (PMR, Polygoni Multiflori Radix) is an herbal medicine widely used in East Asia, particularly China. However, the potential hepatotoxicity has hindered its rational and safe application of PMR in clinical practice. Recently, the hepatotoxic study of PMR have made great progress, especially drug metabolism and transport-mediated liver injury. In this review, we summarized the advancement of drug metabolism and transport regluated hepatic injury of PMR, pointed out the key role of drug metabolizing enzymes and transporters in regulating hepatic injury of PMR, and emphasized the main hepatotoxic substances, toxicity promoter, and hepatic toxic substance-toxicity promoter interactions in PMR. On this basis, the clinical prospect of preventing and treating hepatic injury of PMR from the perspective of metabolism and transporter was discussed, to provide a useful reference and theoretical basis for the prevention and treatment of hepatic injury of PMR.
