Popis: The aim of this study was to evaluate the pharmacokinetics and tissue distribution of the glycyrrhetinic acid (GA) liposome modified with galactosylated lipid (NOH-GA-LP), compared with GA conventional liposome (GA-LP) and GA solution in mice. The pharmacokinetics and biodistribution of liposomal and solution formulation of GA in mice were studied after intravenous administration. Plasma and tissues were treated using liquid-liquid extraction and determined using reversed-phase high-performance liquid chromatography. Results showed that the mean residence times of NOH-GA-LP (2.99-fold) and GA-LP (2.94-fold) were higher than that of the GA solution in plasma. NOH-GA-LP produced a drug concentration in the liver that was markedly higher than that in other tissues and was approximately 2.0- and 4.8-fold of that of GA-LP and GA solution, respectively. In conclusion, the NOH-GA-LP prepared in this study is a promising sustained-release and drug-targeting system for antitumor drugs.
