Abstract: AIM: To study the distribution characteristics and liver targeting trend of adriamycin-loaded chitosan nanoparticles surfacemodified with glycyrrhizin (GL-ADM-NPs) in mice.METHODS: The GL-ADM-NPs, adriamy cin-loaded chitosan nanoparticles (ADMNPs), and free adriamycin solution (F-ADM) were intravenously administered to mice, respectively.The LC/MS/MS method was used to determine the concentrations of Adriamycin in mice plasma, heart, liver, spleen, lung and kidney. The targeting efficiency was evaluated by targeting parameters (Re and Ce).RESULTS: Compared with F-ADM, ADM-NPs obviously increased the adriamycin concentration in the liver, Re and Ce were 3.54 and 2.2, respectively. After modified with glycyrrhizin on the nanoparticle surface, G L-ADM-NPs showed a higher targeting efficiency in the liver.The Re and Ce were 5.83 and 3.42, respectively.The levels of GL-ADM-N Ps in the heart and kidney tissues were sig nificantly decreased. The AUC were 43.06 % and 62.58 % of the values of F-ADM. CONCLUSION: GL-ADM-NPs changes the tissue distribution of ADM, has the liver targeting effect, and might decrease the side effects of ADM.It will be a promising carrier to deliver ADM to liver.
