title: Pharmacokinetics of targeting with liposomes.
abstract: The optimization of drug disposition in the body leads to an increase in its therapeutic effect and to a decrease in adverse effects. Liposomes can serve as a potential drug carrier for achieving this. However, the behavior of a drug carrier system under in vivo conditions is complex. Therefore, a more complete understanding of the pharmacokinetics of liposomes themselves, as well as that of the encapsulated drug, is required. The optimization of the pharmacokinetics of liposomes can be performed by linking a pharmacodynamic model of the free drugs that are encapsulated into liposomes. Sensitivity analysis was applied to optimize the delivery system to maximize the antitumor effect of liposomal doxorubicin (DOX). Advanced technology for ligand-mediated selective targeting and intracellular targeting is also introduced for antitumor agents and for gene delivery systems.
