Abstract

Drug targeting with liposomes has been studied for over 25 years and has demonstrated its value in clinical practice. This mini review offers an overview of the design and application of liposomes for i.v. drug targeting. Two approaches are outlined: passive and active targeting. The former approach is based on liposomes with prolonged circulation and selective target localization properties, while in the latter approach specific targeting ligands are coupled to the liposome surface in order to achieve enhanced interaction with target cell membranes.
