Tumor delivery of macromolecular drugs based on the EPR effect

Vladimir Torchilin. Adv Drug Deliv Rev. .

Abstract

Enhanced permeability and retention (EPR) effect is the physiology-based principal mechanism of tumor accumulation of large molecules and small particles. This specific issue of Advanced Drug Delivery Reviews is summing up multiple data on the EPR effect-based drug design and clinical outcome. In this commentary, the role of the EPR effect in the intratumoral delivery of protein and peptide drugs, macromolecular drugs and drug-loaded long-circulating pharmaceutical nanocarriers is briefly discussed together with some additional opportunities for drug delivery arising from the initial EPR effect-mediated accumulation of drug-containing macromolecular systems in tumors.
