Advances in pulmonary delivery of nanoparticles

Abstract

Nanotechnology has potential in the development of novel and effective delivery of drugs within lungs. Different strategies have been utilized for pulmonary delivery of drugs, including the use of lipid-based delivery systems (liposomes, ISCOMs, SLNs), use of polymeric matrix (PLGA, poly caprolactone, cynoacrylates, gelatin), development of polysaccharide particulates (chitosan, alginates, Carbopol, etc.), biocompatible metallic inorganic particles (iron, gold, zinc), etc. This paper reviews various nanopaticulate approaches in the form of lipids, polymers, metals, polysaccharides, or emulsions based for pulmonary drug delivery that could provide an increased biological efficacy and better local and systemic action. © 2012 Informa Healthcare USA, Inc.
