Application of nanogel systems in the administration of local anesthetics

Abstract

Nanogels are robust nanoparticles that could be used to deliver active drug compounds in controlled drug delivery applications. This review discusses the design, synthesis, loading, and release of local anesthetics using polymeric nanoparticles produced via various types of polymerization techniques. The strategy of using layer-by-layer approach to control the burst release of procaine hydrochloride (PrHy; a local anesthetic drug of the amino ester group) is described and discussed. ©2010 Tan et al, publisher and licensee Dove Medical Press Ltd.
