Gastroretentive Drug Delivery through Natural Mucilage Based Microspheres: A Concise Review

Abstract

The use of novel drug delivery systems for efficient delivery of drug is recently explored area. Several novel drug delivery systems have been proved to be effective in delivery of drug. Many scientific experts have showed efficacy of novel drug delivery systems in animal models. The carrier mediated drug delivery involves use of various drug loaded carriers like nanoparticles, microparticles, microspheres, microsponge, liposomes, ethosomes, transfersomes, phytosomes and glycerosomes. The microspheres are micron sized drug loaded spherical particles. The use of natural gums and mucilage for fabrication of drug loaded microspheres is recently explored area for gastrorentive drug delivery. Thus, present review highlights use of these natural mucilage based microspheres for fabrication of drug loaded microsphere.
