"MICROSPHERES – “A NOVEL TREND IN DRUG DELIVERY SYSTEM”
Journal Title: World Journal of Pharmaceutical and Medical Research - Year 2017, Vol 3, Issue 2
Abstract
In the current scenario targeted drug delivery requires an efficient drug carrier which can deliver the drug specifically on the site of action in a sustained and controlled manner. Among many such carriers, microspheres fulfil all the parameters for a potent drug carrier. Microspheres are one of the multiparticulate delivery system which is prepared to obtain prolonged or controlled drug delivery. Microspheres are defined as free flowing powders of spherical shape, consisting of proteins or synthetic polymers, which are either biodegradable or nonbiodegradable in nature and ideally having a particle size ranging from 1–1000 μm. The internal structure of the microspheres can vary as a function of the microencapsulation process employed. Controlled drug release from microspheres occurs by diffusion of the drug through a polymeric excipient, diffusion of the entrapped drug through the pores in the polymeric microspheres.
