ABSTRACT

Microspheres are characteristically free flowing biodegradable in nature and ideally having a particle size less than 200 μm. A well designed controlled drug delivery system powders consisting of proteins or synthetic polymers which are overcome some of the problems of conventional therapy and enhance the therapeutic efficacy of a given drug. There arecan overcome some of the problems of conventional therapy and enhance the therapeutic efficacy of a given drug. There are various approaches in delivering a therapeutic substance to the target site in a sustained controlled release fashion. One such approach is using microspheres as carriers for drugs. It is the reliable means to deliver the drug to the target site with specificity, if modified, and to maintain the desired concentration at the site of interest without untoward effects. Microspheres received much attention not only for prolonged release, but also for combining various other strategies, microspheres will find the central place in novel drug delivery, particularly in diseased cell targeting of anticancer drugs to the tumour. In future by sorting, diagnostics, gene & genetic materials, safe, targeted and effective in vivo delivery and supplements as miniaturesorting, diagnostics, gene & genetic materials, safe, targeted and effective in vivo delivery and supplements as miniature.
