A Review on Microsphere
The microsphere is having free-flowing powder properties that are incorporate proteins and synthetic or natural polymer. This polymer is biodegradable in nature and particle size having less than 200 µm. Advanced drug delivery system has various advantages over the mainstream multi dose therapy. The microsphere's drug delivery systems are acceptable for attained delay or sustained release formulation with minimum risk of dose repeatability and small gastric habitation time. The present review provides a complete discussion of therapeutic aspects of the microsphere drug delivery system into deliberation of the required area for microparticulate, types of polymers used, method of preparation, type of microspheres in detail, parameters & targeting of microspheres & practical aspects of microspheres.
Keywords: Microspheres, bioavailability, types, classification, ideal properties, evaluation, etc.
