ABSTRACT

Microencapsulation are multi-particulate drug transport classifications, prepared to get extended, sustained or controlled drug delivery to increase bioavailability, stability and target the drug, to exact site at a preset rate. Every minute droplets or particles of liquid or solid material that are surrounded or coated with a continuous film of polymeric material is known as microencapsulation process. Microencapsulation techniques used to improve stability, cover unpleasant taste, improve the release properties of drugs, and deliver specific drug delivery in pharmaceutical industries. The contest of microencapsulation is in selecting the suitable conditions for producing extremely active microcapsules. This paper is a complete review of microencapsulation and its applications, various drug release mechanisms and latest developments in the pharmacy field. It provides an inclusive overview of technology, main goals of microencapsulation and discusses the various processes and techniques involved in microencapsulation including physical, chemical, physicochemical, and other methods involved.

Keywords: Microencapsulation, Release Mechanisms, Preparation techniques, Applications.
