Solvent evaporation as a imposing method for microencapsulation - A review

Abstract

Microencapsulation is a process from which solid, liquid or even gaseous particles are coated with a continuous film of polymeric material, having a diameter in range of 1 to 1000 μm and are widely used as drug carriers. The goal of writing this review on microencapsulation by solvent evaporation technique was to combine the recent literature with special focus on solvent evaporation technique for microencapsulation of pharmaceuticals that have recently become leading investigated technologies in the field of drug delivery development. In order to understand the microencapsulation by solvent evaporation technique, the basics point was summarized. Afterwards, we have reviewed various solvent evaporation techniques designed and developed until now. Finally, various potential factors influencing microencapsulation by solvent evaporation technique were covered in detail.

Key words: microencapsulation, Solvent evaporation, Variables, Drug delivery
