Resumo
The number of pharmaceutical products currently on the market incorporating microparticles is considerable, and a strong increase is expected. Microencapsulation can fulfill several different objectives, such as to control the release rate of bioactive compounds, mask taste, or convert liquids into the solid form. This article presents a review of the technique, focusing its application on the development of controlled release oral forms. The characteristics of the compound encapsulated, the properties of the coating material, and different processes to carry out microencapsulation are analysed.
