Microencapsulation: Techniques, Polymers, Pharmaceutical Application

Microencapsulation technology is advancing rapidly because of its extensive applications in many industries including graphics, food, agriculture and especially pharmaceutical and medical fields. Microparticulate delivery systems in pharmaceutical science make it possible to prepare stable formulations of sensitive drug substances, eliminate incompatibilities, mask unpleasant tastes or odors and facilitate the handling of toxic materials. In addition, microparticles play an important role in the development of controlled- or prolonged-release dosage forms, as well as in developing drug delivery systems that improve the bioavailability of conventional drugs and minimize their side effects. The pharmaceutical applications of microparticles entail different routes of administration including oral, pulmonary, nasal, ocular and parenteral delivery.
