The present study evaluated whether Biopolymers are valid for microparticles by double emulsion method (A1/O/A2) - evaporation of the solvent, specific methods for the microencapsulation of water-soluble drugs. The ability of each to obtain microparticles were evaluated through the appearance of microparticles (MP) and efficiency of the process. We performed an optimization of the method used in the development of MP, assessing the possible influence of formulation and technological factors in the appearance and size of the MP. With the optimized method developed biodegradable microparticles containing a water-soluble drug, capable of controlling the release of drug for at least a week and can be administered via parenteral injection. The microparticles obtained were characterized by determining the appearance and size, processor performance, amount of drug encapsulation (load) and transfer in vitro test. In general, all employees can get Biopolymers MP. The appearance and performance of the process of encapsulation varies with the polymer used. The concentration of surfactant in the external aqueous phase and the process of extraction-evaporation of the solvent significantly affect the appearance of MP obtained. All MP presented a size suitable for parenteral administration. With 3 of the polymers were studied 7 MP to obtain a load suitable for a comfortable administration of a weekly dose of water-soluble drug.
