Abstract

Un método para producir una formulacion farmacéutica microencapsulada que comprende hacer que un tinte se una a la superficie de partículas farmacéuticas o una fuente de energía radiante al tinte en presencia de material polimérico o polimerizable líquido ara hacer que el material se reticule, producir una conformacional de polímero reticulado en las superficies particulares. De manera preferible, el polímero proporciona una capa inmunoprotectora alrededor de las partículas, toda vez que los componentes farmacéuticos salgan de las microcápsulas. También se describen las formulaciones farmacéuticas microencapsuladas y su uso médico, especialmente para el tratamiento de las diabetes encapsulando células que secretan insulina.
