Abstract

Procedimiento de obtención de ciclosporina A mediante secado por asperción, modificando su solubilidad en agua y en fluido gastrointestinal con ayuda de un tensoactivo hidrofílico y uso de una mezcla de excipientes como Dextrana y polietilenglicol 4000 para aumentar su estabilidad en agua, contribuyendo a mantenerla estable en agua por más de 24 horas, lo que coadyuva a mejorar la absorción de la misma.Procedure for obtaining cyclosporin A by spray drying, modifying its solubility in water and gastrointestinal fluid with the help of a hydrophilic surfactant and using a mixture of excipients such as Dextrana and polyethylene glycol 4000 to increase its stability in water, contributing to keep it stable in water. water for more than 24 hours, which helps to improve its absorption.
