Abstract

PROCEDIMIENTO PARA PREPARAR UNA DISPERSION SOLIDA DE UNA DIHIDROPIRIDINA FARMACOLOGICA. COMPRENDE: A) DISOLVER LA DIHIDROPIRIDINA ACTIVA CON UNA CONCENTRACION DEL 80% EN PESO, EN UNA MATRIZ LICUADA DE POLIALQUILEN-GLICOL, A UNA TEMPERATURA ENTRE 50 Y 85JC; B) TRANSFORMAR LA DISPERSION EN FORMA SOLIDA; C) GRANULAR LA FORMA SOLIDA EN FORMA DE GRANOS; Y D) CRISTALIZAR LA DIHIDROPIRIDINA ACTIVA EN LOS GRANOS, PARA OBTENER UNA ESTRUCTURA UNIFORME. LA DIHIDROPIRIDINA SE ELIGE ENTRE ESTER ETILICO DE ACIDO 4-(2,1,3-BENZOXADIAZOL-4-IL)-1,4-DIHIDRO-5-ETOXI-CARBOCIL-2,6-DIMETIL-3-PIRIDINA-CARBOXILICO Y ESTER DE ISOPROPILO DE ACIDO 4-(2,1,3-BENZOXADIAZOL-4-IL)-1,4-DIHIDRO-5-METOXICARBOCIL-2,6-DIMETIL-3-PIRIDINA CARBOXILICO. SE UTILIZA PARA TRATAR LA ANGINA DE PECHO.
