Abstract

LA PRESENTE INVENCION PUEDE FORMAR UNA DISPERSION SOLIDA AMORFA DE CLORHIDRATO DE EFONIDIPINAQUE TIENE UNA ELEVADA ABSORCION INTESTINAL Y QUE PUEDE OBTENERSE SOMETIENDOSE UNA MEZCLA, QUE CONTIENE CLORHIDRATO DE EFONIDIPINADE FORMULA (I), HIDROXIPROPILMETILCELULOSA ACETATO SUCCINATO Y, OPTATIVAMENTE, UN TERMOESTABILIZADOR, A UNA ETAPA A DE TRATAMIENTO TERMICO A UNA TEMPERATURA DE 85 A 140G C, O TRATAMIENTO MECANOQUIMICO DE 0 A 140G C Y ACTO SEGUIDO A UNA ETAPA B DE TRATAMIENTO DE INMERSION EN UNA SOLUCION QUE CONTIENE AGUA, TRATAMIENTO DE IMPREGNACION CON UNA SOLUCION QUE CONTIENE AGUA O TRATAMIENTO DE CONTACTO CON UN GAS QUE CONTIENE VAPOR DE AGUA; O TRATAR LA MEZCLA ARRIBA MENCIONADA CON UNA CORRIENTE CALIENTE DE 100 A 140G C Y A PRESION ELEVADA. ADEMAS, EN LA ETAPA A ARRIBA MENCIONADA, LA MEZCLA SE SOMETE A CALENTAMIENTO DE ALTA FRECUENCIA, PERMITIENDOLE ASI PROPORCIONAR UNA DISPERSION SOLIDA DE CLORHIDRATO DE EFONIDIPINACON UNA ELEVADA ABSORCION INTESTINAL SIN NECESIDAD DE ACUDIR A LA ETAPA B. ESTE PROCESO ES MUY ADECUADO PARA LA PRODUCCION, YA QUE NO SE EXIGE EL USO DE UN DISOLVENTE ORGANICO.
