Abstract

LA PREPARACION DEL SISTEMA NANOVESICULAR SE CARACTERIZA, SEGUN EL INVENTO, PORQUE: (1) SE PREPARA UNA FASE LIQUIDA CONSTITUIDA BASICAMENTE POR UNA SOLUCION DE CICLODEXTRINA MODIFICADA POR GRUPOS ACILO Y DE UN ACEITE EN UN DISOLVENTE O MEZCLA DE DISOLVENTES ORGANICOS(S); (2) SE PREPARA UNA SEGUNDA FASE LIQUIDA CONSTITUIDA BASICAMENTE DE AGUA O MEZCLA ACUOSA, PUDIENDO CONTENER UNO O VARIOS AGENTES TENSOACTIVOS, PUDIENDO A UNA DE LAS FASES (1) Y (2) AÑADIR UNA MOLECULA ACTIVA; (3) SE AÑADE BAJO AGITACION MODERADA UNA DE LAS FASES LIQUIDAS OBTENIDAS POR (1) O (2) A LA OTRA, DE MODO QUE SE OBTENGA PRACTICAMENTE AL INSTANTE UNA SUSPENSION COLOIDAL DE NANOCAPSULAS DE CICLODEXTRINA MODIFICADA QUE CONTIENE ACEITE Y EVENTUALMENTE LA MOLECULA ACTIVA. EN CASO CONTRARIO, SE ELIMINA TODO O PARTE DEL DISOLVENTE O MEZCLA DE DISOLVENTES Y DEL AGUA O MEZCLA ACUOSA. SE APLICA A LOS VECTORES DE PRODUCTOS FARMACEUTICOS, COSMETICOS, QUIMICOS, ETC.
