Abstract
Formas cristalinas polimórficas del antibiótico rifaximina (INN) denominadas rifaximina a y rifaximina b y una forma pobremente cristalina denominada rifaximina g. Estas formas son de utilidad en la producción de preparaciones medicinales para uso por vía oral y tópica y se pueden obtener por medio de un proceso de cristalización llevado a cabo por disolución en caliente de la rifaximina cruda en alcohol etílico y por cristalización del producto mediante la adición de agua a una temperatura determinada y por un período de tiempo determinado. La cristalización es seguida de un secado llevado a cabo bajo condiciones controladas hasta alcanzar un contenido de agua específico en el producto final. Reivindicación 1: Una rifaximina alfa purificada, un polimorfo del antibiótico rifaximina, caracterizada porque dicha rifaximina alfa presenta un contenido de agua menor que un 4,5% y produce un difractograma de polvo por rayos X que presenta picos en valores de ángulos de difracción 2theta de 6,6s, 7,4s; 7,9s; 8,8s; 10,5s; 11,1s; 11,8s; 12,9s; 17,6s; 18,5s; 19,7s; 21,0s; 21,4s; 22,1s. Reivindicación 6: Un proceso para la producción de las rifaximinas alfa, beta y gamma, caracterizado porque comprende: hacer reaccionar un equivalente molar de rifaximina O con un exceso de 2-amino-4-metilpiridina en una mezcla de solventes compuesta de agua y alcohol etílico en una relación volumétrica que comprende entre 1:1 y 2:1, por un período de tiempo entre 2 y 8 horas, a una temperatura entre 40sC y 60sC, tratar la masa de reacción a temperatura ambiente con una solución de ácido ascórbico en una mezcla de agua, alcohol etílico y ácido clorhídrico acuoso concentrado, ajustar el pH de la masa de reacción en pH 2,0 con una solución acuosa concentrada de ácido clorhídrico, filtrar la suspensión, lavar todo sólido resultante con la mezcla de solventes de agua/alcohol etílico para obtener una rifaximina cruda, purificar la rifaximina cruda por disolución de la misma en alcohol etílico a una temperatura que comprende entre 45sC y 65sC, hacer precipitar la rifaximina cruda por adición de agua y por disminución de la temperatura de la suspensión a un valor entre 0sC y 50sC bajo agitación por un período de tiempo entre 4 y 36 horas, filtrar la suspensión, lavar el sólido resultante con agua, y secarlo bajo vacío o bajo condiciones de presión normal, con o sin un agente de secado, a una temperatura entre temperatura ambiente y 105sC, por un período de tiempo entre 2 y 72 horas.
