Abstract
Se proporcionan formas de dosificacion prolongada de estavudina que comprenden pequenas esferas o globulos formados por extrusion-formacion de pequenasesferas o globulos y recubiertos con un recubrimiento de sellado. Las pequenas esferas o globulos s e recubren también con un recubrimiento de liberacionmodificada de modo que una cápsula de gelatina rígida que contiene tales pequenas esferas o globulos proporcionará niveles en sangra de estavudina duranteaproximadamente 24 horas. Las pequenas esfe ras o globulos se preparan de una mezcla seca de estavudina, un agente formador de pequenas esferas o globulos, undiluyente adecuado y una cantidad estabilizadora de estearato de magnesio. El estearato de magnesio, en contraste con otros aditivos far macéuticos similares,se encontro que estabiliza a la estavudina contra la degradacion debido a hidrolisis en presencia de la cantidad limitada de agua necesaria para el proceso deextrusion-formacion de pequenas esferas o globulos. También se incluye en el alcance de la presente cápsulas de gelatina rígida que contienen, además de laspequenas esferas o globulos de estavudina, pequenas esferas o globulos similares que contienen otros agentes terapéuticos utilizados para tratar infeccionesretrovira les.
