Acetónido de triamcinolona sin conservantes

Abstract

Objetivo: La purificación del preparado comercial de triamcinolona acetónido disponible es importante para evitar el efecto potencialmente tóxico del disolvente alcohol bencílico. Presentamos una nueva técnica de preparación de triamcinolona en polvo, a partir de su forma pura, sin disolventes y diluida con agua destilada estéril. Dada su escasa solubilidad en agua se describe cómo preparar y controlar dicha suspensión. Material y método: El acetónido de triamcinolona es preparado por el Servicio de Farmacia del Hospital, en condiciones de máxima esterilidad, bajo campana de flujo laminar. La suspensión de triamcinolona es envasada en un vial primario, capsulado y posteriormente esterilizado en autoclave a 121ºC. Del vial primario se obtienen dosis individualizadas de 4mg/0,1ml. Resultados: Se obtiene la dosis real administrada (3,77mg/0,1ml) mediante cuantificación de triamcinolona por cromatografía líquida de alta resolución (HPLC). La estabilidad física, química y microbiológica conservando el vial entre 2-8º se mantiene a los 6 meses. Conclusión: Se presenta un método de preparación de triamcinolona en estado puro, obteniendo una concentración muy próxima a la dosis óptima, evitando el uso de disolventes y con máxima garantía de esterilidad.
