Abstract

Purpose: The objective of the study is to provide toxicological information through the HET-CAM test of Fluconazole and Voriconazole eye drops prepared commonly in Pharmacy Services for the treatment of fungal keratitis.

Method: Experimental Study. The ocular toxicity of topical voriconazole 10 mg/ml and fluconazole 2 mg/ml were evaluated by the hen's egg test (HET) on the chorioallantoic membrane (CAM). The effects on blood vessels were based on its behavior during 300 seconds and processes that may occur at each time, then we calculated the irritation index (is, irritation score).

Results and conclusions: Both eye drops, voriconazol and fluconazole have been proven to be safe, since the IS that we obtained was zero for both samples and did not present significant signs of irritation. Therefore, these eyedrops are considered suitable for ocular use from a toxicological point of view.

Objetivo: El objetivo del estudio es aportar información toxicológica mediante el ensayo HET-CAM, de los colirios de Fluconazol y Voriconazol elaborados de manera habitual en los Servicios de Farmacia para el tratamiento de las queratitis fúngicas. MÉTODOS: Estudio experimental en el que se ensaya la potencial toxicidad ocular del colirio de voriconazol 10 mg/ml y fluconazol 2 mg/ml mediante el método Hen s Egg Test-Chorioallantoic Membrane (HET-CAM). Los resultados se fundamentan en la observación de los posibles procesos dañinos que pudiesen ocurrir en los vasos sanguíneos de la membrana corioalantoidea del embrión de pollo durante un tiempo de contacto de 300 segundos, calculándose posteriormente el índice de irritación (IS, Irritation Score).

Resultados y conclusiones: Se obtienen IS nulos para ambas muestras, no mostrando por tanto indicios de irritación aguda apreciables, considerándose por tanto aptos para su utilización desde el punto de vista toxicológico.
