ABSTRACT
Objective Two carvedilol aqueous solutions and one carvedilol aqueous suspension for paediatric oral use (1mg/ml) were studied to determine their stability. Method All samples were stored at 4, 25 and 40°C. Carvedilol content of each of the three formulations was tested using high performance liquid chromatography (HPLC). Each sample was analysed in triplicate at 0, 3, 7, 14, 28 and 56 days. Results Carvedilol stayed stable in the acidic aqueous solution at the three different temperatures during the 56 days of the study. In the alkaline solution, carvedilol was stable during 56 days at 25°C, but only 28 days at 4 and 40°C. In the aqueous suspension, carvedilol was stable during 56 days at 4 and 25°C, but only 28 days at 40°C.ConclusionsAll the formulations that were tested can be stored at 25°C for at least 56 days(AU)
RESUMEN
Objetivo Se estudió la estabilidad de carvedilol (1mg/ml) en 2 soluciones acuosas y una suspensión acuosa para uso pediátrico. Método Las formulaciones fueron almacenadas a 4, 25 y 40°C. El contenido de carvedilol de cada una de las 3 formulaciones fue analizado por cromatografía líquida de alta eficacia (HPLC). Cada muestra fue analizada por triplicado a tiempos 0, 3, 7, 14, 28 y 56 días. Resultados Carvedilol se mantuvo estable en la solución acuosa de pH ácido durante los 56 días del ensayo a las 3 temperaturas estudiadas. En la solución alcalina fue estable 56 días a 25°C, pero sólo 28 días a 4 y 40°C. En la suspensión acuosa carvedilol fue estable 56 días a 4 y 25°C, y sólo 28 días a 40°C.ConclusionesTodas las formulaciones ensayadas pueden ser conservadas a 25°C al menos por un período de 56 días (AU)
