          Abstract

          Se validó un método de cromatografía líquida de alta resolución para el estudio de estabilidad del jarabe de loratadina 0,1 %. La curva de calibración en el rango de 13,6 a 3,36 µg/mL fue lineal, con un coeficiente de correlación igual a 0,99975; la prueba estadística para el intercepto y la pendiente, no significativa. El recobrado obtenido resultó de 100,2 % en el rango de concentración estudiado, y las pruebas de Cochran y Student (t), no significativas. El coeficiente de variación en el estudio de repetibilidad fue igual a 0,41 % para 10 réplicas ensayadas, mientras que en la reproducibilidad las pruebas de Fischer y Student, no significativas. El método resultó específico, lineal, preciso y exacto.

          A high resolution liquid chromatography method was validated to study the stability of loratidine syrup 0.1 %. The calibration curve in the range from 13.6 to 3.36 µg/mL was lineal, with a coefficient of correlation equal to 0.99975. The intercept and slope statistical test was not significant. The recovery obtained was 100.2 % in the concentration range studied, and the Cochran and Student (t) tests results were not important. The variation coefficient in the repeatability study was equal to 0.41 % for 10 replications assayed, whereas in the reproducibility Fischer and Student tests were not remarkable. The method proved to be specific, lineal, accurate, and exact.
