%X Los 車vulos de quitina constituyen nuevos productos en fase de investigaci車n. Para la evaluaci車n anal赤tica de estos, se desarroll車 un m谷todo gravim谷trico directo para supositorios vaginales de diferente dosificaci車n. La t谷cnica se basa en la separaci車n de la quitina de los dem芍s componentes de la formulaci車n seg迆n sus diferencias de solubilidad, con el empleo de la filtraci車n al vac赤o. El m谷todo se valid車 para control de calidad, y se obtuvieron resultados satisfactorios en los par芍metros evaluados: linealidad, precisi車n, exactitud y selectividad. Chitin pessaries are new products under research. For their analytical evaluation, a direct gravimetric method for vaginal suppositories of various dosing was designed. This technique was based on separation of chitin from the rest of the formulation components according to their solubility characteristics, by using vacuum filtering. The method was validated for quality control and the results were satisfactory in terms of the evaluated parameters such as linearity, precision, accuracy and selectivity.
