ABSTRACT
The behavior of different technological variants of fast release tablets of Meprobamato (400 mg) obtained by wet granulation. The desintegration time and the percentage of the dissolved drug showed a significant dependence of the sodium lauryl sulfate /sodium croscarmelose ratios present in formulae. The physical and chemical properties of tablets were assessed during 6 months (accelerated stability and dring 24 months (useful life), respectively. From the formulae selected it was possible to obtain granulates and tablets with organoleptic, physicomechanical and technological properties, demonstrating the feasibility of the process of fabrication of this product. Results showed the good stability in the immediate release of Meprobamato tablets selected. The in vitro dissolution hasn't significant differences, thus, neither the time elapsed nor the composition of formula inluenced on the percentages of dissolved drug. The assessment demonstrated significant differences, however, assessed formulae fulfilled with official pharmaceutical specifications during 24 months
RESUMEN
Se estudió el comportamiento de diferentes variantes tecnológicas de tabletas de liberación inmediata de meprobamato (400 mg), obtenidas por granulación húmeda. El tiempo de desintegración y el porcentaje de fármaco disuelto mostraron dependencia significativa con las proporciones del lauril sulfato de sodio/croscarmelosa sódica en las formulaciones. Se evaluaron las propiedades físicas y químicas de las tabletas durante 6 meses (estabilidad acelerada) y 24 meses (de vida útil), respectivamente. Se obtuvieron a partir de las formulaciones seleccionadas granulados y tabletas con propiedades organolépticas, físico-mecánicas y tecnológicas satisfactorias, lo que indicó la factibilidad del proceso de fabricación de este producto. Los resultados demostraron la buena estabilidad de las formulaciones de tabletas de liberación inmediata de meprobamato seleccionadas. La disolución in vitro no mostró diferencias significativas, por lo que ni el tiempo transcurrido ni la composición de la formulación influyeron sobre los porcentajes del fármaco disuelto. La valoración mostró diferencias significativas, sin embargo, las formulaciones evaluadas cumplieron con las especificaciones farmacéuticas oficiales durante 24 meses
