Introducción: El trabajo de investigación se llevó a cabo para desarrollar una suspensión estable y eficaz de estiripentol para el tratamiento de la epilepsia.
Método: Se utilizó el estudio FT-IR para evaluar la compatibilidad entre el fármaco y el excipiente y también se examinó la apariencia física de la mezcla del fármaco y el excipiente después de un mes de estudio de estabilidad. La suspensión se preparó mediante un agitador mecánico y se evaluó la viscosidad, el pH, el volumen de sedimentación, el potencial zeta y los estudios de liberación de fármaco in vitro. La formulación optimizada se evaluó adicionalmente para determinar el potencial zeta y el índice de polidispersidad.
Resultados: Los resultados de FT-IR confirmaron la compatibilidad del fármaco y los excipientes. La apariencia física de la mezcla no se alteró durante las condiciones de almacenamiento aceleradas. La viscosidad, el pH y el volumen de sedimentación de la formulación oscilaron entre 22,92 ±1,2 cPs y 54,8 ± 2,1 cPs; 5,32 ± 0,04 y 6,01 ± 0,1 y 83,19 ± 0,9 % y 98,87 ± 1,2 % respectivamente. El potencial zeta y el índice de polidispersidad de la formulación optimizada fueron -52,1 mV y 0,198 respectivamente. Estos resultados fueron indicativos de una suspensión monodispersa estable. La formulación optimizada fue estable a temperaturas y humedad más altas y en presencia de luz, lo que indica una buena vida útil.
Conclusiones: El estudio demostró que la suspensión oral de estiripentol puede formularse como una forma farmacéutica estable y eficaz para el tratamiento de la epilepsia.
