dc.description.abstract | En el presente estudio, se desarrollaron nuevas formulaciones de indometacina para mejorar la velocidad de disolución de la indometacina mediante la preparación de dispersiones sólidas mediante el método de liofilización. El grado de alteración de la cristalinidad de la indometacina se evaluó según el método de preparación y mediante la adición de hidroxipropilcelulosa poco sustituida. Las dispersiones sólidas mejoraron la velocidad de disolución de la indometacina. El uso combinado de microscopía electrónica de barrido, difracción de rayos X en polvo y calorimetría diferencial de barrido reveló la base del aumento en la velocidad de disolución de la indometacina cuando se formula como dispersiones sólidas de hidroxipropilcelulosa poco sustituidas. | |
dc.description.abstract | In the present study, new indomethacin formulations were developed in order to enhance the indomethacin dissolution rate by preparing solid dispersions using the freeze-drying method. The degree of alterations in the crystallinity of indomethacin was assessed according to the preparation method and by the addition of low-substituted hydroxypropyl cellulose. Solid dispersions improved the dissolution rate of indomethacin. Combined use of scanning electron microscopy, X-ray powder diffraction and differential scanning calorimetry revealed the basis of the increase in dissolution rate of indomethacin when formulated as lowsubstituted hydroxypropyl cellulose solid dispersions. | eng |
