Taschenbuch. Zustand: Neu. Neuware -Self-microemulsifying drug delivery system (SMEDDS) of Nitrendipine was aimed at overcoming the problems of poor solubility and bioavailability. The formulation strategy included selection of oil phase based on saturated solubility studies and surfactant and co-surfactant screening on the basis of their emulsification ability. Ternary phase diagrams were constructed to identify the self-emulsifying region. Ethyl oleate as oil, Cremophore RH40 as surfactant and PEG 400 as co-surfactant were concluded to be optimized components. The prepared SMEDDS was characterized through its droplet size, zeta potential, self micro emulsification time and drug content determination. The optimized formulation exhibited 98 % in vitro drug release, which was significantly higher than that of the drug solution. Infrared spectroscopy, differential scanning calorimetric, SEM and x-ray diffraction studies indicated no incompatibility between drug, oil and surfactants. From the stability studies of solid SMEDDS, there was no significant decrease in drug release and drug content, hence the formulation is found to be stable and then Comparative in vitro release study of optimised batch.Books on Demand GmbH, Überseering 33, 22297 Hamburg 52 pp. Englisch.

Mucoadhesion is a novel area of interest in the design of drug delivery systems to maintain the dosage form at the site of action or absorption and to facilitate intimate contact of the dosage form with underlying absorption surface to improve and enhance bioavailability. Repaglinide is a meglitinide analogue used as oral hypoglycaemic drug and having very low t1/2 (~ 1hr.), 56% bioavailability. It is totally absorbed from GIT, so it is the need to increase its transit time, by formulating with HPMC K4M, sodium alginate and Carbopol 934 P. Sodium alginate microspheres for an anti diabetic drug, repaglinide, were prepared by ionic-gelation method and investigated for its various physicochemical and release properties. Incorporation of HPMC K4M and Carbopol 934 P in the formulations affected the mucoadhesion, % water absorption, shape and release pattern of the formulations. Drug release from the microspheres followed peppas order kinetics. The prepared batches were found to sustained the release of the drug for 12 hours.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Englisch.

El comprimido mucoadhesivo preparado por el método de compresión directa se utilizó variando las concentraciones de HPMC K4M y alginato de sodio y (1:1, 1:1,5, 1:2) la proporción de fármaco y polímero.Las formulaciones se evaluaron y los resultados revelaron que los estudios FTIR no mostraron evidencia de interacciones entre el fármaco y los excipientes utilizados. La fuerza mucoadhesiva, el tiempo de residencia y el contenido de fármaco de la formulación F3 resultaron ser 26,35 ± 1,15 mg, >7,5 horas y 98,75 ± 0,05 % respectivamente. La formulación F3 mostró una liberación sostenida del fármaco, es decir, un 75,71% en 12 h. Los estudios de la cinética de liberación in vitro revelan que las formulaciones se ajustan bien a la cinética de orden cero y el mecanismo de liberación del fármaco es el transporte de supercaso II. El estudio concluyó que la formulación de los comprimidos mucoadhesivos a partir del estudio de liberación acumulada del fármaco revela que el aumento de la concentración de polímeros adhesivos hace que la liberación del fármaco sea más lenta.

Taschenbuch. Zustand: Neu. Neuware -El objetivo del sistema automicroemulsionable de administración de fármacos (SMEDDS) de nitrendipino era superar los problemas de solubilidad y biodisponibilidad deficientes. La estrategia de formulación incluía la selección de la fase oleosa a partir de estudios de solubilidad saturada y la selección de tensioactivos y cosurfactantes en función de su capacidad de emulsificación. Se construyeron diagramas de fases ternarias para identificar la región de autoemulsificación. Se concluyó que el oleato de etilo como aceite, el Cremophore RH40 como tensioactivo y el PEG 400 como co-tensioactivo eran componentes optimizados. La SMEDDS preparada se caracterizó por su tamaño de gota, potencial zeta, tiempo de auto-microemulsificación y determinación del contenido de fármaco. La formulación optimizada mostró una liberación in vitro del fármaco del 98%, significativamente superior a la de la solución del fármaco. Los estudios de espectroscopia infrarroja, calorimetría diferencial de barrido, SEM y difracción de rayos X indicaron que no había incompatibilidad entre el fármaco, el aceite y los tensioactivos. A partir de los estudios de estabilidad de los SMEDDS sólidos, no se observó una disminución significativa en la liberación del fármaco ni en el contenido de fármaco, por lo que se considera que la formulación es estable y, a continuación, se realiza un estudio comparativo de liberación in vitro del lote optimizado.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Spanisch.
