a etilcelulosa (EC) ha sido ampliamente usada como material adecuado en el desarrollo de nuevos sistemas para liberación modificada de fármacos. Algunos oligo-polisacáridos como inulina (IN), goma guar(GG) y sus deriv...

"En la industria autopartista mundial, la fundición por inyección es la técnica más utilizada para la conformación de componentes. Estos procesos presentan un gran número de ventajas en comparación a otros proceso...

Polymeric membranes have been used as wound dressings for burns and healing wounds. Healing properties, anti-inflammatory and antibiotic in such membranes can be induced and/or made possible with the incorporation of bio...

The purpose of this work was to design and evaluate a novel vaginal delivery system for the local treatment of vaginal candidiasis. Bioadhesive vaginal films of metronidazole that could be retained in the vagina for prol...

The aim of the present study was to develop a sustained release mucoadhesive buccal film of naproxen, which can be used to treat the inflammation in the oral cavity. The mucoadhesive buccal films were prepared by solve...

Free films were obtained by the combination of a polymer EudragitTM FS30D and oligosaccharides (alpha or gamma-CDs), by a casting process. The films were characterized by DSC, TGA, FTIR and SEM. The influence of composit...

Filmes isolados do sulfato de condroitina (SC) associado à Etilcelulose (EC) obtidos pelo processo de evaporação "casting process" em placa de Teflon®, foram investigados para determinação Ii % em fluidos de simula...

Nuestra tesis se dirige a convertir en protagonistas a una serie de personajes que por lo general han oficiado el papel de actores de reparto en las investigaciones sobre las obras estelares de la Historia del Pensamient...

El trabajo describe un sistema de dispositivo de liberacíon lenta de droga de una película de quitosano cargada de tetraciclina con efecto antibiótico sostenido. Las películas de quitosano (CF) que contenían tetraci...

Materiais poliméricos foram propostos no desenvolvimento de novos excipientes potencialmente biodegradáveis para liberação colo-específico de fármacos. Oligossacarídeo α-gluco-oligossacarídeo (α- GOS/Bioecolian...

Transdermal drug delivery systems of venlafaxine hydrochloride were prepared by using combination of hydrophilic (HPMC E15) and hydrophobic (ERS100 and ERL 100) polymers in 1:5, 2:4, 3:3, 4:2, 5:1 ratios by solvent casti...
