The aim of this study was to investigate the rheological behavior and mucoadhesive nature of saliva substitutes, by incorporating various mucoadhesive polymers into an artificial saliva pump spray formulation. For this purpose various mucoadhesive polymers including cellulosic polymers in the range of 0.1-1.0% and Carbomers such as C974p, C971, C934p and C971 in the range of 0.01-0.1% were adde...

buccoadhesive drug delivery systems have distinct advantages in comparison with oral administration. plant exudates like gum or mucilage are being studied for their use as pharmaceutical adjuvant. the aim of this study is to evaluate the properties of the plantago major seed mucilage as a mucoadhesive agent and propranolol hydrochloride is chosen as a model drug. mucoadhesive tablets of propran...

The purpose of research work was to develop and optimize mucoadhesive microspheres of glibenclamide incorporated in in-situ gel for nasal delivery with the aim to enhance the residence time and improve therapeutic efficacy. Chitosan (mucoadhesive) based microspheres of glibenclamide were prepared by emulsificationcrosslinking method. Glutaraldehyde was used as crosslinking agent. A 32 factorial...

Among novel drug delivery systems, Buccal mucoadhesive systems have attracted great attention in recent years due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. Mucoadhesion may be defined as the process where polymers attach to biological substrate or a synthetic or natural macromolecule, to mucus or an epithelial surface. Buccal mucoadhes...

Thiol functionalization of psyllium was carried out to enhance its mucoadhesive potential. Thiolation of psyllium was achieved by esterification with thioglycolic acid. Thiolation was observed to change the surface morphology of psyllium from fibrous to granular and result in a slight increase in the crystallinity and swelling. Thiolated psyllium was found to contain 3.282 m moles of thiol grou...

Drug-Loaded Mucoadhesive Patch In article number 2100203, Sukho Park and co-workers demostrate a drug-loaded patch equipped in wireless capsule, which is delivered to the gastrointestinal tract rapidly accurately by an external magnetic field. The has excellent mucoadhesive properties even wet environment. Since nanoparticles doxorubicin are also loaded patch, it generates heat under alternatin...

A multilayered hydrogel film system based on hyaluronic acid-cysteamine (HA-Cym) and polyvinylalcohol (PVA) was fabricated. It contained a drug-impermeable backing layer, a supporting layer preventing direct contact between the loaded drug and the backing layer, a drug-loading layer and a mucoadhesive layer. Scanning electron microscopy demonstrated the presence of the distinct layers. The comp...
