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...

Pharmaceutical approaches based on nanotechnologies and the development of eye drops composed of the mucoadhesive polymers chitosan and hyaluronic acid are emerging strategies for the efficient treatment of ocular diseases. These innovative nanoparticulate systems aim to increase drugs' bioavailability at the ocular surface. For the successful development of these systems, the evaluation of muc...

The use of natural polymers in the drug delivery continues to be an area of intensive research despite the advent of several new synthetic polymers. The present study envisages pharmaceutical utility of Assam glutinous rice as natural biopolymeric matrix for microfabricated controlled DDS. Microcarriers were prepared using an industrially feasible ionic gelation method using the blends of propo...

The work investigates the development and optimization of ionotropically-gelled mucoadhesive beads composed of tamarind seed polysaccharide (TSP)-alginate polymer-blend for oral delivery of metformin HCl using 32 factorial design. The optimized mucoadhesive beads exhibited 94.86 ± 3.92 % drug encapsulation efficiency and good mucoadhesivity with the biological membrane in wash-off test, and sus...

Natural materials are preferred over synthetic counterparts because of their biodegradable and biocompatible nature. The present work was proposed to utilize mucilage from natural source for the development of controlled release formulation of metformin hydrochloride. Natural mucilaginous substance extracted from Dillenia indica L. (DI) fruit was used in fabricating controlled release microsphe...

The present work envisages utilisation of biodegradable and biocompatible material from natural sources for the development of controlled release microspheres of metformin hydrochloride (MetH). Natural polysaccharides extracted from Dillenia indica L. (DI), Abelmoschus esculentus L. (AE) and Bora rice flour were used in fabricating controlled release microspheres. The microspheres were prepared...

Inhalation Ciprofloxacin HCl microspheres were formulated with combination of alginate and kappa carrageenan a total 1% (F1), 1.5% (F2), 2% (F3). Aim this research is to examine effect polymer concentration on characteristics, release, lung deposition microspheres. Microspheres characterized including loading, efficiency, yield, size, moisture content, mucoadhesivity, release. Deposition was st...

Combining mucoadhesive characteristics of a biodegradable polymer such as chitosan with the potential to enhance drug release by increasing the solubility of poorly water-soluble drugs has great potential for pharmaceutical technology and drug delivery design. Polymeric delivery systems have been extensively researched in an attempt to achieve modified drug release. Cyclodextrins (CD) offer an ...
