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...

This study describes the effect of Guar gum and chitosan on formulation of mucoadhesive drug delivery system of itraconazole. Mucoadhesive strength, Drug content, Hardness, Friability, Weight variation, Moisture content and accelerated stability studies were performed to study the effect of polymers on prepared mucoadhesive tablets. Results of the present study clarified the potential of guar g...

Amlodipine besylate microspheres for intranasal administration were prepared with an aim to avoid first-pass metabolism, to achieve controlled blood level profiles and to improve therapeutic efficacy. Hydroxypropyl Guar, a biodegradable polymer, was used in the preparation of microspheres by employing water in oil emulsification solvent evaporation technique. The formulation variables were drug...

Objective: The objective of the present work was to optimize a rectal suppository containing mucoadhesive pellets Mesalamine achieve local yet sustained release for once-a-day administration therapy Inflammatory Bowel Disease. Methods: Thus, involves forming mesalamine by extrusion spheronization, which were then loaded into be administered rectally. evaluated mucoadhesion strength, swelling po...

The objective of the current investigation is to reduce dosing frequency and improve patient compliance by designing and systematically evaluating sustained release microspheres enriched gel of econazole nitrate. An antifungal agent, Econazole nitrate, is delivered through the microparticulate system using ethyl cellulose as the controlled release polymer. Microspheres were developed by the emu...

Systemic administration of anticancer drugs is associated with a number of side effects. Therefore, it needs some targeted drug delivery system to deliver the drug which would ensure relief from side effects along with the direct delivery of drug to the site of action in a controlled manner. Keeping in view the importance of mucoadhesive polymers in site specific drug delivery, in the present w...

Pharmaceutical scientists around the globe have been seeking to discover as an alternative injections over last few, transdermal and transmucosal routes decades. The buccal cavity mucosa most convenient easily available site for distribution of local systemic therapeutic agents was found be dosage forms among numerous sitesavailable.Theories various polymers used in mucoadhesive drug delivery. ...
