Mucoadhesive drug delivery systems interact with the mucus layer covering the mucosal epithelial surface, and mucin molecules and increase the residence time of the dosage form at the site of absorption. The drugs which have local action or those which have maximum absorption in gastrointestinal tract (GIT) require increased duration of stay in GIT. Thus, mucoadhesive dosage forms are advantage...

The objective of this study was formulation and evaluation of mucoadhesive nanoparticles of acyclovir. Nanoparticles were prepared by one step desolvation method by using gelatin as a mucoadhesive polymer. The effects of amount of gelatin and Pluronic F-68 on particle size, polydispersity index, entrapment efficiency, loading efficiency, mucoadhesive strength were studied. Nanoparticulate formu...

A novel mucoadhesive buccal tablet containing flurbiprofen (FLB) and lidocaine HCl (LID) was prepared to relieve dental pain. Tablet formulations (F1-F9) were prepared using variable quantities of mucoadhesive agents, hydroxypropyl methyl cellulose (HPMC) and sodium alginate (SA). The formulations were evaluated for their physicochemical properties, mucoadhesive strength and mucoadhesion time, ...

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...

Mucoadhesive delivery systems offer several advantages over other oral controlled release systems by virtue of prolongation of residence time of drug, its targeting, and localization of the dosage form at a specific site. These advantages include bypass of first pass metabolism of the drug and hence more concentration of the drug is available for absorption. Mucoadhesion occurs between two surf...

the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...

The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. Propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934P as mucoadhesive polymer and ethyl cellulose as carrier ...

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...

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...

The aim of the present study was to prepare mucoadhesive multiparticulate system for oral drug delivery using ionic gelation technique. Microspheres of different mucoadhesive polymers including hydroxypropyl methylcellulose (HPMC) K15M and carbopol 971P were prepared. In this technique cross linking of sodium alginate with calcium chloride was done which retarded the release of drug from the mu...
