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. ...

Drug delivery across mucus membranes is a particularly effective route of administration due to the large surface area. However, the unique environment present at the mucosa necessitates altered drug formulations designed to (1) deliver sensitive biologic molecules, (2) promote intimate contact between the mucosa and the drug, and (3) prolong the drug's local residence time. Thus, the pharmaceu...

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 study was to prepare and characterize mucoadhesive buccal tablets of glipizide using different Mucoadhesive polymers such as Carbopol 940, Sodium alginate and HPMC K15M in combination. Twenty one formulation were developed with different concentration of mucoadhesive polymers in each formulation.The formulated buccal tablets were tested for surface pH,in vitro drug release and moistu...

Mucoadhesive polymers have recently gained interest among pharmaceutical scientists as a means of improving drug delivery by promoting dosage form residence time and contact time with the mucous membranes. Mucoadhesion occurs between two surfaces, one of which is a mucous membrane and another is drug delivery system. Pharmaceutical aspects of mucoadhesion have been the subject of great interest...

OBJECTIVE Development of liposomal mucoadhesive drug delivery system, which is able to improve the bioavailability of poorly absorbed oral drugs by prolonging their gastric and intestinal residence time, through facilitating the intimate contact of the delivery system with the absorption membrane. MATERIALS AND METHODS Liposomes containing model drug atenolol were prepared by the modified eth...

   The objective of the present investigation was to develop and evaluate a contraceptive vagino-adhesive propranolol hydrochloride gel. To achieve this, various mucoadhesive polymers including guar gum (1-4% w/w), sodium alginate (4-7% w/w), xanthan gum (2-5% w/w ), HPMC 4000 (3-5% w/w), Na CMC (4-7% w/w), carbomer 934 and carbomer 940 both in the range of 0.5-2.0% w/w, were dispersed in an aq...

Nanoscale analysis may be used to design new types of mucoadhesive polymers. Understanding of the surface interactions between hydrophilic polymer surfaces and mucins can lead to improved adhesive bonding by hydrogen bonding. Alternatively, decoration of a mucoadhesive polymer surface with tethers of linear and block copolymers containing neutral or ionizable structures provides increased inter...

BACKGROUND AND OBJECTIVES Rheological evaluation of thermoreversible mucoadhesive nasal gel of zolmitriptan is done to determine the steady shear behaviour and gelation temperature. The thermoreversible mucoadhesive polymers are sucessesfully used to increase the contact time of the therapeutic compound in the nasal cavity as well as they cause enhancement in permeation of drug through the nasa...
