PURPOSE The present work describes the development and in vitro and in vivo evaluation of a mucoadhesive nanoparticulate docetaxel (DTX) formulation for intravesical bladder cancer therapy. EXPERIMENTAL DESIGN Mucoadhesive formulations based on hyperbranched polyglycerols (HPG), hydrophobically derivatized with C(8)/C(10) alkyl chains in the core and modified with methoxy-polyethylene glycol ...

Emerging antibiotic resistance in pathogens has posed considerable challenges to explore and examine the natural antimicrobials (NAMs). Due labile nature of NAMs, nano-delivery systems (NDS) are required protect them from physiological degradation allow controlled delivery targeted site infection. In this study, corona modified NDS were developed using bovine serum albumin (BSA) on a chitosan c...

Zolmitriptan (ZT) is a well-tolerated drug in migraine treatment suffering from low bioavailability due to low amount of the drug that reaches the brain after oral and nasal delivery. Development of new nasal mucoadhesive nanoemulsion formulation for zolmitriptan may success in delivering the drug directly from the nose to the brain to achieve rapid onset of action and high drug concentration i...

The present study was performed to design and evaluate the famotidine loaded mucoadhesive nanosuspension for aspirin induced ulcer. A 3-factor, 3-level Box-Behnken design was applied to study the effects of amount of the beads (X1), PVPK-30(X2) and Tween-80 (X3) on the particle size (Y1), and cumulative percentage drug released after 1h (Y2). The optimization was performed using the desirabilit...

Mucoadhesive drug therapy destined for localized drug treatment is gaining increasing importance in today's drug development. Chitosan, due to its known biodegradability, bioadhesiveness and excellent safety profile offers means to improve mucosal drug therapy. We have used chitosan as mucoadhesive polymer to develop liposomes able to ensure prolonged residence time at vaginal site. Two types o...

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...

Objectives: There are various obstacles in the eradication of Helicobacter.pylori (H. pylori) infections, including low antibiotic levels and poor accessibility of the drug at the site of the infection. This study describes the preparation and characterisation of novel floatingmucoadhesive alginate beads loaded with clarithromycin (CMN) for delivery to the gastric mucosa to improve the eradicat...

Objective(s): Drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. Liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. Coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. Our studies aim at preparation and characterization of trimethylchitosan-...

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. ...

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 aqueo...
