Mucoadhesive drug delivery systems interact with the mucus layer covering mucosal epithelial surface, and mucin molecules increase residence time of dosage form at site absorption. Over past few decades, has received a great deal attention. forms may be designed to enable prolonged retention application, providing controlled rate release for improved therapeutic activity. The mucoadhesive abili...

Biopolymers possess highly favorable properties for electrochemical biosensing such as their inherent biocompatibility, inexpensive nature, and strong interfacial adhesion. In this mini-review, we will focus on chitosan polydopamine, two of the most commonly used biopolymers, sensing applications. Chitosan is a polysaccharide that exhibits high chemical resistance, offers straightforward modifi...

Microspheres constitute an important part of novel drug delivery system by virtue of their small size and efficient carrier capacity. Due to their short residence time, bioadhesive characteristics can be coupled to microspheres to develop mucoadhesive microspheres. Bioadhesion can be defined as the state in which two materials, at least one of which is biological in nature, are held together fo...

Oral cavity and oropharyngeal cancers are considered the eighth most common cancer worldwide, with relatively poor prognosis (62% of patients surviving 5 years, after diagnosis). The aim of this study was to develop a proof-of-concept mucoadhesive lozenge/buccal tablet, as a potential platform for direct sustained delivery of therapeutic antimitotic nanomedicines. Our system would serve as an a...

AIM To develop mucoadhesive liposomes by anchoring the polymer chitosan-thioglycolic acid (chitosan-TGA) to the liposomal surface to target intestinal mucosal membranes. METHODS Liposomes consisting of phosphatidylcholine (POPC) and a maleimide-functionalized lipid were incubated with chitosan-TGA, leading to the formation of a thioether bond between free SH-groups of the polymer and maleimid...

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 ...

Intranasal administration is an ideal alternative to the parenteral route for systemic drug delivery. Various conventional dosage forms have been employed for this purpose but they lack to provide the desired bioavailability of the drug due to poor residence time and faster clearance in the nasal cavity. Formulating multiparticulate system with mucoadhesive polymers may provide a significant in...

retardant. The gastric residence of conventional dosage form is typically short which transit rapidly through the small intestine in not more than 3h, thus rapid gastrointestinal (GI) transit phenomenon may consequently lead to reduction in the extent of absorption of various drugs. The present study was to develop mucoadhesive microsphere of aceclofenac and evaluate the effect of polymer conce...

Nanoparticles have proven to be an effective delivery system with few side effects for anticancer drugs. In this study, gemcitabine-loaded nanoparticles have been prepared by an ionic gelation method using chitosan and Pluronic(®) F-127 as a carrier. Prepared nanoparticles were characterized using dynamic light scattering, Fourier transform infrared spectroscopy (FT-IR), differential scanning c...
