Purposes: Propranolol HCl is a beta blocker commonly used worldwide; however, it shows a low bioavailability due to its extensive first-pass metabolism. To solve this problem, a novel drug delivery system such as buccoadhesive system might be helpful. The aim of the present investigation is to prepare the buccoadhesive tablet of propranolol HCl using different mucoadhesive polymers. Method: Buc...

Magnetic Soft Robots In article number 2201813, Venkatsubramanian Kalpathy Venkiteswaran and co-workers develop a biocompatible soft polymer film for coating the outer surface of robot which can be controlled using magnetic fields. The Chitosan-Glycerol endows with ability locomotion on confined 3D surfaces through formation hydrogen bonds mucus-covered biological surfaces.

OBJECTIVE Betahistine dihydrochloride (BH.2HCl), an anti-vertigo histamine analog used in the treatment of Ménière's disease, undergoes extensive first-pass metabolism and suffers from short biological half-life. The aim of the present work was to develop and estimate controlled release mucoadhesive buccal tablets of BH.2HCl with a unidirectional drug flow to overcome this encumbrance. METHOD...

In the present work, stress was given for improvised local action of the drug with the addition of mucoadhesive polymer in the formulation. Oral mucoadhesive semi solid gel was prepared for the treatment of oral sub mucous fibrosis, which provides effect for extended periods of time. Curcumin was taken as a model drug as it exhibits profound antitumeric & antimutogenic activity. The semisolid p...

The present investigation reports the isolation of mucilage from Manilkara zapota seeds as per AOAC guideline and evaluating it as mucoadhesive agent. Manilkara zapota (Linn.) P. Royen syn. a small tree belonging to family sapotaceae. Physiochemical characteristics of mucilage, such as swelling index, microbial count, viscosity, hydration capacity, flow property, and pH were studied. The mucila...

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...

The present work aimed at studying the interaction between insulin and SiNP surfaced with mucoadhesive polymers (chitosan, sodium alginate or polyethylene glycol) and the evaluation of their biocompatibility with HepG2 and Caco-2 cell lines, which mimic in vivo the target of insulin-loaded nanoparticles upon oral administration. Thus, a systematic physicochemical study of the surface-modified i...

Drug actions can be improved by new drug delivery system, such as mucoadhesive system. This system remains in close contact with the absorption tissue, the mucous membrane, releasing the drug at the action site leading to improvement in both local and systemic effects. There are many routes of mucoadhesive drug delivery system, oral route is the most ancient as well as preferred by patient bein...

Mucoadhesive polymer-coated pellets containing metformin hydrochloride were prepared by the powder-layering technique using a centrifugal fluidizing (CF)-granulator. Four high-viscosity polymers were applied to make the pellets: 1) hydroxymethylcellulose (HPMC), 2) sodium alginate (Na-Alg), 3) HPMC/Carbopol, and 4) sodium carboxylmethylcellulose (Na-CMC). The physical crushing test, mucoadhesiv...
