drug delivery via buccal mucosa by means of buccoadhesive formulations offer distinct advantages over peroral administration. recently, plant gums and exudates have been screened for their use as pharmaceutical adjuvants. the aim of this study is to evaluate matrix tablets containing plantago psyllium seed mucilage in addition to carbopol as a mucoadhesive agent, and propranolol hydrochloride a...

conclusions algino-pectinate mucoadhesive formulations exhibited promising properties of a sustained release form for piroxicam and provided distinct tissue protection in stomach. objective the purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. materials and methods ionotropic gelation was us...

The purpose of research work was to develop and optimize mucoadhesive microspheres of glibenclamide incorporated in in-situ gel for nasal delivery with the aim to enhance the residence time and improve therapeutic efficacy. Chitosan (mucoadhesive) based microspheres of glibenclamide were prepared by emulsificationcrosslinking method. Glutaraldehyde was used as crosslinking agent. A 32 factorial...

OBJECTIVE S Mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease. MATERIALS AND METHODS Every discs containing 70 mg stem bark extract of Ziziphus jujuba were formulated by using Carbopol 934, PVP k30 and gelatin as polymers. Discs were made by granulation and direct compression. Discs were standardized based on the total phenol. Properties such as in vitr...

The aim of this study was to improve the mucoadhesive potential of xyloglucan polymer by the covalent attachment of cysteine as thiol moiety. The parent polymer xyloglucan was chemically modified by introducing sulphydryl bearing compound L-cysteine HCl. Different batches of xyloglucan-cysteine conjugates were prepared at varying reaction pH (2-6) and evaluated for optimum thiol incorporation, ...

The buccal region of oral cavity is an attractive site for administration of drug of choice. Buccal route is an excellent for systemic delivery of drug providing great bioavailability. A significant reduction in dose and dosing frequency can be achieved, thereby reducing dose dependent side effects, patient compliance and prolonging duration of action.Buccal dosage form increase bioavailability...

BACKGROUND Targeted drug delivery to colon would ensure direct treatment at the disease site, decrease in dose administration and reduction side effects improved drug utilization. OBJECTIVE The purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. MATERIALS AND METHODS Ionotropic gelation wa...

The nasal mucosa provides a potentially good route for local and systemic drug delivery. However, the protective feature of the nasal cavity make intranasal delivery challenging. The application of mucoadhesive polymers in nasal drug delivery systems enhances the retention of the dosage form in the nasal cavity. Several groups have investigated using low acyl gellan as a drug delivery vehicle b...

A self-folding miniature device has been developed to provide enhanced mucoadhesion, drug protection, and targeted unidirectional delivery. The main part of the device is a finger like bilayered structure composed of two bonded layers. One is a pH-sensitive hydrogel based on crosslinked poly(methyacrylic acid) (PMAA) that swells significantly when in contact with body fluids, while the other is...

Abstract: Aim and Objectives: The main motto of this work was to search the additive effect Datura stramonium leaves mucilage in making buccoadhesive film by taking Aceclofenac as a model drug. Materials Methods: Nine formulations buccal films were made using Carbopol 934 P varying proportions Ethyl Cellulose D. mucilage. judged for compatibility studies physical constraints including content d...
