The goal of any drug delivery system is to provide a therapeutic amount of drug to the proper site in the body to achieve promptly & then maintain the desired drug concentration. That is why the drug delivery system should deliver dr ug at a state dictated by the needs of the body over a specified period of treatment. This idealized objective points to the two aspects most important to drug del...

The aim of this investigation was to design a novel Gas Empowered Drug Delivery (GEDD) system for CO(2) forced transport of peptide drugs together with mucoadhesive polymers to the surface of the small intestine. The GEDD effect of the core tablet was achieved using CO(2) gas to push insulin together with the mucoadhesive excipients poly(ethyleneoxide) (PEO) and the permeation enhancer trimethy...

For centuries, Spilanthes acmella (L.) Murr. (Fam. Compositae) has been recommended in traditional medicine for treatment of toothache, rheumatism and fever. Of the reported phytoconstituents of the plant, Spilanthol is known to possess antibacterial and anti inflammatory activity. The aim of the current investigation is to evaluate the potential of novel vesicular carrier, ethosomes, containin...

Purpose: To prepare and characterise ciprofloxacin mucoadhesive buccal films for localised, improved drug delivery in periodontitis. Methods: Ciprofloxacin-loaded buccal films containing 50 mg ciprofloxacin were prepared mucoadhesive polymers sodium cellulose (SCMC) and sodium alginate, using a solvent evaporation method. The films were evaluated in terms of thickness, weight, folding endurance...

UNLABELLED BACK GROUND AND THE PURPOSE OF STUDY: Sumatriptan succinate is a Serotonin 5- HT1 receptor agonist, used in treatment of migraine. It is absorbed rapidly but incompletely when given orally and undergoes first-pass metabolism, resulting in a low absolute bioavailability of about 15%. The aim of this work was to design mucoadhesive bilayered buccal tablets of sumatriptan succinate to ...

We developed novel acrylic-based polymers that can be used as mucoadhesive delivery systems. Poly(acrylic acid) hydrogels were modified by grafting adhesion promoter chains such as poly(ethylene glycol) (PEG) onto their back-bone chains, thus promoting the adhesive process by interpenetration. The copolymers synthesized were designated as P(AA-g-EG). Hydrogels were synthesized using PEG of two ...

The study was aimed to design and evaluate a new effervescent mucoadhesive vaginal drug delivery system for ciclopirox olamine (CPO), a broad-spectrum antifungal, antibacterial, and anti-inflammatory agent for effective treatment in vaginal candidiosis. Various polymers like Polyox 303, Carbopol 974P, HPMC K4M, Sodium CMC, HPC, Sodium Alginate, Xanthan Gum, Polycarbophil and Chitosan were used ...

In this paper, mucoadhesive in-situ gel with poloxamer and hydroxypropylmethylcellulose formulations of itraconazole were prepared for vaginal application. In addition, rheological, mechanical and mucoadhesive properties and syringeability of the formulations were characterized. The mixtures of Poloxamer 407 and 188 with two different types of hydroxypropylmethylcellulose were used as polymers ...

Mucoadhesive materials adhere persistently to mucosal surfaces. A mucoadhesive delivery system could therefore facilitate the controlled release of drugs and optimize their bioavailability in mucosal tissues. Polysaccharides are the most versatile class of natural polymers for transmucosal drug delivery. We used microviscosimetry to explore the mucoadhesion of a library of polysaccharide famili...

The objective of this study is to evaluate the effect of formulation variables on different evaluation properties such as cumulative percentage release and swelling index in development of two layered buccal mucoadhesive system consisting of a highly water soluble drug risedronate sodium. The mucoadhesive systems were developed with varied concentrations of the polymers (1-2%) using plasticizer...
