Objectives: Carvedilol (CVD) is a nonselective β-adrenergic blocker that suffers from low absolute bioavailability (25-35%) due to first-pass metabolism. CVD-loaded buccal tablets were developed as a promising approach to overcome this limitation. Methods: The bilayers tablets were prepared by the direct compression technique. CVD-containing layer was based on one of four high molecular weight ...

Biomucoadhesive tablets are widely used to formulate topical antifungal drugs for treating acute oral candidiasis. The research focuses on the pharmaco-technological control of certain bio-mucoadhesive tablets containing miconazole nitrate, formulas developed and prepared by the authors based on the original formulas. The analyzed parameters were: macroscopic aspect, physical-chemical (pH) and ...

The delayed release and mucoadhesive properties of Cedrela gum and hydroxypropylmethylcellulose blend in diclofenac sodium tablet formulations were evaluated. Tablets were prepared by direct compression and the crushing strength and detachment force were found to increase from 74.49 ± 1.22 to 147.25 ± 2.57 N and 0.302 ± 0.36 to 1.141 ± 0.05 N from low to high level of polymers, respectively. Th...

Buccoadhesive tablets of Metclopramide Hydrochloride were fabricated with objective of avoiding extensive first pass metabolism and to prolong its duration of action with reduction in dosing frequency. The mucoadhesive polymers used in the formulations were Carbopol 934P, Chitosan, HPMC K4M and HPMC K15M. Tablets were prepared by direct compression method using polymer in different ratios. The ...

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...

BACKGROUND The dilution and rapid elimination of topically applied drugs due to the flushing action of saliva is a major difficulty in the effort to eradicate infections of oral cavity. Utilization a proper delivery system for incorporation of drugs has a major impact on drug delivery and such a system should be formulated for prolonged drug retention in oral cavity. OBJECTIVES The aim of the...

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 ...

This study describes the in vitro/ex vivo buccal release of chlorhexidine (CHX) from nine mucoadhesive aqueous gels, as well as their physicochemical and mucoadhesive properties: CHX was present at a constant 1% w/v concentration in the chemical form of digluconate salt. The mucoadhesive/gel forming materials were carboxymethyl- (CMC), hydroxypropylmethyl- (HPMC) and hydroxypropyl- (HPC) cellul...

The two major problems in the development of new drugs are low aqueous solubility and oral bioavailability. Although, drug delivery via route is most preferred for years but it also has some drawbacks. Various techniques improving have been developed, however success these depends on physical chemical properties under development. In recent years, mucoadhesive gained high popularity comparison ...
