Objective(s):The aim of this study was to prepare electrospun nanofibers of celecoxib using combination of time-dependent polymers with pectin to achieve a colon-specific drug delivery system for celecoxib. Materials and Methods:Formulations were produced based on two multilevel 22 full factorial designs. The independent variables were the ratio of drug:time-dependent polymer (X1) and the amoun...

objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...

Colonic drug delivery has gained remarkable importance for the delivery of the drugs for the treatment of local diseases associated with the colon. To achieve successful colonic delivery, colon targeting is of prime importance. Various natural therapies, available for the treatment of colonic diseases like ulcerative colitis, Intestinal bowel syndrome, colon cancer, diverticulitis, etc., are ba...

BACKGROUND AND THE PURPOSE OF THE STUDY Pectin derivatives have been utilized for colonic drug delivery (CDD). In this study the effects of different formulation variables upon the characteristics of pectinate microparticles (MPs) prepared by ionotropic gelation technique for colonic delivery of mesalazine was investigated. METHODS In-vitro drug release of MPs was studied using USP XXIV disso...

In the current year colonic drug delivery has gained significance for delivery of drug for the treatment of local diseases related with colon and systemic delivery of therapeutic peptides and proteins. Management could be more effective if it is possible for drug to be directly delivered to colon. This article gives an overview on different approaches utilized for colon specific drug delivery.

Colonic targeting has gained increasing interest over the past years. A considerable number of patents and publications dealing with the colon specific drug delivery system indicate a growing focus of research activities in this field, not just for the delivery of the drugs for the treatment of the local pathologies associated with the colon but also for its potential for the systemic delivery ...

In our current study, a newer amine functionalized guar gum derivative was studied for its efficacy in colonic drug delivery. Glycyrrhizic acid mono-ammonium salt was used as the model drug. Drug-loaded microparticles were formulated by ionic crosslinking using sodium tripolyphosphate. The Scanning Electron Microscopic study revealed spherical particles of sizes from 4.9 ± 3.8 μm to 6.9 ± 3.9 μ...

BACKGROUND AND AIMS Recent studies have shown that low molecular weight heparins are effective in the treatment of inflammatory bowel disease. Therefore, there is considerable interest in the development of an oral colonic delivery pharmaceutical system allowing targeted release of heparin in the inflamed tissue. The objective of this study was to prepare microparticles for the oral administrat...
