An oral suspension could a suitable dosage form for the geriatric patients. The calcium alginate coated ion exchange resinate of propranolol hydrochloride were prepared using Amberlite IR-120 by solvent evaporation. Microcapsules of propranolol hydrochloride resinate were prepared by solvent evaporation technique,the suspensions were prepared by using deionised water as the vehicle. Methy...

a great challenge in using natural polysaccharide as drug delivery system is their fast drug release. the purpose of the present study was to prepare and evaluate chitosan oligosaccharide (cho)-de-estrifiedtragacanth (det) core-shell nanoparticles for controled release of water soluble drugs. cho-det nanoparticles were prepared by microemulsion method and characterized by ft-ir spectroscopy. si...

Frequent dosing of the potent anti-androgen, flutamide, is necessary to reach a therapeutic level for the treatment of prostatic carcinoma. Sustained delivery of the drug could reduce the adverse effects such as gastrointestinal disorders and improve patient compliance. In the present study sustained-release matrix tablets of flutamide were prepared by direct compression method using different ...

Preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of Nile red-loaded solid lipid nanoparticles. Nanoparticles (NPs) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. To solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

In this study, the synthesis, characterization and controlled release behavior of new Hollow Silica Nano particles (HSNPs) and Magnetic Silica Nano Particles (MSNPs) were studied. Magnetic Silica Nano particles (MSNPs), as drug delivery vehicles, were synthesized through the coating of Fe3O4 nano-crystals with silica layers. The HSNPs were obtained by removal of Fe3O4 templates with hydrochlori...

Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...
