Floating hot-melt extruded tablets for gastroretentive controlled drug release system.
The purpose of this study was to investigate the influence of sodium bicarbonate on the physicochemical properties of controlled release hot-melt extruded (HME) tablets containing Eudragit RS PO and/or Eudragit E PO. Acetohydroxamic acid and chlorpheniramine maleate were used as model drugs. Sodium bicarbonate was incorporated into the tablet formulations and the drug release properties and buo...
متن کاملFloating Drug Delivery of Nevirapine as a Gastroretentive System
A multiple-unit floating drug delivery system based on gas formation technique was developed, in order to prolong the gastric residence time and to increase the overall bioavailability of the dosage form. The floating bead formulations were prepared by dispersing nevirapine together with calcium carbonate in a mixture of sodium alginate and hydroxypropyl methylcellulose solution and then drippi...
متن کاملHollow microspheres for gastroretentive floating- pulsatile drug delivery: preparation and in vitro evaluation.
PURPOSE A multiparticular floating-pulsatile drug delivery system was developed for time and site specific drug release of piroxicam. A blend of floating and pulsatile principles of drug delivery system would have the advantage that a drug can be released in the upper GI tract after a definite time period. METHODS Hollow microspheres were prepared by the emulsion solvent diffusion method usin...
متن کاملHot Melt Extrusion Technique
Various approaches have been adopted to address this including preparation of solid dispersions and solid solutions. Hot-melt extrusion is an efficient technology for producing solid molecular dispersions with considerable advantages over solvent-based processes such as spray drying and co-precipitation. Hot-melt extrusion has been demonstrated to provide sustained, modified, and targeted drug ...
متن کاملA Novel Approch : Pulsatile Drug Delivery System
Pulsatile drug delivery system (PDDS) is useful in the treatment of disease, in which drug availability is timed to match rhythms of disease, in order to optimize therapeutic effect and minimize side effects. PDDS have attracted attraction because of their multiple benefits over conventional dosage forms. The specific time that patients take their medication is very important as it has signific...
