Considerable research efforts have been used in the development of floating drug delivery system including gas generation system, swelling systems and low density systems. In the development of low density systems the porous carriers are used because of its characteristics such as stable uniform porous structure, high surface area, tunable pore size and well-defined surface properties. This rev...
Gellan based floating beads of acetohydroxamic acid (AHA) were prepared by the ionotropic gellation method to achieve controlled and sustained drug release for treatment of Helicobacter pylori infection. The prepared beads were evaluated for diameter, surface morphology and encapsulation efficiency. Formulation parameters like concentrations of gellan, chitosan, calcium carbonate and the drug i...
The present investigation is concerned about the development of floating bioadhesive drug delivery system of venlafaxine hydrochloride which after oral administration exhibits a unique combination of floating and bioadhesion to prolong gastric residence time and increase drug bioavailability within the stomach. The floating bioadhesive tablets were prepared by the wet granulation method using d...
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...
