Intragastric buoyant tablets, i.e., gastro retentive drug delivery systems of Amoxycillin trihydrate were prepared with the objective to obtain site-specific drug delivery for the stomach and to extend its duration of action. The sustained release of amoxicillin is desired because of its short biological half-life. Part icularly to treat Helicobacter pylori infections, the sustained release is ...

Objective: The present study investigates the use of indomethacin–solubilizers solid dispersions for the development of controlled-release bilayer floating tablet formulations. Materials and Methods: The physical state of the dispersed indomethacin in the solubilizers mixture was characterized by Scanning electron microscopy, differential scanning calorimetry, powder X-ray diffraction, and IR s...

In the current study, floating dosage form containing acyclovir was developed to increase its oral bioavailability. Effervescent floating tablets containing 200 mg acyclovir were prepared by direct compression method with three different rate controlling polymers including Hydroxypropyl methylcellulose K4M, Carbapol 934, and Polyvinylpyrrolidone. Optimized formulation showed good floating prope...

Metformin hydrochloride (metformin HCl) was formulated as a hydrophobic matrix sustained release tablet employing wax materials and the sustained release behavior of the fabricated tablet was investigated. Sustained release matrix tablets containing 500 mg metformin HCl were developed using different bees wax combinations. The tablets were prepared by wet granulation technique. The formulation ...

The purpose of this research was to prepare floating calcium alginate beads of berberine for targeting the gastric mucosa and prolonging their gastric residence time. The floating beads were prepared by suspending octodecanol and berberine in sodium alginate (SA) solution. The suspension was then dripped into a solution of calcium chloride. The hydrophobic and low-density octodecanol enhanced t...

the purpose of this research was to prepare a floating matrix tablet containing domperidone as a model drug. polyethylene oxide (peo) and hydroxypropyl methylcellulose (hpmc) were evaluated for matrix-forming properties. a simplex lattice design was applied to systemically optimize the drug release profile. the amounts of peo wsr 303, hpmc k15m and sodium bicarbonate were selected as independen...

objective eudragits are widely used polymers in the production of oral sustained release dosage forms. the application of these polymers in the production of inert insoluble matrices has been investigated. however the effect of particle size, compaction force and presence of aerosil 200 as a glidant on the properties of eudragit rs and rl matrices prepared by direct compression of their physica...

Sustained release tablets of isoniazid were fabricated using guar gum and carbapol, Tragacanth Gum and PEG-6000, in different proportion and combinations by direct compression technique, Bulk density, tapped density, compressibility index, Hausner ratio before being punched as tablets. The tablets were evaluated for physical characteristic like hardness, weight variation, friability, and drug c...

The purpose of the present work was to design and optimize compression coated floating pulsatile drug delivery systems of bisoprolol. Floating pulsatile concept was applied to increase the gastric residence of the dosage form having lag phase followed by a burst release. The prepared system consisted of two parts: a core tablet containing the active ingredient and an erodible outer shell with g...

The purpose of the present work was to prepare buccal adhesive tablets of miconazole nitrate. The simplex centroid experimental design was used to arrive at optimum ratio of carbopol 934P, hydroxypropylmethylcellulose K4M and polyvinylpyrollidone, which will provide desired drug release and mucoadhesion. Swelling index, mucoadhesive strength and in vitro drug release of the prepared tablet was ...
