the objective of the present investigation was to design a sustained release floating microcapsules of theophylline using two polymers of different permeability characteristics; eudragit rl 100 (eu rl) and cellulose acetate butyrate (cab) using the oil-in-oil emulsion solvent evaporation method. polymers were used separately and in combination to prepare different microcapsules. the effect of d...

Cefdinir (Cef) is a third-generation cephalosporin antibacterial agent with an extended spectrum and low solubility permeability. In this study, cefdinir was prepared as nanosuspension lyophilized to powder. The further processed develop bilayer tablet. By utilizing the approach, first therapeutic action impacted by immediate part's rapid disintegration prolonged release from floating part achi...

Floating multi-layer coated tablets were designed based on gas formation. The system consists of a drug-containing core tablet coated with a protective layer (hydroxypropyl methylcellulose), a gas forming layer (sodium bicarbonate) and a gas-entrapped membrane, respectively. The mechanical properties of acrylic polymers (Eudragit RL 30D, RS 30D, NE 30D) and ethylcellulose were characterized by ...

The present study was carried out with an objective of preparation and in vitro evaluation of floating tablets of hydroxypropyl methyl cellulose (HPMC) and polyethylene oxide (PEO) using ranitidine hydrochloride as a model drug. The floating tablets were based on effervescent approach using sodium bicarbonate a gas generating agent. The tablets were prepared by dry granulation method. The effec...

The aim of the present study was to prepare floating matrix tablet glipizide by applying Simplex lattice design using kappa carrageenan, Hydroxypropylmethylcellulose K15M and sodium bicarbonate as independent variable. similarity factor (f2), time release 50 % drug 90 were taken dependent factors. A total 14 batches prepared given Design-Expert® Software (version- 9.0.6, Stat-Ease) response obt...
