Objective: the objective of the present work was extraction of polysaccharide from tamarind seed and further characterization as pharmaceutical excipient. study includes phytochemical screening, micromeritic properties. Work also emphasize to study gelling properties of extracted polysaccharide. Methods: Water based extraction procedure was used to extract polysaccharide from tamarind seed. Pha...

Spherically agglomerated solid dispersions of carvedilol (CAR) were prepared with polyvinyl-pyrrolidone (PVP) using acetone, water and dichloromethane as solvent, non-solvent and bridging liquid, respectively. The prepared agglomerates were evaluated for its percentage yield, drug content, morphology, thermal behavior, micromeritic properties, aqueous solubility and in vitro drug release. Diffe...

Floating drug delivery system is one of the novel drug delivery system. Floating drug delivery system have a bulk density less than gastric fluids and thus it remains buoyant in the stomach without affecting gastric emptying rate for a prolonged period of time. Verapamil HCL is calcium channel blocker drug with short elimination half-life 2.8-7.4 hours Floating microspheres of Verapamil HCL wer...

Objective: The main objective was to isolate and characterise a naturally obtain polysaccharides which have the property to formulate sustain release product. Methods: Tamarind Seed Polysaccharides (TSP) was isolated from seed of Tamarindus indica by crushed the seed into powder and boiled with water at 45 °C to extract the polysaccharides. After boiling for 12 h the supernatant liquids were co...

Background: Polyelectrolyte complexes are complexes formed by interaction of two oppositely charged ions. This study deals with formation of chitosan–Aegle marmelos polyelectrolyte complex. Polyelectrolyte complex was found to be used as pharmaceutical excipient. Aim: The present study aimed to synthesize Chitosan–Aegle marmelos polyelectrolyte complex and their characterization and to compare ...

Direct tableting has been renewed as a preferable process by simply mixing and compressing powder to save time and cost in comparison with granule tableting. Direct compression tableting as a technique has been successfully applied to numerous drugs on the industrial scale, although the success of any procedure, and resulting mechanical properties of tablets, is strongly affected by the quality...
