The objective of the present work was extraction of polysaccharide from Senna tora L. seed and its characterization as a pharmaceutical excipient. Polysaccharide extraction was based on mechanical separation of the endosperm of seeds of Senna tora, water dissolution, centrifugation, and precipitation with acetone. Standard procedures were used to study the viscosity, micromeritic properties, an...

The tablets manufactured by direct compression method using co-processed excipient showed relatively better disintegration time and in vitro drug release, with omission of number of laborious steps as compared to tablets manufactured by conventional wet granulation method. Melt granulation technique is a potential alternative for the development of directly compressible adjuvants. Lactose and m...

The irritation effects of ibuprofen, a widely used non-steroidal anti-inflammatory drug (NSAID), were evaluated on mouse gastric and duodenal mucosa when suspended in 0.5% (w/v) sodiumcarboxymethylcellulose (NaCMC) solution and loaded in alginate beads. The ionotropic gelation method was used to prepare controlled release alginate beads of ibuprofen. The influence of various formulation factors...

PURPOSE The purpose of this work was to preparation of vancomycin (VCM) biodegradable nanoparticles to improve the intestinal permeability, using water-in-oil-in-water (W/O/W) multiple emulsion method. METHODS The vancomycin-loaded nanoparticles were created using double-emulsion solvent evaporation method. Using Eudragit RS100 as a coating material. The prepared nanoparticles were identifyed...

piroxicam, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. consequently, the aim of this study was to improve the dissolution of piroxicam. microparticles containing piroxicam were produced by spray drying, using isopropyl alcohol and water in the ratio of 40:60 v/v as solvent system, and spray chilling technology by melting the ...

objective(s) ibuprofen is a problematic drug in tableting, and dissolution due to its poor solubility, hydrophobicity, and tendency to stick to surface. because of the bad compaction behavior ibuprofen has to be granulated usually before tableting. however, it would be more satisfactory to obtain directly during the crystallization step crystalline particles that can be directly compressed and ...
