in this work, we report synthesis and characterization of bi2o3 nanoparticles loaded on mesoporous mcm-41 nanoparticles by a simple solid-state dispersion (ssd) method. monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous mcm-41 as a supporting material. fourier transform infrared spectroscopy (ft-ir), x-ray p...

KRN633 is a potent inhibitor of vascular endothelial growth factor (VEGF) receptor tyrosine kinases. However, it is poorly water-soluble; consequently, relatively high doses are required to achieve substantial in vivo tumor growth suppression after oral administration. We subjected KRN633 to the solid dispersion technique to improve its solubility, absorption, and antitumor efficacy after oral ...

Curcumin is coming from the Curcuma longa which gives golden color and have the biological importance. As per the survey it is water insoluble, the poor solubility and wettability of curcumin leads to poor dissolution and hence shows poor bioavailability. The present study is aimed at increasing solubility of drug using solid dispersion technique. The solid binary systems were prepared using di...

The objective of this work was to improve aqueous solubility of poorly water soluble drugs by a modified porous starch as solid dispersion carrier. The yield of the porous starch was found to be 80%. The flow property of the prepared porous starch was found to be good, with good compressibility index. The particle size of the prepared porous starch were found to be in the range of 53–130μ. Ther...

solid dispersions in water-soluble carriers have attracted considerable interest as a means of improving the dissolution rate, and hence possibly bioavailability, of a range of hydrophobic drugs. the poor solubility of carvedilol leads to poor dissolution and hence variation in bioavailability. the purpose of the present investigation was to increase the solubility and dissolution rate of carve...

meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. the aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (peg) 6000. the effect of solubilization by...

Surface solid dispersion with insoluble carriers is considered a recently developed technique, widely applied for the enhancement of solubility and dissolution of poorly water soluble drugs. The objective of this research article is to study the effect of surface solid dispersion of ketoprofen with colloidal silicon dioxide (Aerosil 200) on the dissolution rate. Surface solid dispersion (Adsorb...

The solubility behaviour of drug is one of the most challenging aspects in formulation development. Thus a greater understanding of dissolution and absorption behaviour of drug with low aqueous solubility is required to successfully formulate them into more soluble and hence bioavailable drug product. Therefore different approaches are being explored to enhance the solubility of poorly water so...
