dissolution enhancement of glybenclamide by a supercritical fluid-based solvent -antisolvent technique

dissolution enhancement of glibenclamide by solid dispersion: solvent evaporation versus a supercritical fluid-based solvent -antisolvent technique

glibenclamide (glib) is a poorly soluble drug with formulation-dependent bioavailability. therefore, we attempted in this study to improve glib dissolution rate by preparing drug solid dispersions by solvent evaporation (se) and supercritical fluid solvent-antisolvent techniques (scf-sas). a d-optimal mixture design was used to investigate the effects of different ratios of hpmc e5 (50-100%), p...

Clay exfoliation and polymer/clay aerogels by supercritical carbon dioxide

Supercritical carbon dioxide (scCO2) treatments of a montmorillonite (MMT) intercalated with ammonium cations bearing two long hydrocarbon tails (organo-modified MMT, OMMT) led to OMMT exfoliation, with loss of the long-range order in the packing of the hydrocarbon tails and maintenance of the long-range order in the clay layers. The intercalated and the derived exfoliated OMMT have been deeply...

Supercritical water as a solvent.

Water is not restricted to moderate temperatures and low pressures, but can exist up to very high temperatures, far above its critical point at 647 K. In this supercritical regime, water can be gradually compressed from gas-like to liquid-like densities. The resulting dense supercritical states have extraordinary properties which can be tuned by temperature and pressure, and form the basis for ...
