Enhancement of dissolution profile for oral delivery of Fexofenadine Hydrochloride by solid dispersion (solvent evaporation) technique

Enhancement of dissolution profile for oral delivery of Fexofenadine Hydrochloride by solid dispersion (solvent evaporation) technique

The objective of present work is to investigate the enhancement of dissolution profile for oral delivery of Fexofenadine Hydrochloride (FH) through solid dispersion (SD) technique by the method of solvent evaporation. The SD was prepared by using ethanol as a solvent. Tablets were formulated containing solid dispersion of FH and compared with tablets of same formula without solid dispersion of ...

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...

Enhancement of Dissolution Rate of Efavirenz by Solid Dispersion Technique

Efavirenz is an HIV-1 specific, non-nucleoside reverse transcriptase inhibitor (NNRTI).It is an antiretroviral agent indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection, which is not soluble in water and lower absorption in gastric fluid. In order to improve the solubility and oral absorption of the drug in gastric fluid and to enhance its dissolution rate, soli...
