Continuous twin-screw granulation for enhancing the dissolution of poorly water soluble drug

Continuous twin-screw granulation for enhancing the dissolution of poorly water soluble drug.

The article describes the application of a twin-screw granulation process to enhance the dissolution rate of the poorly water soluble drug, ibuprofen (IBU). A quality-by-design (QbD) approach was used to manufacture IBU loaded granules via hot-melt extrusion (HME) processing. For the purpose of the study, a design of experiment (DoE) was implemented to assess the effect of the formulation compo...

Improvement of dissolution property of poorly water-soluble drug by supercritical freeze granulation.

The dissolution property of the poorly water-soluble drug, flurbiprofen (FP) was improved by a novel supercritical freeze granulation using supercritical carbon dioxide. Supercritical freeze granulation was defined as a production method of the granulated substances by using the dry ice to generate intentionally for the rapid atomization of the supercritical carbon dioxide to the atmospheric pr...

Continuous Granulation with a Twin-Screw Extruder

Influence of Solid Drug Delivery System Formulation on Poorly Water-Soluble Drug Dissolution and Permeability.

The majority of drugs have a low dissolution rate, which is a limiting step for their absorption. In this manuscript, solid dispersions (SD), solid self-microemulsifying drug delivery systems (S-SMEDDS) and solid self-nanoemulsifying drug delivery systems (S-SNEDDS) were evaluated as potential formulation strategies to increase the dissolution rate of carbamazepine. Influence of increased disso...

Evaluation of Some Novel Techniques For Dissolution Enhancement of Poorly Water Soluble Drug Nimodipine

Nimodipine (NMP), a Ca channel blocker, has a low oral bioavailability due to poor solubility and insufficient dissolution rate. In order to improve the same, various techniques were employed viz., evaporative precipitation into aqueous solution (EPAS), spherical agglomeration (SA) and solid dispersion using solvent evaporation and meltmixing. Formulations so prepared were characterised by diff...
