Solid Dispersion
Emulsion-electrospun polyvinyl alcohol nanofibers as a solid dispersion system to improve solubility…
We attempted to improve the solubility of poorly water-soluble drugs by preparing drug-loaded polyvinyl alcohol (PVA) nanofibers as a solid dispersion system via emulsion electrospinning. Probucol (PBC), a poorly water-soluble drug, was used as a model drug. Nanofibers were electrospun using an…

Exploration of theoretical and practical evaluation on Kollidon®SR matrix mediated amorphous…
The selection of an appropriate polymer for the preparation of amorphous solid dispersions via hot-melt extrusion (HME) deals with the study of various solid-state properties of drugs and polymers. Hence, before going to HME, it is necessary to have appropriate knowledge of drug-polymer miscibility,…

Efficient Development of Sorafenib Tablets with Improved Oral Bioavailability Enabled by…
An amorphous solid dispersion (ASD) of sorafenib (SOR) in hydroxypropyl methylcellulose acetate succinate (HPMC-AS), prepared by coprecipitation, was used to develop an immediate release tablet with improved oral bioavailability. An ASD of 40% drug loading with HPMC-AS (M grade), which exhibited…

Amorphous Solid Dispersions (ASDs): The Influence of Material Properties, Manufacturing Processes…
Poorly water-soluble drugs pose a significant challenge to developability due to poor oral absorption leading to poor bioavailability. Several approaches exist that improve the oral absorption of such compounds by enhancing the aqueous solubility and/or dissolution rate of the drug. These include…

Role of Permeability on the Biopredictive Dissolution of Amorphous Solid Dispersions
An ideal dissolution test for amorphous solid dispersions (ASDs) should reflect physicochemical, physiological, and hydrodynamic conditions which accurately represent in vivo dissolution. However, this is confounded by the evolution of different molecular and colloidal species during dissolution,…
