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 purpose of this study was to obtain an amorphous system with minimum unit operations that will prevent recrystallization of amorphous drugs since preparation, during processing (compression) and further storage. Amorphous celecoxib, solid dispersion (SD) of celecoxib with polyvinyl pyrrollidone (PVP) and co-precipitate with PVP and carrageenan (CAR) in different ratios were prepared by the ...
