novel supercritical carbon dioxide impregnation technique

The formulation of BCS Class II drugs as amorphous solid dispersions has been shown to provide advantages with respect to improving the aqueous solubility of these compounds. Whilehot meltextrusion (HME) and spray drying (SD) are among the most common methods for the production of amorphous solid dispersions (ASDs), the high temperatures often required for HME can restrict theprocessing…

hot meltextrusion of heat sensitive and high melting

Using tadalafil (TD) as a representative of heat-sensitive drug with high melting point and strong crystallization tendency, we observed that recrystallization of the prepared amorphous materials during extrusion can result in failure of amorphous solid dispersion (ASD) extrusion. Such recrystallizationprocessof amorphous TD during reheatingprocesswas investigated systematically
