Abstract As performance of ternary amorphous solid dispersions (ASDs) depends on the solid-state characteristics and polymer mixing, a comprehensive understanding of synergistic interactions between the polymers in regard of dissolution enhancement of poorly soluble drugs and subsequent…

Amorphous solid dispersions (ASDs) are an enabling formulation approach used to enhance bioavailability of poorly water-soluble molecules in oral drug products. Drug-rich amorphous nanoparticles generated in situ during ASD dissolution maintain supersaturation that drives enhanced absorption.…

Evolving therapeutic landscape through combinatorial chemistry and high throughput screening have resulted in an increased number of poorly soluble drugs. Drug delivery strategies quickly adapted to convert these drugs into successful therapies. Amorphous solid dispersion (ASD) technology is widely…

This work developed immediate-release hot melt extruded pellets containing the poorly aqueous soluble drug Indomethacin with five different screw configurations for oral application. Moreover, numerical simulation concerning residence time was performed for each configuration to give valuable tools…

Amorphous solid dispersions (ASDs) are commonly used to increase the dissolution rate of poorly soluble active pharmaceutical ingredients (APIs). Unfortunately, most ASDs are thermodynamically unstable and, even though kinetically stabilized, will thus eventually crystallize. The crystallization…

Nowadays, a high number of pipeline drugs are poorly soluble and require solubility enhancement by e.g., manufacturing of amorphous solid dispersion. Pharmaceutical 3D printing has great potential in producing amorphous solid oral dosage forms. However, 3D printing techniques differ greatly in terms…
