Impact of polymer chemistry on critical quality attributes of selective laser sintering 3D printed…
The aim of this study is to investigate the influence of polymer chemistry on the properties of oral dosage forms produced using selective laser sintering (SLS). The dosage forms were printed using different grades of polyvinyl alcohol or copovidone in combination with indomethacin as the active…

Review of industrially recognized polymers and manufacturing processes for amorphous solid…
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…

Numerical simulation of five different screw configurations used during the preparation of hot-melt…
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…

Viscoelastic Behavior of Supercooled and Glassy ASDs at Humid Conditions Can Be Predicted
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…

3D printing of amorphous solid dispersions: A comparison of fused deposition modeling and…
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…

Selective laser sintering additive manufacturing of dosage forms: Effect of powder formulation and…
Large batches of placebo and drug-loaded solid dosage forms were successfully fabricated using selective laser sintering (SLS) 3D printing in this study. The tablet batches were prepared using either copovidone (N-vinyl-2-pyrrolidone and vinyl acetate, PVP/VA) or polyvinyl alcohol (PVA) and…

Downstream processing of amorphous solid dispersions into tablets
Amorphous solid dispersions have gained tremendous attention as a commercially viable solubility enhancement technique for poorly water-soluble drugs. However, poor drug loading associated with poor drug-polymer miscibility is a major challenge in the downstream processing of ASDs. While many…

Drop-on-powder 3D printing of amorphous high dose oral dosage forms: Process development,…
Drop-on-powder 3D printing is able to produce highly drug loaded solid oral dosage forms. However, this technique is mainly limited to well soluble drugs. The majority of pipeline compounds is poorly soluble, though, and requires solubility enhancement, e.g., via formation of amorphous solid…

Solubility Enhanced Formulation Approaches to Overcome Oral Delivery Obstacles of PROTACs
PROteolysis TArgeting Chimaeras (PROTACs) offer new opportunities in modern medicine by targeting proteins that are undruggable to classic inhibitors. However, due to their hydrophobic structure, PROTACs typically suffer from low solubility, and oral bioavailability remains challenging. At the same…
