Hydrophobic and hydrophilic thermoplastic poly(urethane) (TPU) mixtures offer the opportunity to tune water swelling capacity and diffusion rate for drugs exhibiting broadly different properties. We sought to (1) assess the range of drug diffusion rates achieved by varying hydrophilic-to-hydrophobic…

The drug in a solid dosage form must undergo dissolution before it is available for absorption from the gastrointestinal tract. Liquisolid system (LS) is a technology used for increasing aqueous solubility of the drugs, which has an important role in the dissolution and absorption phenomenon.…

The aim of this work was to evaluate gellan gum as binder in pellet formulations, with theophylline as the model drug, in comparison with polyvinylpyrrolidone (PVP). A full 32 factorial design was realized, with binder and dilu- ent factors at three levels each. Pellets were produced by the…

Flowability is a key consideration during the formulation and process development of oral solid dosage forms as it can have a critical impact on product quality. With a limited number of examples available in the literature, there is a need to better understand and share the typical flow properties…

The purpose of this study was to develop liquid and solid paediatric formulations of sodium dichloroacetate (DCA) for the treatment of congenital lactic acidosis (CLA). In this work preformulation studies on the active molecule were performed to identify those physico-chemical properties of the drug…

Incorporating poorly soluble drugs into polymeric nanoparticles is a widely investigated approach to improve their biopharmaceutical performance. Poly(DL-lactide-co-glycolide) (PLGA) nanoparticle formulations have previously been tested and recommended as drug carriers for peroral administration of…

Fast and accurate manufacturing of individually tailored solid dosage forms is one of the main challenges for personalized medicine. The use of 3D printers has recently been studied to determine their suitability for personalized drug manufacturing. In the current work, formulations free of organic…
