Towards a better understanding of the role of stabilizers in QESD crystallizations
Quasi-emulsion solvent-diffusion crystallization (QESD) is a type of spherical crystallization which can be used as a particle design method to improve the flowability and micromeritic properties of drugs or excipients. Spherical particles are generated by dispersing a solvent phase in an…

Blind-Watermarking – Proof-of-Concept of a Novel Approach to Ensure Batch Traceability for 3D…
Falsified medicines are a major issue and a threat around the world. Various approaches are currently being investigated to mitigate the threat. In this study, a concept is tested that encodes binary digits (bits) on the surface of Fused Deposition Modelling (FDM) 3D printed geometries. All that is…

Dose-independent Drug Release from 3D Printed Oral Medicines for Patient-specific Dosing to Improve…
Fused deposition modelling (FDM) 3D printing provides the ability to address individual patients’ therapeutic needs without having to change the formulation every time. This is particularly interesting for dosing and release modelling. In this study, a geometry model was developed that can represent…

Concept of Orodispersible or Mucoadhesive “Tandem Films” and Their Pharmaceutical Realization
Orodispersible or mucoadhesive films as a patient-oriented dosage form for low-dosed drugs are usually produced using solvent casting. This paper presents a modification of the solvent casting technique that aimed to divide oral films into two or more compartments.
The proposed objectives and…
