Tablet ejection: A systematic comparison between force, static friction, and kinetic friction
The magnitude of the frictional forces during the ejection of porous pharmaceutical tablets plays an important role in determining the occurrence of tabletting defects. Here, we perform a systematic comparison between the maximum ejection force, static friction coefficient, and kinetic friction…

Multi-component mixing and demixing model for predictive finite element modelling of pharmaceutical…
A set of numerical methods is described that allows predictive finite element method (FEM) simulations of the compaction of multi-component pharmaceutical powder formulations across the entire range of compositions. An automated parametrisation procedure was used to extract density-dependent…

Designing starch-based fenofibrate formulations using the melting method
Fenofibrate (FNF) is used to treat hyperlipidemia. However, FNF is a poorly water-soluble drug, and the dosage of commercial products is relatively high at 160 mg in a Lipidil® tablet. Therefore, this study aimed to develop an FNF-solid dispersion (SD) that solubilizes and stabilizes FNF. The…

Trends in amorphous solid dispersion drug products approved by the U.S. Food and Drug Administration…
Abstract
Forty-eight (48) drug products (DPs) containing amorphous solid dispersions (ASDs) have been approved by the U.S. Food and Drug Administration in the 12-year period between 2012 and 2023. These DPs comprise 36 unique amorphous drugs. Ten (10) therapeutic categories are represented, with…

Evaluation of binders in twin-screw wet granulation – Optimization of tabletability
Abstract
The influence of hydroxypropyl cellulose type (HPC-SSL SFP, HPC-SSL), concentration (2 %, 3.5 %, 5 %) and filler (lactose, calcium hydrogen phosphate (DCP)/microcrystalline cellulose (MCC)) on twin-screw wet granulation and subsequent tableting was studied. The aim was to identify the…

The effect of glidant on the tabletting behavior of common pharmaceutical excipients
Abstract
Glidant used for the purpose of powder flowability enhancement is well known within the pharmaceutical industry to improve tablet manufacturing. Despite the widespread use of glidant for this purpose, the effect of glidant on the effect of tableting behavior is not well studied. To address…

Easy Tableting with Natural Disintegrants
Evaluation of a new disintegrant mixture from natural resources
Introduction
Tablet disintegration is most often required to divide a tablet into suitably small sub-units that facilitate achievement of the desired drug dissolution rate. While semi-synthetic or synthetic super-disintegrants are…
