There is a wide portfolio of tablet presses on the market. The press design is depending on the application area. While in R&D only small quantities of powder formulations are available, high throughputs must be generated in the production area. It is a challenging task to assess the critical quality attributes for large scale productions already during the formulation development stage.

There is a wide portfolio of tablet presses on the market. The press design is depending on the application area. While in R&D only small quantities of powder formulations are available, high throughputs must be generated in the production area. It is a challenging task to assess the critical quality attributes for large scale productions already during the formulation development stage. Even though academia and industry are investigating and implementing scale-up of tablet production since decades, no consensus is found on how to do it best. This is due to the wide variety of formulations which are compressed. Also, the final tablet shapes and sizes do differ tremendously. From mini tablets in low volume to standard tablets in high-volume, a wide range must be covered depending on the application.

The aim of this study was to evaluate alterations of force–displacement data upon temperature rise as an indicator for changed excipient properties. The tablet press was equipped with a thermally controlled die to imitate the heat evolution from tableting on an industrial scale. Six predominantly ductile polymers with a comparably low glass transition temperature were tableted at temperatures ranging from 22-70°C.
In conclusion:

On this article you will find how pharmaceutical companies can improve the efficiency of their entire product development and drug commercialisation process with the ever-rising costs of bringing a drug to market. A well-known source of bottlenecks, delays, and technical setbacks is process scale-up, where production moves from the laboratory to full-scale GMP manufacturing

The present works demonstrated from a study to predict capping on biconvex tablets from a wide range of products (18 formulations, 8 of which presenting capping), using the properties characterized on defect-free flat-faced tablets (tensile strength, solid fraction, elastic recovery, etc.). The study is available in the PAPERS section.

Tablets are by far the most widely used pharmaceutical dosage form, followed by capsules. Tablets are cost-effective, stable, and easy-to-administer. The main advantage is that compression allows for high speed manufacturing with a very high level of quality control. As such, tablets have been popular among pharmacists since the emergence of the tablet compression industry in the mid-20th century. Despite this long history, the industry is continually improving this dosage form to advance patient care. Meanwhile, the processes and equipment it uses to manufacture these products are also advancing.

The purpose of this new study was to evaluate the processability and dissolution behavior of HPC GXF ((Klucel® GXF) and a recently introduced type of hot-melt extrudable HPMC (Affinisol®) in extended-release metformin hydrochloride formulations using twin-screw melt granulation. The powder blends were then granulated at different temperatures, then tableted. Rheological studies (steady steer rate viscosity and rotation rheometry) as well as dissolution studies were then performed. Full paper ...

This new study from the University of Braunschweig explores the microstructure of tablets, analyzable thanks to X-ray microtomgraphy (XMT).
This helps to get a deeper understanding of their properties: mechanical strength, component distribution etc. XMT measurements are then compared with other methods used to characterize APIs. Access the paper HERE.

There are numerous tablet defects: chipping, picking & sticking, cracking, lamination & capping to name a few.
Lamination & capping often occur during scale-up and are main issues in our industry. Capping is the partial or complete removal of the crown of a tablet from the main body, while lamination is the separation of a tablet into two or more distinct layers. However, those 2 phenomenon share similar causes...
