Solid/Semi-Solid Dosage

Tim Freeman of Freeman Technology explains how new analytical technologies have influenced quality criteria and standards for the uniformity of dosage units, and why more accurate systems are leading to greater focus on tablet scoring.

When splitting unscored tablets, the main concerns relate to API dosage control and the potential modification of time-release characteristics. PTE speaks with tableting experts Thierry Menard, Lab Manager, And Bruno Villa, President, both at Medelpharm, about how manufacturers are approaching the challenges.

Tablet splitting is a new area of focus for regulators. The FDA tells PTE more about the challenges in this area.

GlaxoSmithKline recently developed a novel technology for the formulation of modified-release tablets. The authors describe the route from development to commercialization.

Particle-engineering technologies, such as crystal design for crystallization and producting cocrystals, particle-size reduction, and amorphous solid dispersions, help to optimize delivery of a drug.

As part of an ongoing collaboration into tabletting science, I Holland and the UK's University of Nottingham have launched a two-year programme to investigate the cause of tabletting sticking.

In our tablet coating process, we are losing up to 15% of our coating solution in each processing run. What can we do to prevent this problem in order to reduce waste and increase our cost efficiency?
