Freeze Drying


The obstacle to developing an optimum placebo formulation for pharmaceutical freeze drying

18 January 2019 | By ,

Scale-up of pharmaceutical freeze-drying processes is cost and time consuming due to Quality by Design (QbD) requirements and novel compound costs or availability. The application of placebo formulations offers a promising way to improve drug development activities and save resources. Furthermore, placebos are used as a reference in clinical trials.…

Market leaders in temperature controlled microscopy and established manufacturers of advanced freeze drying microscopes, Linkam Scientific Instruments, report on the work of Dr Henning Gieseler from the Friedrich-Alexander University (FAU) Erlangen-Nuremberg on his research and development activities in the field of freeze drying for the pharmaceutical industry.

Quality control of freeze-dried oral formulations; challenges when developing novel approaches for the delivery of poorly-soluble drugs

22 August 2017 | By ,

A common obstacle encountered in the early stages of drug development is the formulation of poorly water-soluble drugs (PWSDs). One effective approach to improve the dissolution of PWSDs is to render such drugs into their amorphous or disordered form. However, amorphous materials are both physically and chemically unstable, and tend…

The importance of being small: miniaturisation of freeze drying equipment

18 August 2017 | By ,

Developmental activities for freeze-dried products are dictated by the limited availability and high cost of newly developed active compounds, and by Quality-by-Design requirements. Laboratory-scale freeze dryers used for formulation and process development show an excessive variety of designs and instrumentation concepts, making scale-up activities a challenge. The development of miniaturised…
