Novel methodologies for determining the mineral content of complex multivitamin tablets

5 September 2014 | By Ryan Gosselin & Nicolas Abatzoglou, Pfizer Industrial Research Chair, University of Sherbrooke / Philip Quinn, Pfizer Industrial Research Chair, University of Sherbrooke and Process Analytical Sciences Group, Pfizer Canada / Joanny Salvas & Jean-Sébastien Simard, Process Analytical Sciences Group, Pfizer Canada

Pharmaceutical product manufacturing is a conservative environment because of the obligations to abide by rigorous operation protocols aimed at insuring the highest possible product quality. A relatively recent initiativeguidance, from the U.S. FDA (Food and Drug Administration) has encouraged innovation and development of PATs (Process Analytical Technologies) for improved process…

NMR – Recent developments for isotope profiling

3 July 2014 | By

Fraudulent misrepresentation, substitution or imitation of premium products has always been a problem for both the regulatory authorities and the pharmaceutical industry. The task of finding and preventing counterfeit products is particularly challenging1,2. Several analytical techniques are available to help characterise pharmaceutical compounds: physical profile; X-ray diffraction; infrared spectroscopy; mass…

Thus the combination of complex physical properties of powders and numerous environmental variations, such as humidity, illustrate why powder processing is so challenging.

The central role of excipients in drug formulation

18 April 2013 | By Pascal Furrer, Pharmacist

Active substances are rarely administered alone. For example, levothyroxine, a synthetic form of the thyroid hormone, indicated in the treatment of hypothyroidism, is administered at a very low dosage, ranging from 15 μg to 200 μg. These very small amounts of powder mean that it is not possible to manufacture…
