Can HPLC assay methods really be considered quality critical tests?

5 September 2014 | By

Analytical method specificity is assessed using ICH (International Conference on Harmonisation) Q2 (2005). Although, certain methods are not specific enough for their intended purposes, they may have other advantages. Both titrimetric and UV (Ultra-violet spectroscopy) assays are non-specific, but have superior precision (ca. 0.1-0.5% RSD (Residual Standard Deviation)) compared with…

Engineering cells and proteins – creating pharmaceuticals

5 September 2014 | By Marco Casteleijn & Dominique Richardson, University of Helsinki

Pharmaceutical biotechnology is big business; it currently consists of 1/6 of the total volume of the pharmaceutical market and continues to grow steadily. Expression of therapeutic proteins is mainly done in living cells, although ‘cell free protein synthesis’ (CFPS) or ‘in-vitro transcription translation’ (IVTT) is beginning to emerge as an…

Particle characterisation in drug delivery

5 September 2014 | By Driton Vllasaliu and Ishwar Singh, University of Lincoln

The use of materials in nano-scale dimensions is proving to be a promising approach to overcome drug delivery challenges. ‘Nanomedicine’ technologies are gradually achieving commercial success and reaching the clinic. Sub-micron nanocarriers have the potential to ferry the therapeutic to its site of action and in this process overcome the…

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…
