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…

Lean, Six Sigma, people and organisations

5 September 2014 | By Dr. Stephen McGrath, Teva Pharmaceuticals Ireland (TPI)

Organisations are constantly striving to drive down costs while maintaining the quality of their products and services. In recent years, much has been written in both the academic and practitioner literature on the application of Lean principles for the elimination of waste and focusing of energies on value-creating activities.

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…

What does quality mean to you?

3 July 2014 | By

An effective quality risk management (QRM) process ensures proactive identification and control of potential issues that may arise during development and commercialisation. Where quality is defined as the degree to which a set of intrinsic properties of a drug product, its underpinning manufacturing process, and any supporting processes fulfils the…

Techniques to preserve product quality in pharmaceutical freeze drying

3 July 2014 | By , ,

In a pharmaceutical freeze drying process, it is mandatory to preserve product quality. This means that for a given formulation that has to be freeze dried, the temperature has to remain below a limit value corresponding to the eutectic temperature for a product that crystallises after freezing, with the goal…

Using self-amplifying mRNA vaccines to facilitate a rapid response to pandemic influenza

3 July 2014 | By , ,

Influenza viruses are members of the Orthomyxoviridae family and are a major cause of respiratory tract disease in humans and many animal species. There are three influenza virus types that cause human disease: A, B and C. Type A are further subtyped based on the antigenicity of the hemagglutinin (HA)…

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…
