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…
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…
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)…
The past quarter of a century has seen an enormous increase in the number of papers on the behaviour of the organic solid state, particularly those concerning pharmaceutical polymorphs and solvates. High profile patent cases (ranitidine hydrochloride, paroxetine hydrochloride) combined with product polymorph issues (ritonavir), all of which have carried…
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…

Pharma and BioPharma industries are aware of the impact of production processes on sustainability of business operations. To improve performance, companies have recognised that it is necessary to better understand the drivers of both costs and revenues and the actions that can be put in place to address them.

Biomedical research often involves the use of cell lines that can be cultured in a laboratory. Individual cells within such cell lines often share a similar morphology. A remarkable exception are in vitro cultured mouse Embryonic Stem Cells (mESCs) – pluripotent cells derived from the blastocyst stage of the mouse…

Powders and bulk materials are widely used in industry as raw materials, intermediates and finished products. Indeed, over 60% of the value of pharmaceutical sales worldwide is accounted for by powder formulations, typically as tablet/capsule/sachet or in the form of an inhalable powder. Whilst they are used extensively, they are…
