Understanding early mouse embryonic development using single-cell mRNA Sequencing

3 July 2014 | By René Dirks and Hendrik Marks, Department of Molecular Biology, Radboud Institute for Molecular Life Sciences (RIMLS)

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…

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

Pharmaceutical powders characterisation – the need for a multivariate approach

3 July 2014 | By Brian Armstrong and Katrina Brockbank, Freeman Technology

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…

Is risk in the eye of the beholder?

15 April 2014 | By

An effective quality risk management (QRM) process provides a key mechanism for the proactive identification and control of potential issues that may arise during product development and subsequent commercialisation1. In this context, risk is defined as the combination of the probability of occurrence of harm (or unwanted outcome) and the…

Microbiology Series: Antimicrobial delivery

15 April 2014 | By Joshua Boateng and Harshavardhan Pawar, Department of Pharmaceutical Chemical and Environmental Sciences, Faculty of Engineering and Science, University of Greenwich

Antimicrobial drugs form a significant aspect of disease therapy and are a major means of treating bacterial, fungal and viral infections. The issue of antimicrobial therapy is of current interest and clinical concern. This is mainly due to two key reasons; (i) persistent emergence of microbial resistant strains and (ii)…

Hot melt extrusion processing for the development of sustained release products

15 April 2014 | By Dennis Douroumis, Reader in Pharmaceutical Sciences at the University of Greenwich and the Director of Centre for Innovation in Process Engineering and Research

Hot Melt Extrusion (HME) has attracted increased interest for the development of pharmaceutical dosage forms over the last decade. It is a versatile processing technology which produces extrudates in the form of solid dispersions and solid solutions. Among the various applications, HME has been adopted for the development of sustained…

Excipients in medicines for children: scientific and regulatory paradigms

15 April 2014 | By Ali Al-khattawi, Postdoctoral Research Associate, Aston University / Afzal R. Mohammed, Senior Lecturer in Pharmaceutics, Aston University

There is an ongoing debate over the use of pharmaceutical excipients in medicines for children, triggered by the increased number of formulations suitable for this target patient population. Pharmaceutical excipients can be regarded as essential / necessary enablers in formulation development. These are materials other than the ‘active pharmaceutical ingredient’…

Excipient selection in biologics and vaccines formulation development

19 February 2014 | By M. Babu Medi and Ramesh Chintala, Vaccine Drug Product Development, Merck & Co, Inc and Akhilesh Bhambhani, Novel Adjuvants, Formulation and Delivery Technologies, Merck & Co, Inc.

Excipients are an integral part of pharmaceutical products and play an important role in the formulation development of both small and large molecule pharmaceuticals. The type and extent of excipient use depends on several factors, including the type of active ingredient, route of administration, dosage form, target population and indication…
