Recognised as one of the major scientific breakthroughs of the 20th century, polymerase chain reaction (PCR) is a quick and simple method to create, in a test tube, millions of copies of a given DNA segment from a complex mixture of genetic material. This method has greatly stimulated biochemical, molecular…
Cocrystals can help to address the manufacturability (flow, compaction, processability) as well as solubility/dissolution,hygroscopicity and stability properties of an active pharmaceutical ingredient (API).

Crystallography is the science underpinning crystallisation, as well as a basic understanding of atomic arrangement within solids and their resulting structures. The United Nations announced that 2014 would be the International Year of Crystallography (IYCr2014). IYCr2014 commemorates the 100th anniversary of X-ray diffraction according to Bragg’s Law (celebrated by the…

Recombinant protein production is a prerequisite and essential component of most modern small molecule drug discovery programs. Target proteins are required to underpin screening, structural and mechanistic studies providing data that drives chemical design. From the initial establishment of recombinant protein production in the pharmaceutical industry in the 1980s, systems…

Flow cytometry is an extremely useful technique for the rapid analysis of many cell types. Here, the applications of this technique for the monitoring and optimisation of microbial recombinant protein production processes are discussed.
Spray drying is one of the most remarkable technologies currently to be applied to pharmaceuticals. It is a continuous process that converts, in a single step, a liquid feed into a powder and is an ideal process when precise attributes such as particle size, morphology and stability are required. This…

Pharmaceutical products have to be of high quality with respect to a number of predefined attributes, e.g. identity and strength with respect to the active pharmaceutical ingredient (API) and the presence and levels of impurities. At least for smaller compounds, such quality control often involves chromatographic methods. The examples given…

Over the past decades, pharmaceutical drug development has undergone some significant changes, a prominent example for this being the emergence of biomolecular drugs (New Biological Entities, NBEs) such as antibodies and peptides. However, classical small molecule drugs (New Chemical Entities, NCEs) are far from being a dying species, and in…

Control strategies are often implemented when developing drugs and manufacturing biological and therapeutic products, however, increasingly they are considered important in the manufacture of sterile medicines. A control strategy for manufacturing sterile pharmaceutical products and substances sets out a documented approach and rationale taken to control product quality, efficacy and…

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…
