More than ever, drug makers need to be fleet and flexible-and they need their software to be the same.
Single-enantiomer drugs represent an increasingly large share of new chemical entities, leading to approaches in asymmetric synthesis.
The use of viral vectors as gene delivery and vaccine vehicles has developed rapidly during the last two decades owing to several viral properties. Viruses can infect cells efficiently, often have a broad tissue tropism and can achieve very high levels of either stable or transient transgene expression. Furthermore, their intrinsic immune-stimulatory properties can have adjuvant effects during the treatment of cancer or infectious disease and, importantly for manufacturing scale-up, some viruses can be grown to very high titre (.1012 particles/mL). The development of robust production procedures is essential to move therapeutics that utilize viral vectors into clinical trials, and to make them cost effective for market supply. Here, we describe some of the aspects of production that must be considered and optimized when producing virus vectors on an intermediate or large scale. By drawing examples from our experience of vector production, we show that upstream and downstream processes must be designed..
The trend towards developing pharmaceutical products and their manufacturing processes in tandem supports optimized production. Such developments rely on gathering process-relevant information at an early stage and being able to draw on past and current processing experience. Here, we discuss how powder rheometers can make a real difference in building a database of powder properties and removing subjectivity.
Can high-resolution sound velocity measurements be used as an analytical tool?
The aim of this study was to validate the automated clean-in-place (CIP) system installed on a capsule filling machine to determine its ability to adequately eliminate contaminants. The results obtained from the proposed cleaning validation trial showed that all the soluble tracer was removed after the washing procedure. At the end of the CIP procedure, the discharged water had the same pH, phosphate content and total organic content as the supplied water. Lack of cross-contamination in the product was also demonstrated and a recovery trial highlighted the complete elimination of the tracer from the machine.
Before any information technology solution can be installed, a company must decide whether applications are going to reside on individual computers at each employee's workstation, on servers within or outside of an organization, or on a vendor's website.
Chronotherapeutic drug delivery systems (CRDDS) have been recognized as potentially beneficial to the chronotherapy (timeoptimized therapy) of widespread chronic diseases that display time-dependent symptoms.
Informatics solutions can help change data into useful and accessible information.
High-performance liquid chromatography (HPLC) is a powerful tool for the enantioselective separation of chiral drugs. However, the selection of an appropriate chiral stationary phase (CSP) and suitable operating conditions is a bottleneck in method development and a time- and resource-consuming task. Multimodal screening of a small number of CSPs with broad enantiorecognition abilities has been recognized as the best strategy to achieve rapid and reliable separations of chiral compounds. This paper describes the generic screening strategy developed at Johnson & Johnson Pharmaceutical Research and Development to successfully develop enantioselective HPLC methods for chiral molecules of pharmaceutical interest.
Tablets prepared from mefanamic acid spherical crystals were shown to exhibit better physical properties than those made from mefenamic powder.
This article reviews sources of excipient variability, including raw materials and processing, both of which may vary from supplier to supplier and from plant to plant for a single manufacturer.
A risk-based approach is recommended for analytical method comparability for HPLC assay and impurities methods.
The authors introduce the idea of asymmetrical tolerance intervals as an aid in fully assessing product performance relative to product or process requirements.
There have been significant advances, especially in understanding the role of carrier properties on the aerosol performance of the API.
Cells function as highly accurate quality control (QC) machines to ensure that only correctly folded proteins are released into the physiological milieu to perform their designated functions. The efficient removal of damaged or incorrectly folded/misfolded proteins at the correct time keeps a cell viable and functioning.
There are many different approaches for assessing process parameter criticality, and assessing which process parameters have a significant impact on critical quality attributes (CQAs) is a particular challenge. Including an unimportant process parameter as a critical process parameter (CPP) in a control strategy can be detrimental. The authors present a statistical approach to determine when a statistically significant relationship between a process parameter and a CQA is large enough to make a practically meaningful impact (i.e., practical significance).
The author suggests a route for nanotechnology's future in the pharmaceutical industry.
While the Gulf region has already become well-known for its globally accepted infrastructure, and large projects in tourism and other service areas, major investments in healthcare or pharmaceuticals have failed to develop as well.
Lipid-based drug delivery systems - such as liposomes, micro-and nanoemulsions, self-emulsified drug delivery systems, and solid lipid micro-and nanoparticles - are becoming more popular because lipid materials are easily characterized, contain a high range of well-defined/tolerated surfactant molecules and can be developed for several administration routes.
Recent technology improvements have made acrylics the preferred system for the aqueous enteric coating of tablets
This article describes how rapidly disintegrating tablets containing a large quantity of an intensely bitter drug were successfully developed with a suitable level of masking, tablet hardness, disintegration property, dissolution profile and mouth feel.
The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) recently closed consultation on its draft guidance, ICH Q10 Pharmaceutical Quality System. If all goes to plan, adoption could come as soon as Spring 2008.
When drugs are encapsulated, electrification (the electrostatic charge of the capsule) may sometimes cause problems, such as capsule adhesion during transportation or dispersion of the capsule content in the filling process.
Is consolidated distribution the key to combating counterfeit drugs and parallel imports?
The miniaturization of preclinical safety assessment studies using a microfluidic chip system and optical microscopy can help reduce compound requirements, time, and costs in formulation development.
Use of in-process particle size analysis has enabled pharmaceutical scientists and process engineers to track the progress of a granulation process and detect its endpoint.
Roof exhaust systems that incorporate mixed-flow impeller technology promote energy savings and cost containment.
Raman spectroscopy has become a commonly used technique for physicochemical analysis that possesses many advantages over other analytical techniques. It is a very attractive characterization tool, not least because it enables measurements in water. However, very few examples of its application in an aqueous environment exist in literature. This paper provides some recent applications of Raman spectroscopy in pharmaceutical material and process characterization when water is present.
