Pharmaceutical Applications Compendium PURITY AND IMPURITY ANALYSIS
APPLICATION OF CHROMATOGRAPHY AND
MASS SPECTROMETRY IN PHARMACEUTICAL
PURITY AND IMPURITY ANALYSIS
Accurate assessment of product quality requires robust analytical methods.
To remain competitive, drug development and quality control programs must find
efficient and effective ways to develop new analytical methods and to transfer
and optimize existing procedures. Increased regulatory attention on the control
of impurities (e.g., much lower thresholds for genotoxic impurities) has fueled
the need for analytical procedures that al ow significantly lower detection limits.
This in turn requires more sensitive instruments and places higher demands
on selectivity, since many additional impurities may be present at lower
concentration ranges. 
UHPLC offers significant advantages in analytical performance, speed,
sensitivity, and resolution. Today's labs must also col aborate with global
partners using a variety of instruments. As a result, flexibility in method
development and transfer has become a key component of success in the
pharmaceutical industry. The application of various mass spectroscopy (MS)
detectors to genotoxic impurity analysis has enabled breakthrough detection
limits of as little as a few hundred ppm. MS-based methods general y provide
additional robustness compared to techniques such as UV alone, due to their
high specificity and sensitivity.
What's Inside? This applications compendium has a number of practical examples that demonstrate how Agilent can help you in developing cost-effective methods for purity and impurity analysis, reducing analysis time and solvent consumption while remaining compliant with pharmacopeia guidelines. Example applications are provided that demonstrate accurate analysis of trace level impurities through the use of Agilent's highly sensitive LC, LC/MS, GC, GC/MS and SFC solutions.
We have also included a number of additional resources that provide good information related to purity and impurity profiling. They can be found listed as "Other resources" in the pages that follow.

SSTMP Posters 168 Alveolar echinococcosis: in vitro studies and experimental investigations in vivo identify potential novel treatment option A Hemphil [1] [1]Institute of Parasitology, University of Bern, Bern, Switzerland For the chemotherapy of cystic (CE) and alveolar echinococcosis (AE), albendazole and mebendazole are presently used for the treatment of non-surgical cases and as a supplementary treatment prior and post-surgery. However, in AE these benzimidazoles do not appear to be parasiticidal in vivo. In addition, failures in drug treatments as wel as the occurrence of side effects have been reported, leading to discontinuation of treatment or to progressive disease. New drugs are needed to cure AE and CE, which must be regarded as neglected diseases. Compounds that are currently being considered to represent novel chemotherapeutical treatment options include broad-spectrum anti-infective or anti-cancer drugs, drugs that interfere in the Echinococcus signal ing pathways, and drugs identified through in silico approaches exploiting the E. multilocularis genome information. Prerequisites to perform efficient in vitro screenings are, (i) optimized large scale in vitro metacestode culture systems, and (ii) reliable assays that al ow higher throughput primary drug testing against metacestodes. In addition, access to a large col ections of potential y interesting compounds is important. More recently, in vitro screening in our laboratory has lead to the identification of several drugs or drug classes, most notably mefloquine-, ozoid- and pentamidine-derivatives, which show interesting capacities to kil the metacestodes. Studies in the mouse model have demonstrated the efficacy of oral application of the anti-malarial compound mefloquine in vivo, and the pentamidine-derivative DB1127, demonstrating that these drugs, or derivatives thereof, could serve as a supplement to the currently very limited arsenal of anti-echinococcal compounds. In addition, investigations have been carried out that lead to the identification of a mefloquine-target in Echinococcus and explore the mechanism of action of mefloquine in the metacestode stage.
