This key module in the MSc Pharmacology and Toxicology programme brings together core and novel aspects of toxicology in the context of the development of new medicines. Topics include major organ toxicities, pharmacogenetics, development of in vitro test systems, nanotoxicology and computational/systems toxicology. This builds on local research strengths (e.g. Centre for Drug Safety Science) and strong links with the pharmaceutical industry and regulatory agencies. The module includes research connected lectures and seminars, from leading academic researchers based at the University of Liverpool, as well as external speakers. The two module assessments are aimed at writing reports on topics covered in the first and second half of the module, respectively.
