Allow the student to deepen and understand the techniques of pharmacological investigation applied in the phase of research and development of drugs (functional studies, binding, biochemical, holistic and reductionist tests) and to develop the ability to use the acquired knowledge. At the end of the course the student will be able to propose the experimental approaches to be adopted in the characterization of drugs or xenobiotics and to correctly interpret, critically, the results of experiments and studies on scientific articles for the preparation of reports and exposures for the future preparation for the discussion of the degree thesis.
