The biopharmacy focuses on the relationships between the fate of the drug in the body, the time course of drug action and intensity and the physico-chemical properties of the drug as well as the dosage form. The evaluation needs the pharmacokinetic interpretation of processes in the body (drug absorption, distribution, metabolism and excretion) as well as qualitative and quantitative description of the time course changes.
During the practical training students perform tasks using in vitro and in vivo methods and bioanalytical procedures. Furthermore they learn the mathematical calculations of pharmacokinetic parameters and computer simulations.
