The zebrafish is a promising vertebrate model organism in early drug discovery and development. Translation of pharmacological findings to higher vertebrates requires quantification of the underlying pharmacological and (patho)physiological processes. In this thesis, we therefore developed and integrated innovative experimental and computational methods for the successful quantification of 1) the internal exposure over time after waterborne drug treatment, 2) disease dynamics and drug-induced changes therein, and 3) between-species differences in disease mechanisms. The state-of-the-art methods that we developed included nanoscale blood sampling, sensitive LC-MS/MS methods for drugs and their isomers and metabolites, and three-dimensional microscopy, integrated with non-linear mixed effects modelling to quantify the pharmacological processes in this small vertebrate. This multidisciplinarity enabled quantification of internal drug exposure-response relationships, contributed to positioning the zebrafish in the preclinical drug development pipeline, and inspired continuous collaborations between experimental and computational scientists.
