[Methodical prerequisites in clinical pharmacology (author's transl)]

Clinical pharmacology being an experimental natural science, tries to answer clinical questions by means of thoroughly studied syntactic models. In doing so it is regularly confronted with the typical problems of any experimental science: the syntactic problem, the semantic problem, the problem of redundance. The syntactic problem is regarded as being solved by biometric means. The semantic problem reflects the developing state of scientific findings; insofar the solutions are of provisional character. To a large extent the problem of redundance seems to be a discretionary question.
