title: [Preclinical research--toxicology].
abstract: The different steps of the toxicological testing of new drugs are shortly described. Furthermore it is discussed that only 60-70% of the drug induced adverse reactions in man can be predicted by the experimental methods being available at present. Special problems exist in evaluating the results of reproductive-toxicological, carcinogenicity and mutagenicity tests. These problems are illustrated by some experimental and clinical examples.
