The invention concerns new 4-aminopyridazines of the general formula I ##STR1## in which R.sup.1 denotes an R.sup.2 --SO.sub.2 --O-- or R.sup.2 --SO.sub.2 --NR.sup.3 -- group in which R.sup.2 denotes a cycloalkyl residue, an unsubstituted or substituted aryl or heteroaryl residue, R.sup.3 denotes a hydrogen atom, an alkyl or alkyloxyalkyl group which can be unsubstituted or substituted once or several times by hydroxy groups wherein the hydroxy groups can be substituted by alkyl, hydroxyalkyl, alkyloxyalkyl, hydroxyalkyloxyalkyl or alkylcarbonyl groups and wherein in each case two vicinal hydroxy groups can be linked together by alkylidene groups, as well as hydrates, solvates and physiologically tolerated salts thereof. The invention also concerns the optically active forms, racemates and mixtures of diastereomers of these compounds, processes for their production and pharmaceutical agents containing these compounds having a thrombin-inhibiting action.
