The invention concerns aralkyldiamine derivatives of the general formula (I) which have an antiarrythmic action, methods of preparing them and drugs containing them. In the general formula (I), R1 is a hydrogen atom or a benzoyl group in which the phenyl group may be substituted by a halogen atom, a nitro group, an amino group, an alkyl or alkoxy group with up to four C-atoms, a phenoxy group or a benzoyl group; R2 is a hydroxymethyl, aminomethyl, aminocarboxymethyl or aminooxycarboxymethyl group; R3 and R4, which may be the same or different, are hydrogen atoms, alkyl, cycloalkyl, alkenyl, alkinyl or hydroxyalkyl groups with up to 6 C-atoms, alkoxyalkyl, alkylthioalkyl or dialkylaminoalkyl goup s with up to 9 C-atoms or phenylalkyl or phenoxyalkyl groups w ith up to 6 C-atoms in the alkyl part of the group and with a ph enyl group which may be substituted by an alkyl or alkoxy group with up to 3 C-atoms, and n is a whole number between 1 and 8. |
