Urea-substituted benzoylguanidines, process for their preparation, their use as pharmaceutical or diagnostic, and pharmaceutical containing them There are described benzoylguanidines of the formula I STR1 where R(1), R(3) or R(4) is --NR(6) C=X NR(7)R(8); X is oxygen, sulfur, R(6), R(7) and R(8) are H, (perfluoro)alk(en)yl, where R(7) and R(8) can also together be 4 or 5 methylene groups, the substituents R(1) to R(5) remaining in each case are H, Hal, (fluoro) alk(en)yl, CN, NO2, NR(16)R(17). On account of their pharmacological properties, the compounds are outstandingly suitable for use as anti-arrhythmic pharmaceuticals having a cardioprotective component for the prophylaxis and treatment of infarction as well as for the treatment of angina pectoris, the compounds also inhibiting or strongly reducing, in a preventive manner, the pathophysiological processes in association with the occurrence of ischemically induced damage, in particular in association with the elicitation of ischemically induced cardiac arrhythmias. They are obtained by reacting a compound of the formula II. STR2 in which L is a leaving group which can readily be substituted nucleophilically, with guanidine.
