Abstract

Benzoylguanidines of the formula I ##STR1## where R(1) or R(2) is equal to R(6)--S(O).sub.n -- or R(7)R(8)N--O.sub.2 S-- and the other substituent R(1) or R(2) is in each case equal to H, F, Cl, Br, I, alkyl, alkoxy or phenoxy, R(6)--S(O).sub.n or R(7)R(8)N-- and R(6) is equal to alkyl, cycloalkyl, cyclopentylmethyl, cyclohexylmethyl or phenyl, R(7) and R(8) are equal to alkyl or phenylakyl or phenyl, and in which R(7) and R(8) may also together be a C.sub.4 -C.sub.7 chain, and in which R(7) and R(8), together with the nitrogen atom to which they are bonded, may be dihydroindole, tetrahydroquinoline or tetrahydroisoquinoline system, and where R(3), R(4) and R(5) are equal to hydrogen or alkyl, or R(3) and R(4) are together an alkylene chain or R(4) and R(5) are together an alkylene chain, and where n is equal to zero, 1 or 2 and their pharmaceutically tolerable salts are outstanding antiarrhythmics.
