Abstract
Dihydropyridines of the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.5 and R.sup.6 can be hydrogen or various halogen or organic radicals, PA0 R.sup.4 is an optionally substituted hydrocarbon radical, PA0 A is a direct bond, a C.sub.1 -C.sub.20 -alkylene chain or a C.sub.2 -C.sub.20 -alkenylene chain, which chains are optionally interrupted by O or S PA0 X is O or S, and PA0 Y is a direct bond, O, S, --NH--or--N-alkyl with 1 to 8 C atoms PA0 or a pharmaceutically acceptable salt, are useful as cardiotonic agents for improving heart contractility, antihypotonic agents, for lowering the blood sugar level, for detumescing mucous membranes and for influencing the salt and/or liquid balance.
