Output (English): The present invention relates to modulation of calcium channels in vascular and cardiac tissues i.e. the use of compounds of the general formula I. This modulation process increasing density of the calcium channels in vascular and cardiac tissues without changes in inotropic or pressor response comprises administering of pharmaceutically active amounts of the compounds of the general formula I, in which the groups Re1 and Re2 represent independently on each other a hydrogen atom, an alkyl group containing 1 to 4 carbon atoms, -CO-Alk, wherein Alk represents an alkyl group having one to six carbon atoms, -CHi2Ar or -CO-Ar, wherein Ar represents phenyl or a substituted phenyl; the Re2 group is selected from a group comprising pyrrolidine, hexamethyleneimino and piperidino; or pharmaceutically acceptable salts thereof.
