A dihydropyridine compound of the following general formula (I) or a salt thereof: ##STR1## wherein R.sup.1 and R.sup.2, which are the same or different, each represents a C.sub.1 to C.sub.10 alkyl group, a lower alkyl group which is interrupted by oxygen atom(s), or a lower alkyl group substituted by C.sub.3 to C.sub.6 alicyclic group(s); R.sup.3 and R.sup.4, which are the same or different, each represents a lower alkyl group; R.sup.5 and R.sup.6, which are the same or different, each represents a hydrogen atom, a nitro group, a halogen atom, a lower alkyl group, a lower alkoxy group, a lower alkylthio group, a lower alkylsulfonyl group, or a lower alkylsulfinyl group; R.sup.7 and R.sup.8, which are the same or different, each represents a hydrogen atom, a halogen atom, a cyano group, a lower alkoxy group, or a lower alkanoylamino group, or R.sup.7 may combine with R.sup.8 to form a naphthyl group together with the adjacent phenyl group; A represents a single bond, a vinylene group (--CH.dbd.CH--), or a ethynylene group (--C.dbd.C--); B represents a single bond or --CH.sub. 2 O--; and m and n, which are the same or different, each represents 0 or an integer of 1 to 5. The compounds are useful for the treatment of various cardiovascular disorders, since they possess both Ca.sup.2+ -antagonistic and adrenergic beta-receptor blocking activities.
