A 1,4-dihydropyridine derivative having hypotensive activity is represented by the formula (I):
in which one of R, and R2 represents an alkyl group or a group of the formula (II):
in which R5 represents an alkoxy group or a substituted or unsubstituted heterocyclic group and n represents 0 or an integer of 1 - 3, and the other of R, and R2 represents a group of the formula (III):
in which R6 represents a substituted or unsubstituted aralkyl group and R7, R8, R9, R10, R11 and R12 are the same or different groups and each represertts hydrogen or an alkyl group, and two alkyl groups may be attached to one carbon atom on the piperidine ring. When R, is an alkyl group and Ra is an unsubstituted aralkyl group, at least one of R7, Rs, Rs, R10, R11 and R12 represents an alkyl group. Also disclosed are pharmaceutically acceptable acid addition salts of compound (I).
