Compounds of the formula:
and pharmaceutically acceptable salts thereof wherein R is aryl or heteroaryl; R' and R2 are each independently C1-C4 alkyl. 2-hydroxyethyl or 2-methoxyethyl; R3 and R4 are each independently H or C1-C4 alkyl or taken together with the nitrogen atom to which they are attached, they form a pyrrolidinyl, piperidyl, morpholino, piperazinyl or N-(C1-C4 alkyl)piperazinyl group; R5 is C1-C4 alkyl which may be optionally substituted by OH or C1-C4 alkoxy; Y is a C2-C6 alkylene bridge which may be branched and which may optionally be substituted by OH, or alternatively, R5 may be a C1-C4 alkylene bridge linked to a carbon atom in Y to form. with the nitrogen atom to which they are attached, a piperidine ring; Q is CH or N;each X is independently C1-C4 alkyl, C1-C4 alkoxy, halogen or CF3 and m is 0 or an integer of from 1 to 3; are cardiovascular agents having both calcium antagonist and alpha1-antgonist activity and are useful for the treatment of hypertension, heart failure and angina.
