Dihydropyridines of the formula:-
wherein R' is alkyl or alkoxyalkyl, wherein R2 and R3 each is alkyl, wherein benzene ring A bears one or more substituents selected from halogeno, cyano, nitro, trifluoromethyl and alkyl or bears the substituent =N-0-N= attached to the 2-and 3- positions, wherein Ar is phenyl, naphthyl, tetrahydronaphthyl, indanyl or indenyl which is unsubstituted or which bears one or more substituents, or Ar is a 5- or 6-membered heterocyclic ring containing 1, 2 or 3 heteroatoms selected from oxygen, nitrogen and sulphur, which ring is saturated or unsaturated, which ring is unsubstituted or bears one or more substituents, and which ring may also be fused to a benzene ring, wherein p is 0 or 1, wherein X is -O- or -NH-, and wherein Y is straight-or branched-chain alkylene of 2 to 12 carbon atoms which may optionally be interrupted by one or two groups selected from oxygen, sulphur, imino, substituted imino, phenylene, substituted phenylene, pyridylene, cycloalkylene, 1,4-piperazinediyl, 1-4-piperidinediyl and amido groups, or an acid-addition salt thereof; processes for their manufacture and pharmaceutical compositions containing them. The compounds possess either beta-adrenergic blocking or calcium ion slow channel blocking properties, or both such properties, and may be used in the treatment of hypertension.
