The present invention relates to aminoalkoxyphenyl derivatives of formula: ##STR1## and its N-oxide and pharmaceutically acceptable salts, in which: B represents a--S--, --SO-- or --SO.sub.2 -- group, R.sub.1 and R.sub.2, which are identical or different, each denote hydrogen, a methyl or ethyl radial or a halogen atom, A denotes a straight-or branched-alkylene radical having from 2 to 5 carbon atoms or a 2-hydroxypropylene radial in which the hydroxy is optionally substituted by a lower alkyl radical, R.sub.3 denotes an alkkyl radical or a radical of formula: --Alk--Ar in which Alk denotes a single bond or a linear- or branched-alkylene radical having from 1 to 5 carbon atoms and Ar denotes a pyridyl, phenyl, 2,3-methylenedioxyphenyl or 3,4-methylenedioxyphenyl radical or a phenyl group substituted with one or more substituents, which may be identical or different, selected from halogen atoms, lower alkyl group or lower alkoxy groups, R.sub.11 denotes hydrogen or a lower alkyl, phenyl, diphenylmethyl, benzyl or halogenobenzyl radical, R.sub.4 denotes hydrogen or an alkyl radical, or R.sub.3 and R.sub.4 when taken together denote an alkylene or alkenylene radical having from 3 to 6 carbon atoms and optionally substituted with a phenyl radical or optionally interrupted by ##STR2## R represent hydrogen, an alkyl radical, a cycloalkyl radical, a benzyl radical or a phenyl radical optionally substituted with one or more substituents, which may be identical or different, selected from halogen atoms and from lower alkyl, lower alkoxy or nitro groups, are described. The compounds of the invention possess exceptional pharmacological properties, especially calcium transport inhibitory properties, as well as bradycardic, hypotensive and antiadrenergic properties.
