ABSTRACT:
The present invention provides pharmaceutical compositions effective against angina-like heart and circulatory diseases containing at least one nitroxyalkylamine derivative of the general formula: ##STR1## wherein R.sub.1 is a hydrogen atom, a lower-alkyl radical, a C.sub.3 -C.sub.8 -cycloalkyl or C.sub.3 -C.sub.8 -cycloalkenyl radical, an aminocarbonyl, C.sub.1 -C.sub.6 -mono- or di-alkylaminocarbonyl radical, R.sup.2 is a hydrogen atom, a lower-alkyl radical or a C.sub.3 -C.sub.8 -cycloalkyl or cycloalkenyl radical or R.sup.2, together with R.sup.1 and the nitrogen atom to which they are attached, form a heteroaliphatic ring containing up to 6 carbon atoms, A is a valency bond or a straight-chained or branched lower-alkylene radical, in which a --CH.sub.2 -- group can be replaced by a cycloalkylene radical, B is a lower-alkylene radical, in which a --CH.sub.2 -- group can be replaced by a cycloalkylene radical and X is an --NR.sup.3 --CO-- or --CO--NR.sup.3 -- radical, in which R.sup.3 is a hydrogen atom or a lower-alkyl radical, when X is an --NR.sup.3 --CO-- radical, R.sup.3, together with the nitrogen atom and a carbon atom of the group A, bridge a heterocyclic ring containing 4 to 6 carbon atoms or R.sup.3, together with R.sup.2, A and the two nitrogen atoms, bridge a heterocyclic ring containing 3 to 5 carbon atoms; and the optically-active forms and physiologically acceptable salts thereof.
