Novel, therapeutically active 21-aminosteroids of formula (I) ##STR1## with pregnane skeleton, are disclosed wherein two of X, Y and Z are a nitrogen atom each and the third one is a methine group; R.sup.1 and R.sup.2 are independently from each other, a primary amino group bearing as substituent a branched-chain C.sub.4-8 alkyl -alkenyl or -alkynyl group, or a C.sub.4-10 cycloalkyl group comprising 1 to 3 ring(s) and being optionally substituted by at least one C.sub.1-3 alkyl group; or R.sup.1 and R.sup.2 are each a spiro-heterocyclic secondary amino group containing at most 10 carbon atoms and optionally at least one oxygen atom as additional heteroatom; or one of R.sup.1 and R.sup.2 is an unsubstituted heterocyclic secondary amino group containing 4 to 7 carbon atoms and the other one is an above-identified primary amino group, an above-identified spiro-heterocyclic secondary amino group, or a heterocyclic secondary amino group containing 4 to 7 carbon atoms and substituted by at least one C.sub.1-4 alkyl group; and n is 1 or 2, as well as their acid addition salts and pharmaceutical compositions containing these compounds.
