New and pharmacologically useful 17-amino-16-hydroxy-steroids of the androstane and oestrane series are disclosed having the formula I: ##STR1## and pharmaceutically acceptable non-toxic acid addition salts thereof, wherein: R.sub.1 =H or hydrocarbyl of one to six carbon atoms (preferably lower alkyl, such as methyl); R.sub.2 =H or hydrocarbyl of one to six carbon atoms (preferably lower alkyl, such as methyl); R.sub.3 =a free, esterified or etherified hydroxyl group; ring A inclusive carbon atoms 6 and 9 has one of the following configurations: ##STR2## in which R.sub.4 =a free, esterified or etherified hydroxyl group; R.sub.5 =O or H(R.sub.7), wherein R.sub.7 is a free, esterified or etherified hydroxyl group; R.sub.6 =H or methyl; and the dotted lines represent an optional double bond in 4,5- or 5,6-position; as well as the enantiomers and racemates of these steroids. The novel compounds have antiarrhythmic properties.
