Compounds of the formula ##STR1## wherein R.sup.1 is a C.sub.1-8 alkyl group or a C.sub.3-7 cycloalkyl group, and R.sup.2 is a C.sub.1-6 alkyl group or a C.sub.3-6 cycloalkyl group and the D-homo analogues thereof having the group --CO.sub.2 R.sup.2 (wherein R.sup.2 is as defined above) at the 17.alpha..beta.-position, and acid addition salts thereof have activity as antidysthythmic agents and may be applicable for the treatment of dysrthymias in humans or animals. The compounds may be provided in the form of compositions in admixture with pharmaceutical carriers and excipients and may be prepared by a variety of processes known for producing steroids of this type. The invention also provides intermediates for the preparation of the compounds of formula (I) wherein R.sup.2 and/or R.sup.1 are replaced with hydrogen atoms, and processes for the preparation of such intermediates.
