Abstract
The invention provides novel esters of androstadiene 17-carboxyclic acids of the formula ##STR1## wherein R' represents a hydroxyl group which is esterified with a carboxyclic acid having not more than 7 carbon atoms, R' represents a methyl group in the .alpha.- or .beta.-position or the methylene group, wherein R is H or Cl, each of X and Y represents a hydrogen, chlorine or fluorine atom, with the proviso that at least one of these substituents is one of these halogens, when R is Cl, and that Y is only Cl or F and X only Cl, when R is H and that the androstadiene-17-carboxylic acid ester group does not contain more than 11 carbon atoms. The new esters have pronounced antiinflammatory action coupled with remarkably low systemic side effects on thymus, adrenals and body weight. They are especially suitable to be used in dermatology.
