Abstract
Novel steroids having the general formula: ##SPC1## Wherein X and Y are independently selected from hydrogen and fluorine, X being selected from hydrogen and fluorine when Y is hydrogen and X being fluorine when Y is fluorine, Z is selected from hydroxyl and esterified hydroxyl preferably containing a maximum of 12 carbon atoms, if any, in the esterifying group, R is selected from straight and branched hydrocarbon chains having 2-10 carbon atoms; processes for the preparation of said steroids; compositions containing said steroids; and method of treating inflammation therewith. The steroids are physiologically active compounds possessing anti-inflammatory activity. This application claims pharmaceutical compositions and method of treating employing the novel steroid steroisomeric mixtures.
