Abstract

9 alpha ,21-dihalo-11 beta ,17 alpha -dihydroxy-6-fluoro-16 alpha -methylpregna-1,4-diene- 3,20-dione 17-esters of the formula <IMAGE> in which X is chlorine or fluorine, X' is bromine or chlorine, and Ac is an acyl group derived from a carboxylic acid, are distinguished by high local antiinflammatory activity with a reduced systemic effect, for which reason they can be used in medicine to alleviate and control inflammatory states. They are obtained by conventional elimination of hydrogen chloride from a corresponding 1,2-dichloro compound.
