Abstract
The disclosed invention includes corticoid-17-alkylcarbonates substituted in the 17-position, a process for their preparation and pharmaceuticals containing them. These corticoid-17-alkylcarbonates have the following formula I ##STR1## where A is CHOH in any desired steric arrangement, C.dbd.O or CH.sub.2 ; Y is H, F, or Cl; Z is H, F or CH.sub.3 ; R(1) is O-acyl, carbonylalkyl, alkylsulfonate or arylsulfonate; PA1 R(2) is branched alkyl or (CH.sub.2).sub.2-4 --OCH.sub.3 and PA1 R(3) is H or methyl. They have excellent local and topical antiinflammatory action. They are distinguished by a particularly good ratio of local to systemic antiinflammatory activity and in some cases also show stronger local antiinflammatory activities than their isomeric corticoid-17-alkylcarbonates having a linear alkyl group in the 17-alkylcarbonate moiety.
