Abstract
The invention comprises 2a -methyl-9a -fluoro-11b , 17a - dihydroxy - 4 - pregnene - 3, 20 - dione 17 - acylate, wherein the acyl radical is that of a hydrocarbon carboxylic acid containing 1-12 carbon atoms inclusive, and a process for the preparation thereof by reacting 2a -methyl-9a -bromo - 11b , 17a - dihydroxy - 4 - pregnene - 3,20-dione 17-acylate with a mild base to obtain the corresponding 2a -methyl-9b ,11b -epoxy-17a -hydroxy-4-pregnene-3,20-dione 17 - acylate and reacting the 9,11-epoxy-compound thus obtained with hydrogen fluoride to obtain the corresponding 2a - methyl - 9a - fluoro - 11b , 17a - di - hydroxy - 4 - pregnene - 3, 20 - dione 17 - acylate. Specification 810,859 is referred to.ALSO:Pharmaceutical compositions having progestational and anti-inflammatory activity comprise 2a - methyl - 9a - fluoro - 11b ,17a - didroxy - 4 - pregnene - 3,20 - dione 17 - acylates, and a pharmaceutical carrier with or without coacting antibiotics and germicides. They are administered orally, parenterally or topically as tablets, powders, capsules, pills, solutions, emulsions, suspensions, syrups, elixirs, ointments, creams, and lotions. Specification 810,859 is referred to.
