Abstract
Stabilized, 17-substituted hydrocortisone containing compositions and methods of manufacture are disclosed. Isomerization of the hydrocortisone component of topical steroid compositions is markedly reduced by including an omega-6 acid component in the form of a free acid or as a compound such as an ester. Specifically disclosed are methods for preventing the isomerization of hydrocortisone 17-butyrate into hydrocortisone 21-butyrate through the use of safflower oil.
