Isoflupredone Acetate is an anti-inflammatory drug used in veterinary medicine. It is a corticosteroid with both glucocorticoid and mineralocorticoid activity and has been shown to increase the frequency of severe hypokalemia in healthy cows.

ChEBI: 9alpha-Fluoro-11beta,17alpha,21-trihydroxypregna-1,4-diene-3,20-dione 21-acetate is a corticosteroid hormone.

Isoflupredone acetate is a potent glucocorticoid and like other glucocorticoids can be used for its antiinflammatory or immunosuppressive effects. Labeled indications for isoflupredone include: adjunctive treatment of bovine ketosis, alleviating pain and lameness associated with musculoskeletal conditions, acute hypersensitivity reactions, adjunctive treatment of overwhelming infections with severe toxicity, shock, supportive therapy in the treatment of stress conditions (e.g., surgery), dystocia, retained placenta, inflammatory ocular conditions, snakebite and parturient paresis.
In horses, isoflupredone has been used parenterally to reduce inflammation associated with recurrent airway obstruction (RAO, “heaves”, COPD).
While the drug could be used in small animals, it is recommended to use other glucocorticoid agents instead, where there has been more experience and other approved products for dogs and cats are available.

The ITSL for Isoflupredone Acetate is 0.01 μg/m3 based on annual averaging.
