Resocortol butyrate is a corticosteroid which has a high intrinsic glucocorticoid activity. Its mineralocorticoid and progestational activity is very low. Resocortol butyrate has local and systemic glucocorticoid effects. The expression of these effects depends on the mode of application and the dosage applied. After topical application on the skin, a local anti-inflammatory effect is seen, which is accompanied by a moderate and reversible adrenal suppression at higher doses. After oral administration in dogs few systemic effects were observed. Resocortol butyrate was marketed under the brand name Pruban as the topical cream for the treatment of acute localised moist dermatitis in dogs. It was discontinued.
