It is used in combination with calcipotriene hydrate, a synthetic vitamin D analogue, for the topical treatment of plaque psoriasis in adult patients. It has a role as an antipsoriatic. It is a steroid ester, an 11beta-hydroxy steroid, a 20-oxo steroid, a fluorinated steroid, a propanoate ester and a 3-oxo-Delta(1),Delta(4)-steroid. It is functionally related to a betamethasone."}]
