Deflazacort is a glucocorticoid used as an anti-inflammatory and immunosuppressant.

Deflazacort is an inactive prodrug which is metabolized rapidly to the active drug 21-desacetyldeflazacort.[1] Its potency is around 70–90% that of prednisone.[2]

It is sold in the United Kingdom by Shire under the trade name Calcort;[2] in Brazil as Cortax, Decortil, and Deflanil; in India as MOAID, Defolet(Schwartz), DFZ, Decotaz, and DefZot; in Panama as Zamen, Spain as Zamene and in Honduras as Flezacor.[3] It is not available in the United States.
