Trilostane is an inhibitor of 3β-hydroxysteroid dehydrogenase used in the treatment of Cushing/’s syndrome. It was withdrawn from the United States market in April 1994. However, it was recently approved in 2008 for the treatment of Cushing/’s disease (hyperandrenocorticism) in dogs. It is also the first drug approved to treat both pituitary- and adrenal-dependent Cushing/’s in dogs. This prescription drug works by stopping the production of cortisol in the adrenal glands.
