What is Metopirone?

Metopirone is no longer available in the United States.

Metopirone is used as a diagnostic agent to test the function of the pituitary gland. This drug works by stopping the production of corticosterone and cortisol. This in turn forces the pituitary gland to produce corticotropin. The production of corticotropin leads to an increase in the body's production of certain chemicals. Those chemicals are excreted in the urine where they are measured to determine how well the pituitary gland is working. Metopirone is the brand name for the active ingredient metyrapone. Metopirone is no longer available on the market in the US.
