Metopirone

1 What is Metopirone?

Brand: Metopirone

Generic: Metyrapone

Metopirone via oral route is administered to diagnose certain health problems concerning the adrenal glands.

Located near the kidneys, the adrenal glands is the producer of cortisol, a steroid chemical that helps the body regulate illness and stress.

Taking a metyrapone test enables the doctor to know if the adrenal glands are producing the right amount of cortisone whenever the body is under stress or illnesses.

The test is done by administering metyrapone orally in prescribed doses a day before the testing is done.

The following day, blood and urine tests will be done, which will check the level of cortisol in the body. The test result is per diagnosis of the doctor.
