Metopirone (SU-4885) has been widely used as a test of pituitary ACTH reserve. Problems in the interpretation of the test remain, both in the definition of the normal response and in the meaning of the abnormal response.
A comparison was made between the urine and plasma levels of both 17-hydroxycorticoids (Porter-Silber chromogens) and 11-desoxycorticosteroids (11-DOCS) in healthy subjects and patients with and without pituitary disease. The response to Metopirone could be interpreted best by the changes in urine 11-DOCS excretion, the normal response being a rise of at least 7 mg/day above the control level. The use of P-S chromogen
