The phentolamine inhibition test, also known as phentolamine suppression test, is a diagnostic function test to detect autonomous catecholamine production, such as occurs in pheochromocytoma. It is carried out when the findings are unclear.
Those affected are administered phentolamine and the pheochromocytoma is detected on the basis of the drop in systolic blood pressure following the intravenous injection of phentolamine.
