Prazosin in the diagnosis and treatment of pheochromocytoma.
In a patient with paraganglioma, severe hypertension due to high levels of plasma norepinephrine was easily controlled with prazosin hydrochloride, 6 to 8 mg/day for 19 days before surgery. A prolonged antihypertensive response to the first two 1-mg doses suggested the presence of pheochromocytoma. This experience dramatizes the remarkable effectiveness of prazosin as a postsynaptic alpha-adrenergic receptor blocker and invites further trials of the drug for both the diagnosis and treatment of pheochromocytoma.[1]References
