Phentolamine mesylate is the drug of choice for managing hypertensive episodes in clients with pheochromocytoma. It blocks both alpha-1 and alpha-2 adrenergic receptors, preventing the effects of excess catecholamines released by the tumor. Propranolol may be used to control heart rate and tremors but should be given only after alpha blockade to avoid unopposed alpha-adrenergic stimulation. Methysergide and amrinone are not indicated for managing hypertensive episodes in clients with pheochromocytoma.
