Pheochromocytoma and Ca++ channel blocker.


This is a case report of a 57-year-old woman who was diagnosed as suffering from pheochromocytoma on the basis of serum catecholamine levels, the results of abdominal echography and CT scanning. Her fluctuating blood pressure was treated successfully by intravenous administration of diltiazem. Diltiazem elicits a marked reduction in vascular resistance. There was no evidence that diltiazem affects catecholamine secretion levels, as reported by others for nifedipine.
