A member asked:
Why they say that it is dangerous to take beta blockers only and before alpha blockers in pheochromocytoma treatment? is really life-threatening?
A doctor has provided 1 answer
Yes, dangerous: Hi. Non-selective beta-blockers (e.g., propranolol) block beta-2 receptors, which mediate arterial relaxation. Pheos secrete epi and norepi, which activate alpha-1 and beta receptors. If you block vasodilatory beta-2's, then the arteries will see unopposed alpha-1 stimulation, which can cause a hypertensive crisis and stroke, death, etc. Block alpha-1 receptors first!
