Q: do arb medications for hypertension help patients with elevated catechlomines and no pheo? do they calm sympathetic nervous system activation ?

: They not act on the SNS.They usually are of no value in a pheochromocytoma or due to stress. They act on the renin-anigotensin-aldosterone system(RASS). They block the AII receptors in the blood vessels. They work if you have too much renin and do not work well if your renin is low. Google RASS for more details.
