Angiotensin is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. It is part of the renin-angiotensin system, which is a major target for drugs that lower blood pressure

Angiotensin II increases thirst sensation (dipsogen) through the subfornical organ of the brain, decreases the response of the baroreceptor reflex, and increases the desire for salt. It increases secretion of ADH in the posterior pituitary and secretion of ACTH in the anterior pituitary. It also potentiates the release of norepinephrine ( adreniline) by direct action on postganglionic sympathetic fibers.

Can't really vote on this one as the second question doesn't have an option for just NO-haven't tried one as opposed to No help.

True, they block the conversion to Angiotension 2, but an ARB blocks the function to the muscles and blood vessels. There are a few people here that are on ARB's (Lorsartan). An ACE doesn't increase potassium levels and an ARB does. Both can increase NO levels. When you read the studies done with the idea of high Angiotension 2 levels - they use Lorsartan as the trial drug - that's an ARB.
