Angiotensin II receptor antagonists (ARBs) block the angiotensin II receptors that are linked to hypertension and heart failure, mainly through vasodilation & heart remodeling inhibition.
Fainting can occur but usually baroreceptors within the aortic sinuses initiate a baroreflex such angiotensin II and norepinephrine stimulate vasoconstriction and heart rate increases to return blood flow.
At these elevated levels, angiotensin II also constricts the afferent arteriole into the glomerulus in addition to the efferent arteriole it normally constricts.
Conversely, when renin levels are low, angiotensin II and aldosterone levels decrease, contracting the extracellular fluid compartment, and decreasing blood pressure.
