Angiotensin II bolsters GFR by selectively constricting the efferent glomerular arteriolar system, increasing glomerular capillary hydrostatic pressure. However angiotensin II also increases systemic vascular tone and stimulates aldosterone release, leading to renovascular hypertension. It should be apparent that treating renovascu-lar hypertension patients with drugs that inhibit ACE or antagonize the angiotensin receptor itself can lead to a sudden drop in GFR. The administration of these drugs also provides the basis of some of the functional tests for RAS.
