Calcium antagonists may increase glomerular filtration rate and renal plasma flow by antagonizing the intrarenal effects of angiotensin II and/or norepinephrine. We prospectively studied the effects of amlodipine, a once-a-day dihydropyridine calcium channel antagonist, in 19 patients with essential hypertension. Studies were performed after 4 weeks of placebo and 6 weeks of amlodipine therapy, and included the assessment of systolic and diastolic BP, renal clearances of inulin and p-aminohippurate, and determination of body fluid composition. Systolic and diastolic BPs were reduced following 6 weeks of amlodipine monotherapy. In spite of significant decreases in mean arterial pressure, there were increases in inulin clearance (+ 13%), and p-aminohippurate clearance (+ 19%). Filtration fraction was not changed. Renal vascular resistance was decreased (-25%). Total blood volume, extracellular fluid volume, and total body water and body weight were not changed. We conclude that amlodipine therapy has the potential to reverse renal abnormalities encountered in the hypertensive state.
