Acute renal effects of new beta-adrenergic receptor site blocking agents on renal function.
The effects of two new beta blockers on renal function have been studied. There were significant decreases in urine flow, urea clearance, sodium and chloride excretion rates after acute administration. Fractional excretion of sodium (FeNa) fell significantly but did not continue to fall during chronic administration. Blood pressure and plasma renin activity decreased significantly after two months' therapy. These findings suggest that beta blockers in patients with unstable cardiovascular function increase the need for concomitant diuretic therapy.
