A technique is described for measuring an index of cardiac output, total and individual renal plasma flow, cortical and juxtamedullary nephron flow non-invasively in man with a single injection of 123I-o-iodohippurate. Ibopamine, a dopamine analogue, was administered orally, 200 and 600 mg, in a double-blind, placebo-controlled cross-over study in 6 healthy subjects. No change in pulse, blood pressure, cardiac output, urea, creatinine or electrolytes was seen. Ibopamine reduced effective renal plasma flow and cortical nephron flow and increased urine flow significantly. This may be due to differential vasoconstrictor and vasodilator effects on the two populations of nephrons. Indoramin, and alpha-1 postsynaptic adrenoceptor blocker, was administered orally, 50 mg, in a double-blind, placebo-controlled cross-over study in 14 healthy young males. No change in pulse, cardiac output, urea, creatinine or electrolytes was seen. Indoramin significantly reduced upright but not supine blood pressure and significantly increased effective renal plasma flow. Cortical nephron flow and juxtamedullary nephron flow tended to rise. Plasma renin activity was significantly elevated although there was no change in urinary sodium output. The effect of drugs on intrarenal blood flow distribution may be relevant to the management of essential hypertension.
