To test whether dopaminergic mechanisms can modulate the humoral and renal effects of atrial natriuretic factor (ANF), seven untreated, mildly hypertensive patients without complications were given a placebo (saline for 60 min) followed by a low dose of ANF (0.005 microgram/kg per min), or D-sulpiride (0.05 mg/kg per min), a specific dopamine-1 antagonist, or ANF + D-sulpiride at the same doses, for 60 min. The sequence of the three treatments was random, with a 72-h interval between treatments. The ANF infusion, which increased plasma ANF within the physiological range, significantly increased urinary sodium excretion, fractional sodium excretion and haematocrit; it reduced plasma aldosterone and tended to reduce plasma renin activity without changing blood pressure, the heart rate, renal plasma flow or the glomerular filtration rate. D-Sulpiride, when given alone, significantly increased mean blood pressure and reduced absolute and fractional sodium excretion without changing the heart rate, glomerular filtration rate, renal plasma flow, haematocrit, plasma renin activity or plasma aldosterone. When infused with D-sulpiride, ANF did not change absolute or fractional sodium excretion or haematocrit. This study provides evidence that dopaminergic mechanisms play a role in the natriuretic and plasma volume effects of a synthetic human ANF analogue infused at a low dose in patients with essential hypertension.
