Dopamine and prostaglandin A1 were infused intravenously in 4 patients with the hepatorenal syndrome, in 1 patient with acute tubular necrosis, and 1 patient with cortical necrosis. Large doses of prostaglandin A1 decreased arterial blood pressure preventing increase in dosage; in contrast, high doses of dopamine elevated blood pressure. When the two drugs were administered conjointly, much larger doses of each agent could be administered without change in arterial blood pressure. Significant improvement of renal function was not observed in any of these critically ill patients during or within 24 hours after dopamine and prostaglandin A1 administration. This study demonstrated that extremely large doses of these vasodilating agents can be safely administered conjointly.
