Pressor Effects of Norepinephrine After Drastic Reduction of Sodium Intake
The mechanisms whereby dietary sodium restriction leads to decreased arterial blood pressure is obscure. Previously reported studies of patients with arterial hypertension showed a lessened pressor response to norepinephrine after sodium restriction. In the present investigations, reduction in pressor response to norepinephrine during the low sodium period was observed only occasionally; sodium restriction decreases blood pressure in some hypertensive patients by other unknown mechanisms.
