The exaggerated natriuresis and diuresis of hypertensive patients to a hypertonic saline infusion was investigated to determine the importance of the beta adrenergic nervous system and cardiac hemodynamics. Six hypertensive and four normotensive patients received a hypertonic saline load (100 ml of 5% saline/m2 body surface area) before and after beta adrenergic blockade. During the 3 hr after the hypertonic saline loading the hypertensive patients excreted 79% (129 of 158 mEq Na), and the normotensive patients excreted 37% (60 of 162 mEq Na) of the load; whereas after 2 weeks of oral propranolol (120 to 340 mg daily), the hypertensive
