title: Glucose induced paradoxical serum potassium elevation exclusively in the upright posture in metoprolol treated hypertensives.
abstract: Paradoxical glucose-induced serum potassium elevation was found exclusively in the upright position in 9 patients with essential hypertension treated with metoprolol. The finding of depressed plasma aldosterone by the drug shed light only at one of the possible mechanisms leading to the unexpected changes in internal potassium balance.
