[The combination of nifedipine and a low sodium diet with potassium supplement in the therapy of essential arterial hypertension].

Moderate dietary sodium restriction with moderate dietary potassium supplementation was used in patients with essential hypertension who were treated with nifedipine retard by mouth every twelve hours. Combination therapy of this diet with the nifedipine retard produced a significantly greater decrease in both lying and standing blood pressure that with the drug alone. No noticeable side effects were observed.
