Titration of nadolol in the treatment of hypertension.

An open, observer-blind, therapeutic titration trial was carried out in 28 patients with mild or moderate essential hypertension to determine the effective dose range of nadolol given once a day. 11 patients became normotensive (supine diastolic blood pressure 90 mm Hg or below) with 80 mg, 4 with 120 mg and 1 with 160 mg. The largest step in the reduction of blood pressure was achieved with the first dose step of 80 mg, and only a small, nonsignificant further decrease was obtained with higher dose levels. Thus, nadolol, unlike propranolol, has a narrow effective dose range, and this should permit a brief dose adjustment period, which would be important in improving patient compliance.
