Efficacy of long-term treatment with nipradilol, a nitroester-containing beta-blocker, in patients with mild-to-moderate essential hypertension

The effects of long-term treatment with nipradilol, a nitroester-containing beta-blocker, on casual and 24-hour blood pressures were studied in 70 patients with mild-to-moderate essential hypertension. Antihypertensive effects of nipradilol on casual blood pressure were observed in 68% of patients. Nipradilol reduced pulse rates, but no bradycardia was observed. The usefulness of nipradilol in the present study was 65%. The results of ambulatory blood pressure monitoring indicated that nipradilol reduced systolic blood pressure more than diastolic blood pressure, and reduced blood pressure during waking more than during sleep. These results suggest that nipradilol is a safe and useful long-term antihypertensive drug in both young and older patients with mild-to-moderate essential hypertension. When administered twice daily, nipradilol is effective throughout a 24-hour period.
