Abstract
The efficacy and acceptability of 5 mg nebivolol once daily, a long-acting, vasodilating cardioselective beta blocker that additionally facilitates the L-arginine/nitric oxide system, was assessed in a double-blind, randomized trial in comparison with 20 mg nifedipine retard twice daily in patients with essential hypertension. At 2 weeks of treatment, nebivolol was significantly more effective. Thereafter, both drugs effectively and similarly lowered systolic and diastolic pressures without orthostatic effect. Nebivolol had a trough-to-peak antihypertensive effect ratio of 90%. Nifedipine gave the expected side effects of headache, flushing, and edema. Nebivolol was well tolerated. Nebivolol slightly but significantly lowered heart rate. Neither drug adversely affected plasma levels of lipids.
