Efficacy of nitrendipine as baseline antihypertensive therapy.

To determine whether calcium antagonists might be used alternatively to beta-blockers in antihypertensive therapy, we investigated if monotherapy with oxprenolol (160-320 mg/day) and nitrendipine (20-40 mg/day) were equally effective on clinical casual blood pressure (BP), ambulatory BP monitoring (Remler), and BP during mental challenge (video game). In a prospective randomized long-term study, 60 white male civil servants (mean +/- SD = 43 +/- 6 years) with mild essential hypertension only were treated for at least 4 months. Average BP before therapy was 149 +/- 11/97 +/- 11 mm Hg. The antihypertensive effect was not different between the two groups (19/14 versus 21/12 mm Hg). Both groups did not differ in BP at rest, in BP during mental challenge (141 +/- 7/109 +/- 5 versus 146 +/- 9/112 +/- 8 mm Hg, NS), and average ambulatory BP monitoring at work (122 +/- 12/81 +/- 17 versus 132 +/- 14/79 +/- 17 mm Hg, NS), which was identical with the clinical casual BP. Thus, nitrendipine can effectively be used in long-term baseline antihypertensive monotherapy.
