简要总结
Study is to evaluate the effect of Nebivolol to treat high blood pressure compared to an already approved drug, Metoprolol ER with background treatment of Amlodipine.
详细描述
Open-label, single center study consisting of a 2 to 4 week baseline washout phase, a 12-week Amlodipine background treatment phase followed by a 4-week Low Dose Nebivolol/Metoprolol Treatment phase and a 4-week High Dose Nebivolol/Metoprolol Treatment Phase.
