Study to Evaluate Symptoms in Patients Treated With Nebivolol or Metoprolol Extended-Release (ER) for Hypertension
Tolerability of Nebivolol Compared With Metoprolol ER in Patients With Mild to Moderate Hypertension Taking Hydrochlorothiazide
The purpose of this study is to compare the tolerability of nebivolol to metoprolol ER in a populatoin of patients with mild to moderate hypertension also receiving hydrochlorothiazide (HCTZ)
This study is an 18-week study to evaluate the tolerability of nebivolol compared to metoprolol ER in outpatients with mild to moderate hypertension taking HCTZ. It is a multi-center, randomized, double blind (DB), active-control, parallel-group study, starting with a 4-week HCTZ run-in phase, followed by a 12-week DB treatment phase. Patients meeting the entry criteria at the end of run-in are randomized to one of two treatment groups, nebivolol or metoprolol ER. Uptitration of dose of study drug will occur if needed during the first 4 weeks of the DB phase, after which there is an 8-week stable-dose period of treatment. A 2-week double-blind withdrawal phase follows, during which tapering off study drug occurs.
