Brief Summary:
The purpose of this study was to compare the tolerability of nebivolol to metoprolol ER in a general population of patients with mild to moderate hypertension receiving hydrochlorothiazide (HCTZ)

Condition or disease Intervention/treatment Phase
Hypertension Drug: Metoprolol ER Drug: Nebivolol Phase 3

Detailed Description:
This study was 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. Up-titration 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.

Official Title: Tolerability of Nebivolol Compared With Metoprolol ER in Patients With Mild to Moderate Hypertension Taking Hydrochlorothiazide (HCTZ)
Actual Study Start Date : October 31, 2007
Actual Primary Completion Date : January 2, 2008
Actual Study Completion Date : January 2, 2008


Arm Intervention/treatment
Experimental: Nebivolol
Nebivolol 5 mg, 10 mg or 20 mg
Drug: Nebivolol
Nebivolol once daily, oral administration

Active Comparator: Metoprolol ER
Metoprolol ER 50 mg, 100 mg or 200 mg
Drug: Metoprolol ER
Metoprolol ER once daily, oral administration




Primary Outcome Measures :
  1. Change From Baseline in the Patient Symptoms Questionnaire (PSQ) Derived Score [ Time Frame: Measurements occured over a 14 week period, from Visit 2 (Week -2) to Visit 10 (Week 12) ]
    The PSQ contained 44 possible symptoms rated from 0 (no discomfort) to 5 (extreme discomfort).


Secondary Outcome Measures :
  1. Peripheral Blood Pressure (BP) [ Time Frame: Measurements occured over a 18 week period, from Visit 1 (Week -4) through Visit 11 (Week 14) ]
  2. Pulse Rate [ Time Frame: Measurements occured over a 18 week period, from Visit 1 (Week -4) through Visit 11 (Week 14) ]
