Study to Evaluate Symptoms in Patients Treated With Nebivolol or Metoprolol Extended-Release (ER) for Hypertension
Summary
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)
Description
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.

Medical and Biotech [MESH] Definitions
Metoprolol
A selective adrenergic beta-1-blocking agent with no stimulatory action. It's binding to plasma albumin is weaker than alprenolol and it may be useful in angina pectoris, hypertension, or cardiac arrhythmias.
Bendroflumethiazide
A thiazide diuretic with actions and uses similar to those of HYDROCHLOROTHIAZIDE. It has been used in the treatment of familial hyperkalemia, hypertension, edema, and urinary tract disorders. (From Martindale, The Extra Pharmacopoeia, 30th ed, p810)
Hydrochlorothiazide
A thiazide diuretic often considered the prototypical member of this class. It reduces the reabsorption of electrolytes from the renal tubules. This results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. It is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.
Hypertension, Pregnancy-induced
A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.
Hypertension, Renovascular
Hypertension due to RENAL ARTERY OBSTRUCTION or compression.
