Comparative Effects of Nebivolol Versus Placebo on Sodium Sensitivity of Blood Pressure in Hispanic Postmenopausal Women With Hypertension

2014-08-27 03:18:47 | BioPortfolio

Summary

2.1 Research objectives:

The objective of this randomized, placebo-controlled, 2 period crossover clinical trial is to determine the effects of nebivolol versus placebo on ambulatory blood pressure, the blood pressure response to dietary sodium loading, and renal handling of an acute sodium load in postmenopausal women with hypertension.

2.1.1 Hypothesis:

Nebivolol will result in a blunted response of blood pressure to oral sodium administration and improved handling of an intravenous sodium load in comparison with placebo in hypertensive postmenopausal women.

2.2 Research plan:

2.2.1 Study design

The study will consist of a randomized crossover trial of the effects on salt sensitivity of nebivolol. All study procedures will be carried out under the direct supervision of the Principal Investigator in the outpatient and inpatient research unit of the University of Miami Division of Clinical Pharmacology.

2.2.2 Primary endpoints:

1. Change and percentage change in systolic, diastolic and mean blood pressure by ABPM from final day of low sodium to the final day of high sodium in nebivolol versus placebo

2. Differences in renal sodium excretion in response to an acute sodium load during treatment with either nebivolol or placebo.

2.2.3 Secondary endpoints

1. Change in clinic blood pressure following 4 weeks of outpatient nebivolol versus placebo

2. Change in weight from final day of low sodium to the final day of high sodium in nebivolol versus placebo

3. Change in 24-hour sodium and potassium excretion from last day of low sodium to last day of high sodium

4. Asymmetrical dimethylarginine (ADMA)

Medical and Biotech [MESH] Definitions

A cardioselective ADRENERGIC BETA-1 RECEPTOR ANTAGONIST (beta-blocker) that functions as a VASODILATOR through the endothelial L-arginine/ NITRIC OXIDE system. It is used to manage HYPERTENSION and chronic HEART FAILURE in elderly patients.

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 due to RENAL ARTERY OBSTRUCTION or compression.

Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.

Familial or idiopathic hypertension in the PULMONARY CIRCULATION which is not secondary to other disease.
