Active clinical trials for "Hypertension"

The purpose of this study is to compare the short-term mean 24-hour intraocular pressure control, 24-hour blood pressure effect and safety of Latanoprost/Timolol fixed combination given once in the evening with placebo once in the morning versus timolol maleate 0.5% given twice daily in patients with ocular hypertension and primary open-angle glaucoma.

Post-operative pulmonary hypertension is a risk factor for right ventricular failure and an increasing cause of morbidity and mortality in patients undergoing high-risk cardiac surgery. Several treatments have been used to treat and reduce post operative pulmonary hypertension. Unfortunately none of these treatments are approved for use in this condition and only one (inhaled nitric oxide) is specific enough to pulmonary hypertension to not cause dangerous low blood pressure in the rest of the body. Sadly, inhaled nitric oxide is difficult and expensive to use, and can cause lung damage. Sildenafil citrate is quite specific to the lung vessels, is easy to administer and does not easily cause low blood pressure in other areas of the body. We hypothesize that oral sildenafil 12.5mg will decrease the baseline (pre-dose) mPAP by at least 20% compared with a placebo.

The purpose of the study is to measure the effect of the amlodipine/atorvastatin combination pill in reducing both elevated blood pressure and cholesterol levels to levels suggested by guidelines

This study is comparing the effectiveness of web-based care management to either telephone-based care management or internet access alone, in patients with poorly controlled diabetes mellitus.

The primary objective of this study is to describe the effect of TRAVATAN 0.004% Ophthalmic Solution on aqueous humor dynamics in subjects with a clinical diagnosis of open angle glaucoma (OAG) or ocular hypertension (OHT).

To evaluate the effects of two different antihypertensive medications in the drug class of beta-blockers on control of glucose in Type II diabetic patients with high blood pressure.

The purpose of this study is to compare the effects on blood pressure of a daily intake of a flavonoid-rich cocoa drink with that of the same drink from which the flavonoids have been largely extracted.

The purpose of this study is to investigate the efficacy and safety of Bunazosin with Valsartin compared to Doxazosin with Valsartin for patients with mild to moderate essential hypertension accompanied by metabolic syndrome.

The study compares the efficacy of an aggressive versus a moderate initial antihypertensive regimen to reduce blood pressure in patients with Stage 2 hypertension. Additionally, the study examines the effects of blood pressure reduction on the levels of high sensitivity hsCRP. Although the main goal is to determine the overall effect of blood pressure reduction on hsCRP levels, analysis will also evaluate whether an aggressive antihypertensive regimen is more effective than a moderate one in reducing hsCRP levels.

The purpose of this study is to evaluate the effects of nebivolol on blood pressure and heart rate in African American patients with hypertension.
