Active clinical trials for "Hypertension"

The purpose of this research study is to determine whether atenolol or controlled release carvedilol lower blood pressure in the body as effectively as in the arm. Blood pressure measured in the aorta, a large blood vessel carrying blood away from the heart, may be a better measure of the harmful effects of high blood pressure on the body's organs. In the past, blood pressure has only been measured in the arms. However, blood pressure in the arms may not accurately reflect the blood pressure in the aorta and thus may mislead doctors treating high blood pressure. For this reason, we are testing whether two different medications for blood pressure, both in a class called beta blockers, have similar effects on blood pressure in the arm and aorta.

The purpose of this study was to describe the safety and IOP-lowering efficacy of Travoprost New Formulations compared to TRAVATAN® and to vehicle in patients with open-angle glaucoma or ocular hypertension.

To evaluate the effectiveness of diet management with a losartan based titration regimen versus losartan based titration regimen alone on blood pressure reduction in hypertensive patients.

This study is being done to see if the blood pressure lowering effect of an approved drug nebivolol is comparable to that of another approved drug carvedilol for the treatment of hypertension in patients who have coronary artery disease.

To evaluate the effect of three doses of oral sildenafil (20, 40 and 80 mg three times a day [TID]) on exercise capacity, as measured by the 6-Minute Walk test, as well as the safety and tolerability, after 12 weeks of treatment in subjects with pulmonary arterial hypertension who are aged 18 years and over. To investigate the plasma concentration-effect relationship and to determine the population pharmacokinetic (PK) parameters.

To compare the antihypertensive efficacy of the combination irbesartan/hydrochlorothiazide (HCTZ) using either a usual or an active elective titration regimen. The main efficacy criteria will be the change in mean Systolic Blood Pressure (SBP), measured at doctor's office with an automatic device, after a 10-week treatment period in hypertensive patients insufficiently controlled by monotherapy.

The purpose of this study is to demonstrate the safety and efficacy of the Rheos Baroreflex Hypertension Therapy System in patients with refractory hypertension.

The purpose of this research study is to determine whether a simple blood test measuring a hormone called renin can better determine which first drug would be most effective in controlling blood pressure, in comparison with the more traditional approach recommended by JNC7 (Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure).

The purpose of this study was to assess patient preference regarding ocular comfort of AZARGA® compared to COSOPT® after one week instillation of each study medication.

The goal of this study is to determine if aerobic exercise or progressive muscle relaxation is associated with changes in cardiovascular health, brain function, and cognition.
