Active clinical trials for "Hypertension"

The purpose of this study is to determine whether sapropterin (an oral analogue of tetrahydrobiopterin) could have a role in the treatment of portal hypertension secondary to liver cirrhosis. Sapropterin or placebo will be given for two weeks in patients with liver cirrhosis and clinically significant portal hypertension. Systemic and hepatic hemodynamics studies will be performed at baseline and after the intervention to assess the effect of sapropterin.

This is a Phase 2, Placebo Controlled, Double-Blind, Randomized, Clinical Study to Determine Safety, Tolerability and Efficacy of Pulsed, Inhaled Nitric Oxide (iNO) Versus Placebo as Add-on Therapy in Symptomatic Subjects with Pulmonary Arterial Hypertension (PAH).

We hypothesized that the increase in MAP from 65 mmHg to patients' usual level improved sublingual microcirculation.

Evaluation of the intraocular pressure (IOP) lowering effect of two iStent inject devices versus medical therapy in eyes of subjects with primary open-angle glaucoma, pseudoexfoliative glaucoma, or ocular hypertension naïve to medical and surgical therapy.

Physiology of migraine involving renin-angiotensin systems (RAS) has been implicated. Ramipril is a broadly-used angiotensin-converting enzyme inhibitor. The investigators attempt to test the efficacy of ramipril on the prophylaxis of migraine attacks.

This study was aimed at testing the hypothesis that supplementing a meal with dark chocolate, which holds potent antioxidant properties, might attenuate the postprandial increase in the hepatic venous pressure gradient (HVPG, clinical equivalent of portal pressure) in patients with cirrhosis

This is a four-part study of the safety, tolerability, and PK profile of sodium nitrite inhalation solution (AIR001) of ascending multiple doses (Part A) and of escalating doses with steady-state sildenafil (Part B) to healthy male and female subjects, as well as assessment of the safety and tolerability of multiple doses of AIR001 to patients with pulmonary arterial hypertension (part C) with a single dose PK study of AIR001 utilizing three different nebulizers (Part D).

The purpose of this study is to determine whether the relaxation response is more effective than attention control in reducing blood pressure and medication dosage in elderly adults with isolated systolic hypertension.

Effect of increasing doses of olmesartan medoxomil and olmesartan medoxomil/hydrochlorothiazide on blood pressure in patients with hypertension

The purpose of the study is to investigate the safety and efficacy of adding simvastatin to the current conventional treatment regimen for the management of pulmonary hypertension.
