Active clinical trials for "Hypertension"

The purpose of this study is to see how much study drug is in the blood of children with pulmonary arterial hypertension (PAH) after dosing to establish the correct dose for further clinical research.

This is an open-label, nonrandomized extension to study AC-066A301. The study will assess safety and tolerability of ACT-385781A while providing a means for continuing treatment after ending participation in study AC-066A301.

The purpose of this study is to investigate the effects of iron supplementation in patients with pulmonary arterial hypertension and iron deficiency.

To evaluate the efficacy and safety of fixed-dose combination of nebivolol and valsartan compared to monotherapy and placebo in patients with stage 1 and stage 2 hypertension.

The aim is to evaluate the effect of treatment with Continuous Positive Airway Pressure (CPAP) device on clinic and ambulatory blood pressures (BP) of 200 resistant hypertensive patients with moderate-severe obstructive sleep apnea syndrome (OSAS).

This study will evaluate the efficacy and safety of either bimatoprost 0.01% ophthalmic solution (Lumigan®) alone or bimatoprost 0.01% ophthalmic solution (Lumigan®) and brimonidine tartrate 0.1% ophthalmic solution (Alphagan® P) in combination in patients previously treated with latanoprost 0.005% ophthalmic solution monotherapy who require additional intraocular pressure (IOP) lowering medication.

Sildenafil citrate slightly reduces blood pressure in treated hypertensives patients. However, it is unknown if the simultaneous use of sildenafil plus, at least, 3 classes of antihypertensive agents in patients with resistant arterial hypertension may have a synergic effect on the patients blood pressure. Moreover, sildenafil improves the endogen nitric oxide effects. The nitric oxide is an important signaling molecule in the body that contributes to vessel homeostasis by inhibiting vascular smooth muscle contraction and growth. Hypertension often impaired NO pathways. Nitric oxide is produced by an enzyme, called nitric oxide synthase (NOS3), that show some genetics variants, which means that this enzyme can be different from person to person. Therefore, the objective of the present study is to examine the influence of a genetic variant (known to affect NOS3 levels) in sildenafil acute effects on hemodynamic and cardiovascular function. The investigators hypothesis is that individuals with the genetic variant associated to higher levels of NOS3 will have more benefits from sildenafil treatment.

The investigators hypothesise that pre-application of Qutenza® patches to the skin may reduce pain at the site of Remodulin® SC infusion (sited 1 to 2 weeks later at the site of Qutenza pre-application), in which case it would greatly improve the quality of life of the patients, and enable many more to continue with this treatment. It may also provide new information to support the use of Qutenza® patches for preventing and reducing pain produced by inflammation. The present study will explore the efficacy of single applications of Qutenza® (capsaicin 8% patch) in reducing site pain caused by continuous SC infusion of Remodulin®, in pulmonary arterial hypertension patients, as assessed by changes in subjective pain rating score and/or pain and sensory testing.

The purpose of this study is to compare the effects of a direct renin inhibitor (DRI), aliskiren, on the urinary albumin excretion in hypertensive patients with type 2 diabetes under strict blood pressure control with angiotensin receptor blocker (ARB).

The purpose of this study was to demonstrate that the intraocular pressure-lowering efficacy of Travoprost 0.003% is equivalent to TRAVATAN® in adult patients with open-angle glaucoma or ocular hypertension.
