Active clinical trials for "Hypertension"

A ONE YEAR SAFETY STUDY FOR PATIENTS WHO COMPLETE STUDY VAA489A2201.

A phase 3, randomized, double-blind, placebo-controlled study to assess safety and efficacy of ambrisentan in subjects with pulmonary arterial hypertension.

Randomized controlled trial of CORFIS Programme. The study objectives are as follows: To determine the efficacy of a community based multiple risk factors interventional strategy (CORFIS) for a treatment period of 6 months in patients on treatment for HT, DM or HL. The intervention shall consist of a purpose design and systematically organized disease management program that employ multi-faceted interventions incorporating various specific measures to maximize both clinician (as investigator) adherence with treatment guideline and patient adherence with treatment.

The purpose of this study is to determine whether the Herculink Elite Renal Stent System is safe and effective in the treatment of renal artery stenosis in patients with less than optimal angioplasty results and uncontrolled hypertension. CAUTION: The Herculink Elite Renal Stent System Is An Investigational Device. Limited by Federal (U.S.) Law to Investigational Use Only.

The purpose of thie study is to compare the safety and IOP-lowering efficacy of AL-37807 Ophthalmic Solution 0.05%, 0.1% and 0.2% dosed QD AM to Xalatan dosed QD PM and Vehicle in patients with open-angle glaucoma or ocular hypertension

This prospective chronotherapy trial will investigate the potential differing efficacy of ramipril in doses from 5 to 10 mg/day when administered, as a monotherapy either upon awakening from nighttime sleep or at bedtime, to diurnally active patients with grade 1 or 2 essential hypertension, who will be evaluated by 48-hour ABPM before and after pharmacologic intervention. The benefits from this trial may be extremely important, taking into account the high prevalence of non-dipping among patients with essential hypertension the need for a proper 24-hour BP control with particular emphasis on the regulation of nighttime resting BP mean the lacking information on the administration-time dependent effects on BP of ramipril, a widely used ACEI in doses of 5-10 mg/day.

The primary objective of this study is to evaluate efficacy, arterial stiffness measured by Pulse Wave Velocity (PWV) of Losartan potassium group compared to Carvedilol group after 24 weeks of treatment in patients with the essential hypertension.

Sildenafil is a phosphodiesterase-5 inhibitor that has been approved for the treatment of pulmonary arterial hypertension with orphan drug designation. Sildenafil modulates the nitric oxide (NO) pathway in the vessel wall. Since this pathway is impaired in pulmonary arteries of patients with pulmonary hypertension (PH) associated with chronic obstructive pulmonary disease (COPD), we hypothesized that sildenafil might improve pulmonary hemodynamics and increase exercise tolerance in this condition. However, in COPD sildenafil may also impair gas exchange due to the inhibition of pulmonary hypoxic vasoconstriction. The research project is aimed to evaluate these effects. It is a prospective, randomized, double-blind study to evaluate the acute effects of a single dose of 20 or 40 mg of sildenafil on gas exchange and pulmonary hemodynamics. Subjects: 20 patients (10 in each group). Measurements: pulmonary hemodynamics, arterial blood gasses and ventilation-perfusion distributions; at rest and during sub-maximal exercise.

The AC-065A302 (GRIPHON) study is an event-driven Phase 3 study to demonstrate the effect of selexipag on time to first morbidity or mortality event in patients with pulmonary arterial hypertension.

Although the aetiology of SSc-PAH remains elusive, vascular dysfunction seems to be the initial event and statins through their vasculoprotective effect might be of value in the treatment armamentarium of PAH related to SSc. The aim was to assess the efficacy of rosuvastatin in ameliorating vascular dysfunction and in the management of SSc-related PAH.
