Active clinical trials for "Hypertension"

The purpose of this study is to determine the safety, tolerability and efficacy of Amlodipine and Olmesartan medoxomil among Hypertensive Filipino patients.

Nitro Oxide (NO) inhalation was recognized as an effect treatment of Neonatal Persistent Pulmonary Hypertension (PPHN), while the safety of NO long term application was under investigation. Several research suggested too much NO2 was generated in the lung after long term (> 72h) use of NO inhalation, which cause bad effects on PS production. Sildenafil was proved to be effective to PPHN as NO. This medication has a similar clinical effect but need monitoring of blood pressure. The possible hypotension effect restrict the dosage of sildenafil, which limit the usage of sildenafil in severe PPHN. But we recommend sildenafil to The purpose of the study was to establish if NO continued with sildenafil has the same effect as single NO inhalation.

Hypertension (high blood pressure) can often cause neurological worsening in patients with stroke, intracerebral hemorrhage and subarachnoid hemorrhage. Intravenous infusion of nicardipine (Cardene) for control of hypertension is FDA approved. The disadvantage of Nicardipine IV drip is the relative large volume of fluid needed (up to 150 cc/hr). The purpose of this study is to evaluate safety and efficacy of double or triple concentrated peripheral intravenous (IV) Nicardipine.

The purpose of this study is evaluate the effect the inspiratory muscle training on the functional capacity of patients with pulmonary hypertension.

The purpose of this study is to determine the effects of spironolactone on collagen markers in a large number of patients with pulmonary hypertension. In addition, safety and tolerability of spironolactone, an aldosterone receptor antagonist, in patients with pulmonary arterial hypertension, will be determined.

This is an open label, randomized, interventional study indented to find the efficacy of different treatment regimens in treatment of pulmonary hypertension secondary to lung disease and/or hypoxia.This is to find out when to start combination therapy (sildenafil plus bosentan) in treatment of pulmonary hypertension secondary to lung disease and/or hypoxia.

In this research study, the goal is to find out if a currently FDA-approved medication called Tekturna(Aliskiren) along with the addition of Vitamin D will lower blood pressure and improve heart function in the African American population. High blood pressure occurs earlier in life in African Americans, is more severe, and is associated with greater organ damage in relation to uncontrolled hypertension. Having low levels of Vitamin D is also very common in the African American population. Research has shown that there may be a link between low Vitamin D levels and the ability of high blood pressure medications to be fully effective.

The purpose of this trial are to evaluate the reduction of urinary albumin excretion by an angiotensin receptor blocker (ARB), valsartan, in comparison with a calcium channel blocker (CCB), amlodipine, in Japanese hypertensive patients with type 2 diabetes mellitus and microalbuminuria under strict blood pressure control, and to compare the additional effects of an ARB or a CCB in combination with angiotensin-converting enzyme (ACE) inhibitor treatment.

The purpose of this study is to determine the effect of potassium chloride and potassium bicarbonate on blood pressure and also to determine whether increasing potassium intake has beneficial effects on the surrogate markers of target organ damage in cardiovascular disease, as well as on bone health.

This is a clinical study comparing the physiologic effects of two hypertonic solutions (mannitol, hypertonic saline) with a particular emphasis on changes in cerebral blood flow in patients with intracranial hypertension following serious traumatic brain injury (TBI).
