Active clinical trials for "Essential Hypertension"

The goal of this project is to investigate the effects that the addition of aldosterone blockade with eplerenone will have on the progression of diastolic dysfunction in patients with controlled essential hypertension.

Salt is a main environmental risk factor involved in atherosclerotic complications and in the high risk of a variety of cardiovascular (CV) diseases including hypertension, left ventricular hypertrophy (LVH), chronic kidney disease (CKD) and heart failure. The link between sodium and cardiovascular disease is complex and involves blood pressure (BP) dependent and independent mechanisms. Among the latter, inflammation is suspected to be a major effector of arterial damage brought about by the salt excess in animal models. In humans, C-Reactive Protein (CRP) associated directly with dietary salt intake in a population-based survey but such a link was not confirmed in other studies. This apparent discrepancy may depend on the observational (i.e., open to confounding) nature of these studies. Inflammatory cytokines are essential for the short term systemic response to environmental stressors. For example it is well established that TNF-α, a cytokine that modulates renin gene expression by signalling via TNF-receptor 2, exerts a protective effect for the myocardium in a stressful condition like experimental cardiac ischemia while low levels of adiponectin have a detrimental effect in the same setting. Thus, the inflammation-sodium relationship may be non-linear and severe salt restriction may actually trigger inflammation, a hypothesis suggested by the observation that biomarkers of inflammation rose in response to salt depletion in a sequential study in essential hypertensives. However, the lack of randomization in this study leaves open the question whether the observed pro-inflammatory effect was due to change in salt intake or to other, unmeasured time-dependent effect(s). With this background in mind the investigators setup a randomized, single masked, cross-over study to assess the effect of a short term very low salt diet on biomarkers of innate immunity in patients with uncomplicated essential hypertension.

The purpose of this study is to evaluate the antihypertensive efficacy and safety of Fimasartan/Hydrochlorothiazide combination 60/12.5mg~120/12.5mg in patients with essential hypertension who are not controlled by fimasartan 60mg.

This study is being done to evaluate the efficacy, safety, and tolerability of losartan potassium 50 mg (L50) + hydrochlorothiazide 12.5 mg (H12.5) + amlodipine besylate 5 mg (A5) (MK-0954E). The primary hypothesis is that L50/H12.5/A5 is more effective in lowering mean trough sitting diastolic blood pressure (SiDBP) after 8 weeks of treatment compared to L50+A5 in Japanese participants with essential hypertension who are not adequately controlled following an 8-week treatment with filter period study drug (L50+A5).

This study is being conducted to evaluate the safety of MK-0954A (L100/H12.5 mg) in essential hypertension participants who are uncontrolled with MK-954H (L50/H12.5 mg).

This study has two parts. In the first part, the efficacy and safety MK-0954E (losartan potassium 50 mg [L50] (+) hydrochlorothiazide 12.5 mg [H12.5] (+) amlodipine besylate 5mg [A5]) will be evaluated and compared to the efficacy and safety of MK-0954H (L50/H12.5) in Japanese participants. In the second part, the safety and tolerability of long-term use of open-label MK-0954E in participants with hypertension will be evaluated. The primary hypothesis is that MK-0954E is more effective in lowering mean trough sitting diastolic blood pressure (SiDBP) after 8 weeks of treatment compared to MK-954H (L50/H12.5 mg) in Japanese participants with essential hypertension who are not adequately controlled following a 8-week treatment with filter period study drug of MK-954H.

This is a clinical study evaluating the safety and efficacy of long term administration of oral BAYA1040_Nifedipine 80 mg/day (40 mg twice daily) with other antihypertensives in patients with essential hypertension who are not at target blood pressure by the combination of BAYA1040_Nifedipine 40 mg once daily and other antihypertensives.

The purpose of this study was to evaluate the dose-response relationships of azilsartan, once daily (QD) in participants with mild to moderate uncomplicated essential hypertension.

To evaluate the possible effects of atorvastatin on ambulatory blood pressure, urinary albumin excretion, insulin resistance and arterial stiffness in hypertensive patients, beyond those on lipid profile. Glycemic parameters, "novel" cardiovascular risk factors and safety parameters will be also evaluated.

The purpose of this clinical study is to evaluate and compare the efficacy and safety of Fimasartan (60mg / 120mg) with Candesartan(8mg) in patients with mild to moderate hypertension.
