Active clinical trials for "Essential Hypertension"

The purpose of this study is to evaluate long-term safety and tolerability of once daily administration of the combination of Valsartan and Amlodipine 80/5 mg for 52 weeks in patients with essential hypertension.

Both Olmesartan (OLM)/Amlodipine (AML) combination and Hydrochlorothiazide (HCTZ) have proven to be efficacious and safe in lowering blood pressure, but may not always be sufficient. This study is to test efficacy and safety of the combination of OLM/AML and HCTZ in hypertensive patients whose blood pressure is not adequately controlled with OLM/AML alone. The following treatments will be included in the trial: OLM 40mg/AML 10mg; OLM 40mg/AML 10 mg/HCTZ 12.5 mg; OLM 40 mg/AML 10 mg/HCTZ 25 mg. The trial has four periods. The treatments that will be used are as follows: Period 1 - OLM 40mg/AML 10mg; Period 2 - OLM 40mg/AML 10mg or OLM 40mg/AML 10 mg/HCTZ 12.5 mg or OLM 40 mg/AML 10 mg/HCTZ 25 mg; Period 3 - OLM 40mg/AML 10 mg/HCTZ 12.5 mg; Period 4 - Period 3 responders: OLM 40mg/AML 10 mg/HCTZ 12.5 mg; Period 4 - Period 3 non-responders: OLM 40mg/AML 10 mg/HCTZ 12.5 mg or OLM 40 mg/AML 10 mg/HCTZ 25 mg

Study objective: To evaluate the antihypertensive efficacy, safety and tolerability of the drug after the oral administration of BR-A-657•K at 20~180mg for 4 weeks to patients with essential hypertension. To review the pharmacokinetic profile after the multiple administration and the pharmacodynamic profile regarding the renin-angiotensin system, after the oral administration of BR-A-657•K at 20~180mg for 4 weeks to patients with essential hypertension. To determine the dose for the clinical study at the next phase by analyzing the relationship between the antihypertensive efficacy and pharmacokinetic • pharmacodynamic results.

The purpose of this study is to evaluate of efficacy and safety of amlodipine plus losartan and amlodipine alone in patients with essential hypertension inadequately controlled on amlodipine monotherapy.

The purpose of this study is to investigate the efficacy and safety of Bunazosin with Valsartin compared to Doxazosin with Valsartin for patients with mild to moderate essential hypertension accompanied by metabolic syndrome.

Resistant hypertension is defined as hypertension not controlled (i.e. blood pressure not below 140/90 mmHg) with the use of adequate doses of at least three different anti-hypertensives including a diuretic. Resistant hypertension is abundant. In the ALLHAT trial 34% of patients did not reach the blood pressure goal of 140/90 mmHg. One possible mechanism of resistance is the aldosterone-escape phenomenon. During aldosterone escape, aldosterone plasma levels are normal or even elevated despite therapy with ACEIs or ARBs. The prevalence is about 30-50%. Possible reasons for aldosterone escape are alternative ways of aldosterone stimulation (hyperkalemia, adrenomedullin, ACTH), local aldosterone production or primary aldosteronism. Aldosterone has deleterious blood pressure independent effects on cardiac, vascular and renal damage. Hypothesis: Eplerenone is effective to improve hypertensive target organ damage in patients with resistant hypertension.

Efficacy, tolerability and safety of olmesartan alone or in combination with hydrochlorothiazide in the treatment of mild to moderate essential hypertension

This study is to test the efficacy and safety of the combination of olmesartan and amlodipine in hypertensive patients whose blood pressure is not adequately controlled with amlodipine alone

The purpose of this study is to evaluate of efficacy and safety of HCP1904-3 and RLD2001-1 alone in patients with essential hypertension inadequately controlled on RLD2001-1 monotherapy.

Multicenter, randomized, open-label, parallel-group exploratory study to explore the effects of azilsartan (Azirva), compared with telmisartan, on insulin resistance in participants with essential hypertension complicated by type 2 diabetes mellitus
