Active clinical trials for "Hypertension"

OBJECTIVES: I. Assess the effect of lactulose on the circadian rhythm of plasma melatonin in patients with subclinical hepatic encephalopathy. II. Assess the intrasubject variability of circadian melatonin levels and neuropsychological tests. III. Assess which elements of the neuropsychological test battery show the response to lactulose.

Rationale: Hypertension is an important risk factor of cardiovascular disease, especially in patients with type 2 diabetes mellitus (T2DM). A relatively recent development for the treatment of hypertension is the use of breathing exercises. The investigators' previous studies with a breathing device did not show any positive results. However, these studies and other trials investigating the effects of breathing devices had not a double-blind design. Therefore, the investigators want to perform a randomized, double-blind, controlled trial in a population of T2DM patients. Objective: To determine the effect of a device slowing breathing (Resperate©) on office systolic blood pressure (SBP) in diabetic patients with treated hypertension with moderate BP control. Study design: A randomized, double-blind, controlled trial. Study population: Patients with type 2 diabetes mellitus, over 18 years old and a baseline systolic blood pressure between 140-160 mm Hg. Intervention: One group receives treatment with a breathing device (Resperate©) and the other group receives treatment with a "control" breathing device. The latter device does not try to alter the breathing pattern. Main study parameters/endpoints: The effect of the breathing device on SBP is the main study parameter. Secondary endpoints include diastolic blood pressure (DBP) and quality of life.

Eligible patients will be randomized in a 1.1 ratio to receive Travoprost 0.004%/timolol 0.5% once daily or Latanoprost 0.005%/Timolol 0.5% once a day for 8 Weeks. The study treatments will be compared for mean diurnal intraocular pressure (IOP) change from baseline at Week 8. Safety parameters measured at 4 study visits: ocular signs, visual acuity, dilated fundus, cardiovascular parameters (blood pressure and pulse), and adverse events.

In this research study, the investigators are interested in learning how extracts from grape seeds can help those individuals with high blood pressure. The investigators also hope to learn how grape seed extract effects your blood and cell functions. The grape seed extract the investigators will use in the study will be provided either in a beverage or a capsule form and is currently available on the market. This study is also using a placebo; therefore the treatment subjects receive may or may not contain the grape seed extract. The purpose of this study is to determine if the grape seed extract (GSE) will lower blood pressure in people with slightly high blood pressure (Pre-Hypertension).

This study assessed the efficacy and safety of combination therapy of Aliskiren/Amlodipine or Aliskiren/Amlodipine/Hydrochlorothiazide in patients with stage II Hypertension.

The primary object of this study is to evaluate the efficacy and safety of 6 weeks of nebivolol monotherapy compared with placebo in patients with systolic stage 2 hypertension.

Insufficient blood pressure control is a frequent problem despite the existence of effective treatment. One of the causes is insufficient self-monitoring and a lack of adherence to therapy. Blood pressure self-measurement at home (Home Blood Pressure Measurement, HBPM) has positive effects on treatment adherence and is helpful in achieving the target blood pressure. Only a few studies have investigated whether the adherence for HBPM can be improved through simple measures and better blood pressure monitoring can be achieved. Objective Improvement of self-monitoring by means of blood pressure self-measurement and improved blood pressure control by using a new colour-coded blood pressure diary

The purpose of this study is to evaluate the long-term safety of SPARC0913. A multicenter, open label, non-randomized, uncontrolled, single group assignment, safety study of subjects with primary open angle glaucoma or ocular hypertension is planned. Subjects will receive study medication for a period of 24-weeks.

The purpose of this study is to evaluate the safety and preliminary efficacy of two formulations of the Latanoprost-PPDS in subjects with ocular hypertension or open-angle glaucoma.

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.
