Active clinical trials for "Hypertension"

This study assesses the safety and efficacy of bardoxolone methyl relative to placebo in patients with pulmonary hypertension to determine the recommended dose range, evaluate the change from baseline in 6-minute walk distance (6MWD) and determine the effect of Bardoxolone methyl in pulmonary hypertension associated with connective tissue disease, interstitial lung disease, and idiopathic etiologies, including subsets of patients with WHO Group III or WHO Group V PH following 16 weeks of study participation.

This will be an open-label, randomized, single dose, two-way crossover study. Each subject will participate in both treatment periods and will receive single oral doses of candesartan cilexetil (GW615775) and reference candesartan cilexetil (ATACAND™); the treatment periods will be separated by a washout period of at least 7 days and no greater than 14 days. This study aims to determine the relative bioavailability of an 8mg test formulation tablet of candesartan cilexetil (GW615775) compared to an 8mg reference tablet of candesartan cilexetil in healthy adult subjects. ATACAND is a registered trademark of the AstraZeneca group of companies.

BAY63-2521 Riociguat leads to the relaxation of smooth muscle cells in pulmonary arteria and may also inhibit abnormal remodeling of lung blood vessels. In patients with pulmonary arterial hypertension Riociguat showed to reduce the pulmonary blood pressure and improved the right heart function without unacceptable side effects. Here dose of Riociguat will be adjusted over 8 weeks then a Maintenance Phase of 16 weeks follows. Patients with Pulmonary Arterial Hypertension treated with stable doses of Phosphodiesterase Type-5 Inhibitors (Eg Sildenafil, Tadalafil) not appropriately responding to therapy will be included. Based on previous evidence and on the different modes of action an improvement of exercise capacity, heart function and quality of life may be expected if PDE5i treatment is transitioned to riociguat. Where Riociguat is pending market approval or reimbursement once the treatment phase is completed drug can be made available for another 18 months (Extended Drug Supply Phase - EDSP) under study conditions. Patients may also transition at the end of the maintenance period or any time during the EDSP to any program that is intended to provide riociguat until drug approval/reimbursement, e.g. a long-term extension study, compassionate use or named patient program. Study termination is also possible at any time.

The main purpose of this study is to evaluate the safety and effectiveness of the study drug known as LY2623091 in participants with high blood pressure.

Increased intraocular pressure (IOP) has been identified as the most important risk factor for the development and the progression of glaucoma. Data from large interventional studies have shown that a decrease of IOP is associated with a reduced risk of progression of the disease. This underlines the importance of a potent and save IOP lowering therapy. The introduction of preservative free tafluprost offers a new treatment possibility using a potent topical prostaglandin analogue without the disadvantages of a co-administered preservative. The current study seeks to investigate the effect of an 8 week therapy with preservative free tafluprost on intraocular pressure in patients with ocular hypertension or primary open angle glaucoma having an IOP of 30 mmHg or more.

This research proposal is submitted to fulfill the requirement of the PHD degree of Community Medicine Saudi Board at the Joint Program of Family and Community Medicine in Jeddah, Saudi Arabia. Background: Cupping is an ancient treatment remedy that has been used for many centuries in many parts of the world. In the Middle East, Wet cupping "Hijama" is still a popular treatment because of its religious background. Despite of that, it still has little scientific evidence that proves its efficacy. Many hijama healers claim that they have observed dramatic improvement in Blood pressure control of hypertension patients. Not many studies support that. This study should help to prove or disprove this hypothesis. Objectives: To determine the efficacy of wet cupping on blood pressure among high blood pressure patients. To assess the incidence of wet cupping side effects in the intervention group. Methods: The study design is a randomised controlled trial. There will be an intervention group of high blood pressure patients who will perform hijama in addition to their usual management, and a control group of high blood pressure patients who will receive their usual anti-hypertension management only. There will be 8 weeks follow up period. After that, data entry, analysis and interpretation will take place. Hypothesis: Wet cupping has an effect on blood pressure in adult hypertension patients

Assessing the safety and effectiveness of a 11-βhydroxysteroid dehydrogenase type 1 inhibitor (AZD4017), in a placebo controlled trial, in acute idiopathic intracranial hypertension (IIH) IIH is a condition of young, overweight women with characteristic raised intracranial pressure (pressure around the brain) leading to papilloedema (swelling of the nerve supplying the eye), visual loss and headaches. Medical literature (Cochrane review) demonstrates there is little evidence for the treatments used for IIH. Weight control appears the most effective method of improving symptoms but weight loss is difficult to maintain. 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) is an enzyme which regulates local steroid levels and our previous research suggests it may influence the production of brain fluid(cerebrospinal fluid or CSF). 11β-HSD1 levels fall with weight loss and this is associated with with decreased intracranial pressure. Our primary outcome is to determine whether AZD4017, an inhibitor of 11β-HSD1, will reduce the pressure in the brain and as a consequence improve IIH. Patients are eligible to enter the study if they are between 18-55 years old with acute (<6 months) IIH, signs of active disease (papilloedema and raised CSF pressure (>25 cmH20)), no other major illnesses and have no plans for pregnancy during the study period. This is an MRC funded single centre, phase II, double-blinded, randomised control drug trial. It will be conducted at the University Hospital Birmingham and the University of Birmingham will act as Sponsor. Eligible participants will be randomly assigned to AZD4017 or a placebo ('dummy' with no active drug) for 3 months with a follow up a month later. Investigations during the study will include bloods, urine samples, pregnancy tests, lumbar punctures, DXA scans and small fat/skin biopsies. Participants will benefit from increased monitoring and a potential improvement in their condition. We hypothesise that specific inhibition of 11β-HSD1 will decrease intracranial pressure and consequently treat patients with IIH, thus opening a new and entirely novel therapeutic avenue.

To assess the effectiveness of reporting statin adherence patterns to a Medication Adherence Partner (MAP) in improving the outcome of statin adherence versus usual care as measured by an electronic pill bottle. Hypothesis: Subjects with a MAP receiving daily adherence feedback will have the highest statin adherence of any arm, as measured by pill bottle data.

The prevalence and incidence of cardiovascular disease (such as Hypertension) increases exponentially with age (McDermott, 2007;) These diseases account for 30% of the global mortality (WHO, 2011). Vitamin D (VD) insufficiency affects as many as half of otherwise healthy adults in developed countries (Holick, 2007). VD is implicated in the control of blood pressure (BP) through inhibition of the renin-angiotensin system (Yamshchikov, 2009), although the role of VD supplementation for prevention and treatment of the HTA is controversial.The purpose of this study was to investigate if VD supplement in elderly people reduces the levels of BP.

The primary objective of this study is to assess the safety and tolerance of changing patients currently on bosentan to ambrisentan for the treatment of pulmonary arterial hypertension.
