Active clinical trials for "Hypertension"

In Colombia, ischemic heart disease and stroke are one of the most important causes of death in 45 years old people. Care of cases of disease represents high costs for the health system in particular and society in general, due to the loss of productive years life and costs for the care of the aftermath. Hypertension (HT) is one of the preventable risk factors for major cerebrovascular disorders. The pathophysiology of Essential hypertension is complex and depends of interaction of genetic and environmental factors. Among the determining elements are the increase in the activity of the sympathetic nervous system, the vasoconstricting and overproduction of hormones associated with sodium retention, disruption in renin secretion with increased production of aldosterone and angiotensin II, the deregulation of the kinins system, the increase in peripheral vascular resistance and activity of Growth factors in atherogenesis and vascular endothelial dysfunction, increased cardiac output, diabetes mellitus, obesity, and lower production of vasodilators such as brain natriuretic peptide (BNP), the prostacyclins and nitric oxide (NO), among others. Cocoa is a food rich in flavonoids, which stimulate the enzyme activity of endothelial nitric oxide synthase (e-NOS), responsible of the production of NO in vascular smooth muscle. The flavonoids modulate the synthesis of inflammatory substances that are derived from endothelial cells and the immune system. In a recent study found that with a few grams of cocoa achieves a significant reduction in blood pressure, so the investigators propose a controlled clinical trial to assess the effect of different doses of cocoa on blood pressure and endothelial inflammation in men with essential hypertension, stage I-II without target organ damage, in addition to pharmacologic monotherapy defined for the management of their disease. The investigators hope to determine an optimal dose of cocoa, with long-term effects, by their high content of flavonoids, improves cardiovascular and endothelial parameters with the advantage that it is an economical and easy introduction into the patient's habits.

The primary objective is to investigate the safety of Caduet (2.5 mg/5 mg, 2.5 mg/10 mg, 5 mg/5 mg or 5 mg/10 mg as dose of Amlodipine/Atorvastatin) during 52 weeks treatment period in Japanese patients with both of hypertension and hypercholesterolemia, or with both angina pectoris and hypercholesterolemia.

The purpose of this study is to evaluate the long-term safety and tolerability of the combination of aliskiren and amlodipine given to patients with essential hypertension. This study is being conducted to support registration of the fixed combination of aliskiren/amlodipine in the treatment for hypertension in Japan.

This is a randomized, double-blind, placebo-controlled study. The hypothesis for this study is that single oral doses of MK-8266 selected for this study are sufficiently safe and well tolerated by elderly male and elderly female participants with hypertension to permit continued clinical investigation.

This study evaluated the ocular surface tolerability of the prostaglandin analogues bimatoprost ophthalmic solution 0.01% (Lumigan® 0.01%), travoprost ophthalmic solution 0.004% (Travatan Z®) and latanoprost ophthalmic solution 0.005% (Xalatan®) in patients previously treated with Xalatan® who have open-angle glaucoma or ocular hypertension.

The purpose of this trial is to evaluate if an objective clinical decision of anti-hypertensive therapy can be made using an N-of-1 (single patient) trial design.

Pulmonary Arterial Hypertension (PAH) is a severe progressive disease with a high mortality. Although several drugs are available for the treatment of PAH none offer a cure, therefore there is still a high medical need for new treatments. Soluble guanylate cyclase (sGC) is one of the chemicals involved in the pathways controlling vascular tone, which is impaired in patients with PAH. This causes constriction and thickening of the blood vessels wall in the lungs and increase of blood pressure in the lungs. This can lead to the very debilitating symptoms of PAH such as tiredness, shortness of breath on exertion, collapse and often the inability of the patient to perform their daily life activities. Inhalation of Nitric Oxide, which activates sGC is used to treat PAH, but its effect wears off as soon as inhalation stops. Direct stimulation of sGC using this new compound Riociguat may be a new approach for the treatment of PAH. The phosphodiesterase 5 (PDE5)-inhibitor Sildenafil is one of licensed treatments for PAH. The Patent Plus is a double-blind, placebo-controlled safety study, designed to investigate the effect of Riociguat on blood pressure in patients with PAH when given in combination with Sildenafil.

Subcutaneous treprostinil (Remodulin) is effective therapy for pulmonary arterial hypertension, a life threatening disease of the lung blood vessels. Unfortunately, treprostinil is irritating to the skin and many patients experience intense pain at the infusion site for the first 7-10 days after placing a new subcutaneous infusion site. Qutenza is an FDA approved formulation of 8% capsaicin that is approved for the treatment of post-herpetic neuralgia, a painful skin condition. The investigators hypothesize that pretreatment of an area of skin with Qutenza would decrease the pain associated with a new treprostinil infusion site. The investigators hope that Qutenza will decrease both the intensity of the pain and the duration of the pain after patients place a new treprostinil infusion site. In this initial study, the investigators will provide Qutenza in open-label, unblinded fashion and ask patients to rate their pain using a diary tool with which they are already comfortable.

To investigate the safety and efficacy of DE-112 in lowering intraocular pressure in subjects with primary open-angle glaucoma or ocular hypertension.

A Phase 2 open label, dose escalation study to find the minimally and maximum effective dose (dose beyond which no further effect on PVR is seen) of inhaled nitric oxide generated by the GeNOsyl® System compared to placebo.
