Active clinical trials for "Hypertension"

Evaluation of the ocular hypotensive efficacy and safety of Netarsudil (AR-13324) Ophthalmic Solution compared to Timolol Maleate Ophthalmic Solution

This is an open-label, placebo run-in study to investigate the genetic and biomedical predictors of blood pressure response to bisoprolol. After informed consent is obtained, subjects will be withdrawn from previous antihypertensive therapy and given placebo for at least 2 weeks. Compliance will be assessed using pill counting, and any subject will a compliance less than 80% during the placebo run-in period will be excluded from the study. Bisoprolol 2.5 mg will be given once daily for 6 weeks. At baseline and after 6 weeks on bisoprolol 2.5 mg the clinic sitting blood pressure, 24-hour ambulatory blood pressure (if the patient is willing to do this), clinical characteristics and biochemical profile will be measured. Central aortic blood pressure will be measured with the A-PULSE device at baseline and after 6 weeks treatment. After completing 6 weeks treatment with bisoprolol 2.5 mg daily, the patient will continue treatment with bisoprolol for a total of 24 weeks unless there is any adverse event that requires discontinuation of bisoprolol.

24-week study to evaluate the efficacy and safety of macitentan for the treatment of portopulmonary hypertension.

This is a phase IV prospective trial to collect and analyze information about the maternal pharmacokinetics of amlodipine besylate at the time of delivery and during postpartum lactation. The study will also evaluate amlodipine concentrations in the infants of breastfeeding mothers who are taking amlodipine besylate for treatment chronic hypertension.

"Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe form of pulmonary hypertension characterized by obstruction of the pulmonary vasculature by residual organized thrombi, leading to increased pulmonary vascular resistance (PVR), progressive pulmonary hypertension, and right failure. In patients deemed operable, pulmonary endarterectomy (PEA) is the gold standard treatment and is the only potentially curative treatment. However, some patients are ineligible for surgery owing to occlusion of distal vessels. The best treatment option for these non-operable CTEPH patients is not yet established.

Background: Calcineurin inhibitors (CNIs) are the most commonly used immunosuppressive drugs to prevent rejection after kidney transplantation. However, the efficacy of preventing rejection comes at the cost of important side-effects. Among the most common side-effects is hypertension. Hypertension after kidney transplantation is clinically relevant, because it increases the risk of cardiovascular disease and is associated with increased graft loss and recipient mortality. The mechanism of CNI-induced hypertension is incompletely understood and, therefore, the treatment is currently empiric. These and other investigators recently showed that CNIs cause salt-sensitive hypertension by activating a sodium transporter in the kidney, namely the thiazide-sensitive sodium chloride cotransporter. Hypothesis: The investigators hypothesize that thiazide diuretics are non-inferior to calcium channel blockers (CCBs) (currently usually the treatment of choice) for the treatment of CNI-induced hypertension. Objective: To compare the blood pressure response to thiazide diuretics and CCBs in patients with CNI-induced hypertension. Study design: Single-center, randomized cross-over trial. Study population: Kidney transplant recipients with a good functioning allograft (eGFR > 30 ml/min) who are hypertensive (daytime systolic blood pressure > 140 mm Hg) and who do not have proteinuria (< 1 g/day). Intervention: Patients will be randomized to receive chlorthalidone (12.5 mg once daily, if needed titrated to 25 mg once daily) or amlodipine (5 mg once daily, if needed titrated to 10 mg once daily). Main study parameters/endpoints: 24-hour blood pressure recording. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Both drugs have long been registered for the treatment of hypertension. The side-effect profile of both drugs is considered to be equal. The burden of the study for the patients are blood pressure measurements using 30-minute automated blood pressure measurement and 24-hour ambulatory blood pressure measurement.

This study will evaluate the intraocular pressure (IOP)-lowering effect and safety of Bimatoprost SR compared with selective laser trabeculoplasty in participants with open-angle glaucoma or ocular hypertension who are not adequately managed with topical IOP-lowering medication for reasons other than medication efficacy (e.g., due to intolerance or nonadherence).

This study is a multi-center, open label, dose titration, exploratory study to evaluate efficacy and safety of CS-3150 in Japanese hypertensive patients with moderate renal impairment. Primary endpoint is change from baseline in sitting systolic and diastolic blood pressure.

The primary objective of this study is to evaluate the effect of selonsertib (GS-4997) on pulmonary vascular resistance (PVR), as measured by right heart catheterization (RHC) in adults with pulmonary arterial hypertension (PAH). The study will consist of a 24-week placebo-controlled treatment period and a long-term selonsertib treatment period. Participants completing the 24-week placebo-controlled period will be eligible to receive active treatment with selonsertib in the long-term treatment period.

The purpose of this study is to investigate which combination therapy is more effective for improving the blood pressure (BP) and AM central SBP in hypertensive patients:Angiotensin II receptor blocker (ARB) plus calcium channel blocker (CCB) or ARB plus diuretics
