Active clinical trials for "Hypertension"

The majority of hypertensive patients require antihypertensive associations to control their blood pressure. Most of clinical trials don't compare different associations using Hydrochlorothiazide 25 mg as the standard initial therapy and compare the associations using doses that are not equivalent. This randomized trial where patients and investigators are blinded and compares the effectiveness two associations: Hydrochlorothiazide and Amiloride and Hydrochlorothiazide and Enalapril.

The purpose of the study is to compare the efficacy and safety of Timolol 0.5% solution to Brinzolamide 1% each given twice daily when added to Travoprost 0.004% given each evening.

The purpose of this study is to evaluate the efficacy of valsartan plus amlodipine in hypertensive patients not responding to treatment with ACE inhibitor plus calcium channel blocker

This study evaluated the efficacy and safety of amlodipine/benazepril compared with that of enalapril in the treatment of hypertension in African-American patients with type 2 diabetes.

The purpose of this study is to investigate the efficacy (blood pressure lowering effect) and safety of aliskiren given to hypertensive patients after a missed dose.

Evaluate the antihypertensive and neuroprotective effects of Hyzaar(R) in elderly subjects in comparison with Natrilix(TM).

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease that affects an individual's ability to breathe. Currently, no medications can reverse the damage to the lungs caused by IPF, but individuals are encouraged to engage in moderate exercise to strengthen lung function. This study will evaluate the effectiveness of sildenafil at improving exercise tolerance and breathing difficulties in individuals with IPF.

This is a randomized, double-blind, double-dummy, parallel group trial employing 15 cells of a 4x4 factorial design (no placebo)to compare the hypertensive effects in patients with Stage 1 and Stage 2 hypertension of carvedilol (20, 40 or 80 mg daily) alone, lisinopril (10, 20 or 40 mg daily) alone, and all combinations of the doses.

The sustained reduction in elevated blood pressure and lower incidence of adverse events of Lacidipine may provide additional benefits for hypertension patients than other CCBs (calcium channel blockers). This study is to compare the efficacy and safety of Lacidipine with Amlodipine, the most widely used CCB in Taiwan, in hypertensive patients.

This study is designed to provide long-term safety and efficacy data for the combination doses of VAH (VAL/ HCTZ) 40/6.25mg and 80/12.5mg in essential hypertensive patients. The 350 patients (approximately) who have successfully finished the core trial CVAH631B1303 and signed consent for the extension will be enrolled into this study.
