The Impact of TORasemide oN hemodynAmic & Neurohormonal Stress, & carDiac

Status Recruiting

Clinical Trial Summary

The aim of the study is to compare the effects of torasemide and furosemide on clinical and biochemical parameters of hemodynamic and neurohormonal compensation and myocardial remodeling in patients with chronic heart failure with indications for use of loop diuretics.

The study protocol 100 patients with heart failure NYHA (New York Heart Association) II-IV (stable or exacerbation aligned cardiopulmonary at the time of enrollment, with a fixed-dose loop diuretics]) treated with optimal medical therapy as clinically indicated for use loop diuretics. Patients will be randomized to treatment with furosemide and torasemide (randomization 1 : 1). After randomization, furosemide will continue in its current fixed-dose or will be replaced by equipotential dose of torasemide (4:1). The minimal follow-up of patients in the study will be at least six months.

Clinical Trial Description

According to current guidelines, angiotensin converting enzyme inhibitors and beta-adrenolytics are the first-line treatment agents in patients with heart failure. In case of fluid retention, diuretics, as a part of symptomatic treatment, should be administered. In practice, the most common diuretic used in patients with heart failure is loop diuretic - furosemide. What is important, furosemide has no effect on patients' outcomes. Some studies showed unfavourable influence of this drug on rennin-angiotensin-aldosterone system.

Alternative loop diuretic, which may be administered in patients with heart failure is torasemide. Its longer elimination half-life time, similar diuretic effects, lower influence on electrolyte disorders and additional pleiotropic effects could make torasemide more beneficial than furosemide.

Accordingly, only direct comparison of furosemide and torasemide could present similarities and differences of these two agents.

The hypothesis of this study is that torasemide may present more favourable effects on some clinical parameters in patients with heart failure, than furosemide (e.g. clinical symptoms, biochemical parameters, activity of rennin-angiotensin-aldosterone system, side effects). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
