What is the purpose of this trial?

This trial explores how the body absorbs and processes a combination of two medications, Extended Release Torsemide and Spironolactone, when taken together over time. Researchers aim to understand the consistency of these effects in healthy adults. Healthy non-smokers without significant health issues may find this trial suitable. As a Phase 3 trial, it represents the final step before FDA approval, offering participants the chance to contribute to a treatment nearing potential public availability.

Do I need to stop taking my current medications to join the trial?

Yes, you need to stop taking any medications, including over-the-counter and herbal products, for 14 days before joining the study.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Previous studies have examined how the combination of Extended Release Torsemide and Spironolactone works in the body. This research shows that the treatment is generally well-tolerated, with most people not experiencing serious problems. No major safety concerns have been reported with the combination.

Torsemide and Spironolactone are medicines already used for other health issues, and their safety is well established. Some people might experience mild side effects like dizziness or fatigue, which are common for these types of medications.

This trial is in an advanced phase, indicating strong evidence that the treatment is safe. However, as with any medication, consulting a healthcare provider is important to determine if it's a suitable option. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the extended release (ER) fixed dose combination of Torsemide and Spironolactone because it simplifies dosing by combining two effective diuretics into one tablet. This combination enhances convenience by reducing the number of pills a patient needs to take daily, potentially improving adherence to treatment. Additionally, the extended-release formulation of Torsemide may provide a more consistent and sustained effect, which can better manage symptoms compared to traditional immediate-release forms. Unlike standard treatments that require separate dosing, this innovative approach aims to streamline management for conditions like heart failure, where diuretics play a crucial role.

What evidence suggests that this trial's treatments could be effective?

This trial will compare the bioavailability of two treatment arms: one with an Extended Release Torsemide and Spironolactone Fixed Dose Combination (FDC) and another with separate Torsemide and Spironolactone tablets. Research has shown that taking Extended Release Torsemide with Spironolactone might enhance the body's absorption of these medications. Torsemide, a diuretic, helps the body eliminate excess fluid, while Spironolactone reduces fluid by blocking certain hormones. Studies suggest that when taken together, these medicines may be absorbed more consistently and work more effectively. This combination could improve treatment for conditions like heart failure or high blood pressure, where managing fluid levels is crucial. Early research indicates a steady and reliable absorption pattern when these drugs are used together. ^{1 2 3 6 7}
