Could a heart drug ease pressure inside the eye?
NCT ID NCT07795762
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
This trial tests whether eplerenone, a drug already approved for other conditions, lowers eye pressure in healthy adults. Researchers will compare eplerenone with a placebo in a crossover design, where each participant takes both treatments at different times. Eye pressure is measured throughout, and blood pressure, kidney function, and potassium levels are monitored for safety. If eplerenone reduces eye pressure, it might offer a new approach to treating glaucoma.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Eplerenone, an oral medication approved for other conditions, taken as a 50 mg capsule once daily for one week.
- What this could lead to
- If eplerenone lowers eye pressure, it could point toward a new treatment for glaucoma, a disease where high eye pressure damages vision.
- What could go wrong
- This is a small, early-phase trial in healthy people, so results may not apply to glaucoma patients. Eplerenone can affect blood pressure, kidney function, and potassium levels, which the study monitors for safety.
