Glaucoma supplement trial fizzles: MEMOPTIC study halted early
NCT ID NCT04499157
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a daily tablet called MEMOPTIC (containing citicoline, magnesium, and Ginkgo biloba) could help preserve vision in people with open-angle glaucoma when added to their usual eye-pressure-lowering treatments. The trial planned to follow 15 patients for two years, but it was terminated early. Because of the small size and early stop, no firm conclusions can be drawn about whether MEMOPTIC helps protect vision.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MEMOPTIC (a tablet combining citicoline, magnesium, and Ginkgo biloba)
- What this could lead to
- If it worked, MEMOPTIC might help preserve vision in glaucoma patients when added to standard pressure-lowering treatments.
- What could go wrong
- The trial was terminated early and included only 15 people, so results are very limited. It is unclear if the supplement provides any real benefit over standard care.
