One pill to stop a second stroke? triple combo tested
NCT ID NCT02699645
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This large, completed phase 3 trial tested whether a single pill containing three low-dose blood pressure medicines (telmisartan, amlodipine, and indapamide) could prevent another stroke in 1,671 people who had previously had a bleeding stroke (intracerebral haemorrhage) and had high blood pressure. Participants took the triple pill or a placebo daily for about 6 years, alongside their usual care. The study aimed to see if this approach reduces the risk of recurrent stroke.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- telmisartan, amlodipine, and indapamide (Triple Pill)
- What this could lead to
- If it works, this could provide a simple, once-daily pill to help prevent recurrent strokes in people who have had a bleeding stroke.
- What could go wrong
- This trial is completed, but results may not apply to all patients. The triple pill may cause side effects like dizziness or low blood pressure, and it may not reduce stroke risk as hoped.
