NCT ID NCT07460882
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test whether a low-sodium salt substitute, which contains potassium chloride, is safe for adults with high blood pressure who are on medication. About 607 participants in Bangladesh will replace regular salt with the substitute for a period. Researchers will monitor potassium levels in the blood to see if dangerous increases occur, and also check if it helps correct low potassium levels.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
low-sodium salt substitute (potassium chloride)
What this could lead to
If it works, this could show that low-sodium salt substitutes are safe for widespread use in people with high blood pressure, helping control blood pressure without major risks.
What could go wrong
This is an early pre-post study, not a randomized trial, so results may not be conclusive. There is a risk of high potassium levels (hyperkalemia), especially in people on certain blood pressure medications.
