Potassium citrate may offer antibiotic-free UTI relief
NCT ID NCT07202832
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether potassium citrate, a medication that makes urine less acidic, can relieve painful UTI symptoms in women aged 18-50. Fifty participants will take either potassium citrate or the antibiotic nitrofurantoin for 7 days. Researchers will compare symptom scores and urine culture results to see if the alkalinizer works as well as the antibiotic.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- potassium citrate
- What this could lead to
- If it works, this could offer a non-antibiotic option for relieving UTI symptoms, potentially reducing antibiotic use.
- What could go wrong
- This is a small, early-stage trial with only 50 participants. It may not show clear benefit, and potassium citrate might not clear the infection as well as antibiotics.
