First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares a cheap medicine, sodium bicarbonate, to the standard prescription potassium citrate for preventing kidney stones. About 30 adults with a history of stones and low urinary citrate will take one of the two medicines. The goal is to see if sodium bicarbonate can raise urine citrate levels just as well, which could make prevention more affordable and easier to stick with.
