Description

 

Potassium citrate is a potassium salt of citric acid. As a food additive, potassium citrate is used to regulate acidity. Medicinally, it may be used to control kidney stones derived from either uric acid or cystine. Potassium citrate is an effective way to treat gout and arrhythmia, if the patient is hypokalemic. In common with other substances that render the urine alkaline, it may be used to reduce the danger of crystalluria during sulfonamide therapy. It is widely used to treat urinary calculi (kidney stones), and is often used by patients with cystinuria.
