Potassium citrate may be used to control kidney stones due to either uric acid or cystine. Potassium citrate is a white, slightly hygroscopic crystalline powder. Potassium citrate is odorless with a saline taste.
Potassium citrate is rapidly absorbed when given by mouth and is excreted in the urine as the carbonate. Potassium citrate is, therefore, effective in reducing the pain and frequency of micturition when these are caused by highly acidic urine. Potassium citrate is used for this purpose in dogs and cats, but is chiefly employed as a non-irritating diuretic. Potassium citrate is an effective way to treat/manage gout and arrhythmia, if the patient is hypokalemic. In common with other substances that render the urine alkaline, Potassium citrate may be used to reduce the danger of crystalluria during sulfonamide therapy. Potassium citrate is widely used to treat urinary calculi (kidney stones), and is often used by patients with cystinuria. A study of 500 patients with recurrent stones found that Potassium citrate reduced the frequency of stones from 2 per year to a half per year. Potassium citrate is also used in many soft drinks as a buffering agent.
