Potassium citrate is rapidly absorbed when given by mouth and is excreted in the urine. Since it is an alkaline salt it is effective in reducing the pain and frequency of urination when these are caused by highly acidic urine.[medical citation needed] It is used for this purpose in dogs and cats, but is chiefly employed as a non-irritating diuretic.
It is widely used to treat urinary calculi (kidney stones) and is often used by patients with cystinuria.[medical citation needed] A study of 500 patients with recurrent stones found that it reduced the frequency of stones from 2 per year to a half per year.
Potassium citrate is usually administered by mouth in dilute aqueous solution. This is because of its somewhat caustic effect on the stomach lining, and the potential for other mild health hazards.
In states where non-prescription potassium citrate is legal, the maximum allowable over-the-counter (OTC) dose for elemental potassium is regulated by the FDA to be no more than 100 mg (approximately 3% of the daily allowance). Pure potassium citrate contains 38.28% potassium.
