Potassium citrate
Identification
- Summary
Potassium citrate is an agent used to manage renal tubular acidosis, hypocitraturic calcium oxalate nephrolithiasis, and uric acid lithiasis with or without calcium stones.

- DrugBank Accession Number
- DB09125
- Background
Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid. It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.3% potassium by mass. In the monohydrate form it is highly hygroscopic and deliquescent. Potassium citrate is used to treat a kidney stone condition called renal tubular acidosis. Potassium Citrate is indicated also for the management of Hypocitraturic calcium oxalate nephrolithiasis.

- Pharmacodynamics
Potassium citrate induces changes in the urine which renders urine less susceptible to the formation of crystals and stones from salts e.g. calcium oxalate, calcium phosphate and uric acid. Increased citrate levels in the urine will make complexation with calcium which decrease the calcium ion activity and decrease the chance for the formation of calcium phosphate crystals. Citrate also inhibits the spontaneous nucleation of calcium oxalate and calcium phosphate.
- Mechanism of action
After oral administration of potassium citrate, its metabolism yields alkaline load. Potassium Citrate therapy appears to increase urinary citrate mainly by modifying the renal handling of citrate, rather than by increasing the filtered load of citrate. In addition to raising urinary pH and citrate, Potassium Citrate increases urinary potassium by approximately the amount contained in the medication. In some patients, Potassium Citrate causes a transient reduction in urinary calcium.
