Pharmacodynamics · 1 item

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 · 1 item

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.

Metabolism/MetabolitesPotassium Citrate is absorbed and the citrate is metabolised to bicarbonate.
