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.

Brand Names
Cytra-K, Urocit-K
Generic Name
Potassium citrate
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.

DrugInteraction
AbacavirPotassium citrate may increase the excretion rate of Abacavir which could result in a lower serum level and potentially a reduction in efficacy.
AbciximabThe risk or severity of bleeding can be increased when Abciximab is combined with Potassium citrate.
AcebutololPotassium citrate may increase the hyperkalemic activities of Acebutolol.
AceclofenacThe risk or severity of bleeding and hemorrhage can be increased when Aceclofenac is combined with Potassium citrate.
AcemetacinThe therapeutic efficacy of Potassium citrate can be decreased when used in combination with Acemetacin.
AcenocoumarolThe risk or severity of bleeding can be increased when Acenocoumarol is combined with Potassium citrate.
AcetaminophenPotassium citrate may increase the excretion rate of Acetaminophen which could result in a lower serum level and potentially a reduction in efficacy.
Acetylsalicylic acidAcetylsalicylic acid may increase the anticoagulant activities of Potassium citrate.
AclidiniumPotassium citrate may increase the excretion rate of Aclidinium which could result in a lower serum level and potentially a reduction in efficacy.
AcrivastinePotassium citrate may increase the excretion rate of Acrivastine which could result in a lower serum level and potentially a reduction in efficacy.
