Citrate chelates free calcium ions preventing them from forming a complex with tissue factor and coagulation factor VIIa to promote the activation of coagulation factor X . This inhibits the extrinsic initiation of the coagulation cascade. Citrate may also exert an anticoagulant effect via a so far unknown mechanism as restoration of calcium concentration does not fully reverse the effect of citrate . Citrate is a weak base and so reacts with hydrochloric acid in the stomach to raise the pH. It it further metabolized to bicarbonate which then acts as a systemic alkalizing agent, raising the pH of the blood and urine . It also acts as a diuretic and increases the urinary excretion of calcium.
Used as an anticoagulant during plasmophoresis as well as a neutralizing agent in the treatment of upset stomach and acidic urine .
