Description

A key intermediate in metabolism. It is an acid compound found in citrus fruits. The salts of citric acid (citrates) can be used as anticoagulants due to their calcium chelating ability.

Toxicity

ORAL (LD50): Acute: 5040 mg/kg [Mouse]. 3000 mg/kg [Rat].

Active Ingredient/Synonyms

2-Hydroxytricarballylic acid | 3-Carboxy-3-hydroxypentane-1,5-dioic acid | Citric Acid, Anhydrous | Citronensäure | Citric Acid |

Description

Sodium citrate is the sodium salt of citric acid. It is white, crystalline powder or white, granular crystals, slightly deliquescent in moist air, freely soluble in water, practically insoluble in alcohol. Like citric acid, it has a sour taste. From the medical point of view, it is used as alkalinizing agent. It works by neutralizing excess acid in the blood and urine. It has been indicated for the treatment of metabolic acidosis.

Indication

Used as an anticoagulant during plasmophoresis as well as a neutralizing agent in the treatment of upset stomach and acidic urine [FDA Label] [L788] [L789].

Mechanism of Action

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 [A19410] [A19411]. 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 [A19410]. 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 [L790]. It also acts as a diuretic and increases the urinary excretion of calcium.

Pharmacokinetics

Absorption
Tmax of 98-130min [A19414].
Distribution
19-39L [A19414].
Metabolism
Citrate is metabolized to bicarbonate in the liver and plays a role as an intermediate in the citric acid cycle [A19419] [L795].
Elimination

Clearance

Total clearance of 313-1107mL/min [A19414].

Toxicity

Overdose toxicity is mainly due to alkalosis as well as tetany or depressed heart function due to lack of free calcium [L790].

Active Ingredient/Synonyms

Sodium citrate anhydrous | Sodium citrate, anhydrous | trisodium citrate anhydrous | Trisodium citrate, anhydrous | Sodium Citrate |
