Sodium carbonate

Identification

Generic Name
Sodium carbonate
DrugBank Accession Number
DB09460
Background

Sodium Carbonate is the disodium salt of carbonic acid with alkalinizing property. When dissolved in water, sodium carbonate forms carbonic acid and sodium hydroxide. As a strong base, sodium hydroxide neutralizes gastric acid thereby acting as an antacid.

Pharmacodynamics

Alkalizing buffering action: Sodium bicarbonate is an alkalinizing agent that dissociates to provide bicarbonate ion. Bicarbonate in excess of that needed to buffer hydrogen ions causes systemic alkalinization and, when excreted, urine alkalinization as well. Oral antacid action: Taken orally, sodium bicarbonate neutralizes stomach acid by the above mechanism.

Mechanism of action

Carbon dioxide from the tissues diffuses rapidly into red blood cells, where it is hydrated with water to form carbonic acid. This reaction is accelerated by carbonic anhydrase, an enzyme present in high concentrations in red blood cells. The carbonic acid formed dissociates into bicarbonate and hydrogen ions. Most of the bicarbonate ions diffuse into the plasma. Since the ratio of H2CO3 to dissolved CO2 is constant at equilibrium, pH may be expressed in terms of bicarbonate ion concentration and partial pressure of CO2 by means of the Henderson-Hasselbach equation: pH = pk + log [HCO3-]/aPCO2

Absorption

The uptake of sodium, via exposure to sodium carbonate, is much less than the uptake of sodium via food. Therefore, sodium carbonate is not expected to be systemically available in the body. Furthermore, an oral uptake of sodium carbonate will result in a neutralization in the stomach due to the gastric acid.

Volume of distribution

Distribution occurs naturally and is confined to the systemic circulation.

Protein binding

Not Available

Metabolism

None.

Route of elimination

Filtered and reabsorbed by the kidney; less than 1% of filtered bicarbonate is excreted.
