4.3 Drug Indication

Injection, USP 40 mEq is indicated as a source of sodium, for addition to large volume intravenous fluids to prevent or correct hyponatremia in patients with restricted or no oral intake. It is also useful as an additive for preparing specific intravenous fluid formulas when the needs of the patient cannot be met by standard electrolyte or nutrient solutions. Sodium acetate and other bicarbonate precursors are alkalinising agents, and can be used to correct metabolic acidosis, or for alkalinisation of the urine.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Sodium is the principal cation of extracellular fluid. It comprises more than 90% of total cations at its normal plasma concentration of approximately 140 mEq/liter. The sodium ion exerts a primary role in controlling total body water and its distribution. Acetate ions acts as hydrogen ion acceptor which is alternative to bicarbonate.


5.2 FDA Pharmacological Classification
5.2.1 Pharmacological Classes
Inhibition Large Intestine Fluid/Electrolyte Absorption [PE]; Osmotic Activity [MoA]; Osmotic Laxative [EPC]; Increased Large Intestinal Motility [PE]
5.3 ATC Code

B - Blood and blood forming organs

B05 - Blood substitutes and perfusion solutions

B05X - I.v. solution additives

B05XA - Electrolyte solutions

B05XA08 - Sodium acetate


5.4 Absorption, Distribution and Excretion

Absorption

It is readily available in the circulation after IV administration.


Route of Elimination

Both the sodium and bicarbonate ions are excreted mainly in the urine. Some sodium is excreted in the feces, and small amounts may also be excreted in saliva, sweat, bile and pancreatic secretions.


5.5 Metabolism/Metabolites

In liver, sodium acetate is being metabolized into bicarbonate. To form bicarbonate, acetate is slowly hydrolyzed to carbon dioxide and water, which are then converted to bicarbonate by the addition of a hydrogen ion.


THE ACETATE ION IS RAPIDLY & COMPLETELY METABOLIZED BY BODY, & CONSEQUENTLY ADMIN OF SODIUM ACETATE IS EVENTUALLY EQUIVALENT TO GIVING SODIUM BICARBONATE. /SODIUM ACETATE TRIHYDRATE, USP/

5.6 Mechanism of Action

It works as a source of sodium ions especially in cases of hyponatremic patients. Sodium has a primary role in regulating extracellular fluid volume. It controls water distribution, fluid and electrolyte balance and the osmotic pressure of body fluids. Sodium is also involved in nerve conduction, muscle contraction, acid-base balance and cell nutrient uptake.
