4.2 Therapeutic Uses

Sodium chloride injections are used as a source of sodium chloride and water for hydration. Sodium chloride is used in the prevention or treatment of deficiencies of sodium and chloride ions and in the prevention of muscle cramps and heat prostration resulting from excessive perspiration during exposure to high temperature. Sodium chloride is also used to treat deficiencies of sodium and chloride caused by excessive diuresis or excessive salt restriction.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 2758


0.45% Sodium chloride injection is used principally as a hydrating solution and may be used to assess renal function status, since more water is provided than is required for excretion of salt. 0.45% Sodium chloride injection is also used in the management of hyperosmolar diabetes.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 2758


0.9% Sodium chloride injection is used for extracellular fluid replacement and in the management of metabolic alkalosis in the presence of fluid loss and mild sodium depletion. 0.9% Sodium chloride injection (normal saline) is also used as a priming fluid for hemodialysis procedures and to initiate and terminate blood transfusions.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 2758


Hypertonic (i.e., 3%, 5%) sodium chloride injection is used in the management of severe sodium chloride depletion when rapid electrolyte restoration is essential. Severe sodium chloride depletion may occur in the presence of heart failure or renal impairment, or during surgery or postoperatively. In these conditions, chloride loss often exceeds sodium loss. Hypertonic sodium chloride injections are also used in the management of hyponatremia and hypochloremia resulting from administration of sodium-free fluids during fluid and electrolyte therapy; in the management of extreme dilution of extracellular fluid following excessive water intake (e.g., that resulting from multiple enemas or perfusion of irrigating solutions into open venous sinuses during transurethral prostatic resections); and in the emergency treatment of severe sodium chloride depletion resulting from excess sweating, vomiting, diarrhea, and other conditions.

4.3 Drug Warning

Bacteriostatic sodium chloride injection containing benzyl alcohol as a preservative (antimicrobial agent) should not be used for diluting or reconstituting drugs for administration in neonates nor should it be used to flush intravascular catheters in neonates. Several deaths have been reported in neonates weighing less than 2.5 kg in whom bacteriostatic sodium chloride for injection containing 0.9% benzyl alcohol was used for flushing IV catheters; some of these neonates received additional benzyl alcohol when bacteriostatic sodium chloride injection was used to dilute or reconstitute drugs. The deaths were usually preceded by a syndrome that included metabolic acidosis, CNS depression, respiratory distress progressing to gasping respiration, hypotension, renal failure, and, occasionally, seizures and intracranial hemorrhage. High concentrations of benzyl alcohol, benzoic acid, and hippuric acid (a metabolite) were present in blood and urine in these neonates. Benzyl alcohol toxicity apparently was caused by administration of relatively large daily doses (99-404 mg/kg daily) of the preservative in proportion to the neonate's weight. Although these neonates had biochemical evidence of benzyl alcohol toxicity, they also had serious underlying conditions.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 2759


Sodium chloride is contraindicated in patients with conditions in which administration of sodium and chloride is detrimental. Sodium chloride 3 and 5% injections are also contraindicated in the presence of increased, normal, or only slightly decreased serum electrolyte concentrations.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 2759


Sodium chloride should be used with extreme caution, if at all, in patients with congestive heart failure or other edematous or sodium-retaining conditions, in patients with severe renal insufficiency, in patients with liver cirrhosis, and in patients receiving corticosteroids or corticotropin; particular caution is necessary in geriatric or postoperative patients. IV administration of sodium chloride may cause fluid and/or solute overload resulting in dilution of serum electrolytes, overhydration, congestive conditions, or pulmonary edema. The risk of dilutional conditions is inversely proportional to the electrolyte concentration administered, and the risk of solute overload and resultant congestive conditions with peripheral and/or pulmonary edema is directly proportional to the electrolyte concentration administered. The manufacturers warn that excessive IV administration of sodium chloride may result in hypokalemia.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 2759


Changes in fluid balance, electrolyte concentrations, and acid-base balance should be evaluated clinically and via periodic laboratory determinations during prolonged therapy with sodium chloride and in patients whose condition warrants such evaluation. Substantial changes may require additional electrolyte supplements or other appropriate therapy. Additional electrolyte supplementation may also be required in patients with substantial electrolyte losses resulting from conditions such as protracted nasogastric suctioning, vomiting, diarrhea, or GI fistula drainage.

4.5 Drug Indication

This intravenous solution is indicated for use in adults and pediatric patients as a source of electrolytes and water for hydration. Also, designed for use as a diluent and delivery system for intermittent intravenous administration of compatible drug additives.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Sodium, the major cation of the extracellular fluid, functions primarily in the control of water distribution, fluid balance, and osmotic pressure of body fluids. Sodium is also associated with chloride and bicarbonate in the regulation of the acid-base equilibrium of body fluid. Chloride, the major extracellular anion, closely follows the metabolism of sodium, and changes in the acid-base balance of the body are reflected by changes in the chloride concentration.

5.4 Absorption, Distribution and Excretion

Absorption

Absorption of sodium in the small intestine plays an important role in the absorption of chloride, amino acids, glucose, and water. Chloride, in the form of hydrochloric acid (HCl), is also an important component of gastric juice, which aids the digestion and absorption of many nutrients.


Route of Elimination

Substantially excreted by the kidneys.


Volume of Distribution

The volume of distribution is 0.64 L/kg.


The primary route of sodium excretion is the urine; additional excretion occurs in sweat and feces. The kidney filters sodium a the glomerulus, but 60% to 70% is reabsorbed in the proximal tubules along with bicarbonate and water. Another 25% to 30% is reabsorbed in the loop of Henle, along with chloride and water. In the distal tubules, aldosterone modulates the reabsorption of sodium and, indirectly, chloride. The renal threshold for sodium is 110 to 130 mEq/L. Less than 1% of the filtered sodium is excreted in the urine.

Dart, R.C. (ed). Medical Toxicology. Third Edition, Lippincott Williams & Wilkins. Philadelphia, PA. 2004., p. 1057


Sodium is rapidly absorbed from the GI tract; it is also absorbed from rectal enemas. Intestinal wall absorption occurs via the Na+, K+-adenosine triphosphatase system that is augmented by aldosterone and desoxycorticosterone acetate. Sodium is not bound by plasma proteins. The volume of distribution is 0.64 L/kg.

Dart, R.C. (ed). Medical Toxicology. Third Edition, Lippincott Williams & Wilkins. Philadelphia, PA. 2004., p. 1057


In one study using radiolabeled 20% sodium chloride injection, most of the drug concentrated in the decidua and the fetal part of the placenta following intra-amniotic injection. Following intra-amniotic administration of 20% sodium chloride injection, some of the drug diffuses into the maternal blood.

American Society of Health-System Pharmacists 2013; Drug Information 2013. Bethesda, MD. 2013, p. 3323


Atrichial sweat glands ... are the organs by which considerable body water and electrolytes, mainly sodium chloride, are lost.

5.5 Metabolism/Metabolites

The salt that is taken in to gastro intestinal tract remains for the most part unabsorbed as the liquid contents pass through the stomach and small bowel. On reaching the colon this salt, together with the water is taken in to the blood. As excesses are absorbed the kidney is constantly excreting sodium chloride, so that the chloride level in the blood and tissues remains fairly constant.Further more, if the chloride intake ceases, the kidney ceases to excrete chlorides. Body maintains an equilibrium retaining the 300gm of salt dissolved in the blood and fluid elements of the tissue dissociated into sodium ions and chloride ions.


5.6 Biological Half-Life

17 minutes


5.7 Mechanism of Action

Sodium and chloride major electrolytes of the fluid compartment outside of cells (i.e., extracellular) work together to control extracellular volume and blood pressure. Disturbances in sodium concentrations in the extracellular fluid are associated with disorders of water balance.


Intra-amniotic instillation of 20% sodium chloride injection induces abortion and fetal death. Although the mechanism has not been conclusively determined, some studies indicate that the drug's abortifacient activity may be mediated by prostaglandins released from decidual cells damaged by hypertonic solutions of sodium chloride. Hypertonic sodium chloride-induced uterine contractions are usually sufficient to cause evacuation of both the fetus and placenta; however, abortion may be incomplete in 25-40% of patients. /20% injection/
