BRAND NAME: N/A

DRUG CLASS AND MECHANISM: Our body cells are bathed in a watery fluid that contains primary sodium and chloride ions. These molecules play a vital role in maintaining proper fluid balance and keeping our tissues hydrated. Additionally, sodium is involved in many cell processes such as muscle contraction, transmission of nerve impulses, and kidney function. Chloride ions are responsible for maintaining the acid-base balance. To sustain life it's very important to maintain these ions within a narrow therapeutic range.

Sodium chloride is available in a variety of formulations including:

  • nasal gel,
  • nasal spray,
  • nasal wash,
  • nebulizer solution,
  • ophthalmic (eye) drops,
  • ophthalmic ointment,
  • topical solution for irrigation,
  • diluent for injection,
  • topical spray, and
  • solution for intravenous (into the vein) injection.

Sodium chloride was initially approved by the FDA in 1951.

  • During the treatment of shock and other conditions in which additional fluids are needed to maintain blood pressure
  • During cases of sodium and chloride depletion, an IV hypertonic saline (3% or 5% sodium chloride solution) is administered to correct and replace sodium and chloride.
  • As a delivery vehicle for the administration of compatible injectable medicines and to flush IV lines
  • To replenish fluids and sodium chloride during periods of dehydration
  • In medical conditions in which additional fluids are needed
