Mechanism of action

This solution contains sodium and chloride ions in concentrations (0.9% w/v) that are isotonic with human blood plasma, preventing osmotic shifts across cell membranes. It is used for fluid replacement, electrolyte supplementation, and as a vehicle for drug administration. The solution does not exert a pharmacological effect but rather serves as a physiological support agent.
