Mechanism of action

This solution contains sodium chloride at a concentration (0.9%) that is isotonic with human blood plasma, meaning it has the same osmotic pressure and does not cause water to move into or out of cells. It is used primarily for fluid replacement, maintaining hydration, and as a vehicle for intravenous drug administration. It is a physiologic solution that restores intravascular volume without causing electrolyte imbalances.
