Sodium Chloride Injection is a widely used pharmaceutical preparation that plays a crucial role in medical practice. It is a fundamental solution for maintaining fluid and electrolyte balance in the human body. This product description aims to provide comprehensive information about its composition, characteristics, indications, usage, and other essential aspects to ensure its safe and effective application.

The primary active ingredient is sodium chloride (NaCl), chemically pure and of pharmaceutical grade. It is dissolved in water for injection, which serves as the vehicle. The concentration of sodium chloride can vary, with the most common being 0.9%, closely mimicking the osmolarity of human plasma. This isotonic formulation allows for seamless integration into the body's extracellular fluid compartment, minimizing disruptions to normal physiological processes. In addition to the standard 0.9% concentration, there are also other variants like 0.45% (used in specific clinical scenarios where a more hypotonic solution is required) and higher concentrations for particular therapeutic needs.
