Bacteriostatic Sterile Water for Injection and Bacteriostatic Sodium Chloride are pharmaceutical products used primarily as diluents for medications that need to be administered via injection. These solutions help in diluting or dissolving drugs for intravenous (IV), intramuscular (IM), or subcutaneous (SQ) injection, ensuring the correct concentration and dosage. The "bacteriostatic" component refers to the presence of an antimicrobial agent that inhibits the growth of bacteria, providing a longer shelf life for multi-dose vials.
