Question

what type of water is used for preparing soluble injectables

Answer 1

Water is an essential constituent of all body tissues and accounts for approximately 70% of total body weight.  Average normal adult daily requirement ranges from two to three liters (1 to 1.5 liters each for insensible water loss by perspiration and urine production).

Water balance is maintained by various regulatory mechanisms.  Water distribution depends primarily on the concentration of electrolytes in the body compartments and sodium (Na+) plays a major role in maintaining physiologic equilibrium.

The small volume of fluid provided by Sterile Water for Injection, USP when used only as a pharmaceutic aid for diluting or dissolving drugs for parenteral injection, is unlikely to exert a significant effect on fluid balance except possibly in newborns or very small infants

Answer 2

water use for soluble injections are colorless,clear,odourless,tasteless and particle free liquid with pH range from 5.6 to 7.7.

Water for Injections is used to dissolve or dilute substances or preparations for parenteral administration.It contains no anti-microbial agents.
