Bacteriostatic Water for Injection
Bacteriostatic water is water that has been made to inhibit the growth of most types of bacteria. It is comprised of sterile and filtered water, with all bacteria removed, which is then mixed with 0.9% benzyl alcohol, which prevents any contaminating bacteria from growing in the water. In this way, the water has become 'static', or relatively unchanging in its bacterial content.
Bacteriostatic water is used to dilute or dissolve medications for injection. It is different from sterile water, which is filtered and purified but has no additives, and is usually only available for single-use.
