What is Atosiban CAS 90779-69-4
Atosiban (CAS 90779-69-4) is an intravenous medication that inhibits the hormones oxytocin and vasopressin.
What is Bac Water
"Bac Water" is a shortened term for Bacteriostatic Water, which is sterile water containing 0.9% benzyl alcohol as a preservative to inhibit bacterial growth. It is used to dilute or dissolve medications for injection, particularly when the vial will be used multiple times, such as for subcutaneous, intravenous, or intramuscular injections. The preservative allows multi-dose vials to be reused over a period of time without the risk of contamination.

The key benefit of bacteriostatic water is its ability to prevent bacterial contamination, thus making it safer for multi-use applications. This is especially beneficial in medical settings, where the same vial may be used multiple times.
Compared to other diluents like sterile water, saline, or dextrose water, bacteriostatic water can offer better stability for certain medications. The benzyl alcohol present acts as a preservative, keeping the medication effective and safe for longer periods.
How Atosiban CAS 90779-69-4 Works
Atosiban CAS 90779-69-4 works by blocking oxytocin receptors in the uterus, preventing contractions. By inhibiting these contractions, it helps delay preterm labor and provides more time for the baby`s growth before birth.
How to Store Bacteriostatic Water
Storage guidelines for bacteriostatic water are crucial to maintain its sterility and efficacy. Generally, it should be kept at room temperature, away from light, heat, and moisture.
The shelf life of unopened bacteriostatic water is typically up to two years. However, once opened, the vial should be used within 28 days to maintain safety and efficacy, after which it should be discarded. Always check the expiration date before using, and discard the vial if the solution appears discolored or contains particles.
Should only be used under medical supervision
Not recommended for women with pregnancy complications
Monitor heart rate and blood pressure during treatment
Inform the doctor about any existing medical conditions
Avoid alcohol and smoking during pregnancy


Atosiban CAS 90779-69-4 is used in the prevention of premature labour or premature birth. The detailed uses of Atosiban are as follows: • Prevention of preterm birth: Atosiban is used in prevention of preterm birth in women between 24 and 33 weeks of pregnancy. • Management of early uterine contractions: Atosiban is used in management of early uterine contractions to allow more time for fetal development.
Clinical Medical Personnel
In hospitals or clinics, nurses and doctors frequently need to prepare injection solutions. Using antibacterial solutions can improve preparation efficiency and ensure safety during multiple uses.
Veterinary Medical Professionals
Veterinarians frequently use antibacterial solutions to dilute or reconstitute medications when administering injections to animals.
Patients Injecting at Home
Diabetic patients and patients receiving hormone replacement therapy (such as TRT) often need to inject medication regularly at home. If they need to prepare their own medication, choosing antibacterial solutions as a diluent allows for greater flexibility and reduces the risk of contamination from repeated procedures.
Fitness Enthusiasts and Muscle-Building Individuals (Under Legal Use)
Some fitness enthusiasts need to prepare multiple doses of injectable hormone supplements when using them properly. Antibacterial solutions are also a commonly used auxiliary product for them.
