Well depending on some unknown

stability process, we might have 7 days.

"Abstract:
OBJECTIVE: The purpose of this study was to determine the stability of oxytocin in

lactated Ringer's solution and lactated Ringer's-dextrose 5% solution over a 24-hour period at 25[degrees]C and

over a 7-day period at 5[degrees]C.
STUDY DESIGN: Twenty units (2.1 [mu]g equal 1 unit) of oxytocin were injected

into 1000 mL of lactated Ringer's solution and lactated Ringer's-dextrose 5% solution. Samples for the analysis

were drawn at specified times after storage at 5[degrees]C and 25[degrees]C. These samples were stored at

-70[degrees]C for later analysis. Statistical analysis was done with 1-way analysis of variance and Tukey-Kramer

multiple comparisons.
RESULTS: Twenty units of oxytocin in 1000 mL of lactated Ringer's solution and lactated

Ringer's-dextrose 5% solution was found to be stable for 7 days at 5[degrees]C and for 24 hours at

25[degrees]C."
