Strontium Chloride SR-89 Description
Strontium Chloride SR-89 INJECTION, USP is a sterile, non-pyrogenic, aqueous solution of Strontium-89 Chloride for intravenous administration. The solution contains no preservative. Each milliliter contains:
Strontium Chloride 10.9 - 22.6 mg
Water for Injection q.s. to 1 mL
The radioactive concentration is 37 MBq/mL, 1 mCi/mL, and the specific activity is 2.96-6.17 MBq/mg, 80-167 µCi/mg at calibration. The pH of the solution is 4 - 7.5.
PHYSICAL CHARACTERISTIC
Strontium-89 decays by beta emission with a physical half-life of 50.5 days. The maximum beta energy is 1.463 MeV (100%). The maximum range of ß- particles from Strontium-89 in tissue is approximately 8 mm.
Radioactive decay factors to be applied to the stated value for radioactive concentration at calibration, when calculating injection volumes at the time of administration, are given in Table 1.
