    Area of Science:

    • Radiopharmacy
    • Medical Isotope Production
    • Nuclear Medicine

    Background:

    • The 82Sr/82Rb radionuclide generator is crucial for producing 82Rb for positron emission tomography (PET) imaging.
    • Ensuring the pharmaceutical quality and safety of eluates is paramount for patient administration.

    Purpose of the Study:

    • To describe a 82Sr/82Rb generator system suitable for continuous intravenous infusion in humans.
    • To detail methods for ensuring the sterility, pyrogen-freeness, and minimal radionuclide impurity of the eluate.
    • To provide recommendations for maintaining the generator's pharmaceutical integrity.

    Main Methods:

    • Continuous intravenous infusion of the 82Sr/82Rb generator system in human subjects.
    • Close monitoring of 82Sr (strontium-82) parent breakthrough levels in the eluate.
    • Disinfection of the generator using a 0.05% sodium hypochlorite solution to achieve sterility and pyrogen-freeness.

    Main Results:

    • The 82Sr/82Rb generator system was successfully demonstrated for continuous intravenous infusion.
    • 82Sr parent breakthrough was consistently maintained below 18.5 Bq mL-1 of infusate.
    • The sodium hypochlorite disinfection method yielded a sterile and pyrogen-free eluate.

    Conclusions:

    • The described 82Sr/82Rb generator system is suitable for clinical use in continuous intravenous infusion.
    • Effective monitoring and disinfection protocols are essential for safe and reliable eluate production.
    • Adherence to recommended setup procedures ensures the pharmaceutical integrity of the generator system.
