RUBY-FILL (rubidium chloride rb-82)
RUBY-FILL is a closed generator system used to produce rubidium Rb 82 chloride injection for intravenous administration. It is indicated for Positron Emission Tomography (PET) imaging of the myocardium under rest or pharmacologic stress conditions to evaluate regional myocardial perfusion in adult patients with suspected or existing coronary artery disease.
How RUBY-FILL Works
Rubidium Rb 82 acts as a potassium (K+) analog and is rapidly extracted by the myocardium in proportion to blood flow. The process involves the sodium-potassium (Na+/K+) ion exchange pumps and requires the maintenance of an ionic gradient across cell membranes. Consequently, Rb 82 radioactivity is significantly higher in viable myocardium than in infarcted tissue, allowing for the assessment of tissue viability and perfusion.

RUBY-FILL Boxed Warning
HIGH LEVEL RADIATION EXPOSURE WITH USE OF INCORRECT ELUENT AND FAILURE TO FOLLOW QUALITY CONTROL TESTING PROCEDURE High Level Radiation Exposure with Use of Incorrect Eluent Patients are exposed to high radiation levels when the generator is eluted with the incorrect eluent due to high Sr 82 and Sr 85 breakthrough levels [see Warnings and Precautions ( 5.1 )] Use only additive-free 0.9% Sodium Chloride Injection USP to elute the generator [see Dosage and Administration ( 2.5 )] Immediately stop ...
WARNING: HIGH LEVEL RADIATION EXPOSURE WITH USE OF INCORRECT ELUENT AND FAILURE TO FOLLOW QUALITY CONTROL TESTING PROCEDURE High Level Radiation Exposure with Use of Incorrect Eluent Patients are exposed to high radiation levels when the generator is eluted with the incorrect eluent due to high Sr 82 and Sr 85 breakthrough levels [see Warnings and Precautions ( 5.1 )] Use only additive-free 0.9% Sodium Chloride Injection USP to elute the generator [see Dosage and Administration ( 2.5 )] Immediately stop the patient infusion and discontinue the use of the affected RUBY-FILL (Rb 82) generator, if the incorrect solution is used to elute the generator [see Contraindications ( 4 )]. Evaluate the patient’s radiation absorbed dose and monitor for the effects of radiation to critical organs such as bone marrow [(see Dosage and Administration ( 2.9 )] . Excess Radiation Exposure with Failure to Follow Quality Control Testing Procedure Excess radiation exposure occurs when the levels of Sr 82 or Sr 85 in the rubidium Rb 82 chloride injection exceed specified limits [see Warnings and Precautions ( 5.2 )]. The system automatically generates a record and saves the data for each generator eluate volume, including flushing and test volumes. Total cumulative eluate volumes are also recorded and saved for the life of the generator [see Dosage and Administration ( 2.5 )] . Strictly adhere to the generator quality control testing procedure, to minimize the risk of excess radiation exposure, including daily testing and additional testing at Alert Limits [see Dosage and Administration ( 2.6 )] Stop use of a generator at any of the following Expiration Limits. Expiry Limits are: o 30 L for the generator's cumulative eluate volume, or o Expiration date of the generator (60 days post-calibration) o An eluate Sr 82 level of 0.01 mcCi /mCi (kBq/MBq) Rb 82, or o An eluate Sr 85 level of 0.1 mcCi /mCi (kBq/MBq) Rb 82 [see Dosage and Administration ( 2.7 )].
