Packaging and storage
Preserve in single-dose
Containers for Injections that are adequately shielded as described under
Injections 1, and store at controlled room temperature.
Labeling
Label it to include the following, in addition to the information specified for
Labeling under
Injections 1: the time and date of calibration; the amount of
99mTc as labeled arcitumomab expressed as total MBq (or mCi) per mL, at the time of calibration; the expiration date and time; the storage temperature; and the statement CautionRadioactive Material. The labeling indicates that, in making dosage calculations, correction is to be made for radioactive decay, and also indicates that the radioactive half-life of
99mTc is 6.0 hours. The labeling also states that it should be used within 4 hours following constitution.
Bacterial endotoxins 85
The limit of endotoxin content is not more than 175/
V USP Endotoxin Unit per mL of the Injection, when compared with the USP Endotoxin RS, in which
V is the maximum recommended total dose, in mL, at the expiration date and time.
Radiochemical purity
To determine the amount of free technetium, apply 1 µL of the Injection about 2.7 cm from the bottom of a 1-cm × 9-cm instant thin-layer chromatographic silica gel strip (see
Chromatography 621). Immediately develop the chromatogram over a period of 4 minutes by ascending chromatography using acetone as the solvent. Allow the chromatogram to air-dry. Determine the radioactivity distribution of the chromatogram by scanning with a suitable radiation detector: not more than 5.0% of the total radioactivity is found at the solvent front as unbound pertechnetate.
Other requirements
It meets the requirements for
Radionuclide identification and
Radionuclidic purity under
Sodium Pertechnetate Tc 99m Injection. It meets also the requirements under
Injections 1, except that it may be distributed or dispensed prior to completion of the test for
Sterility, the latter test being started on the date of manufacture.
Assay for radioactivity 821
Using a suitable counting assembly (see
Selection of a Counting Assembly), determine the radioactivity, in MBq (or mCi) per mL, of Injection by use of a calibrated system.
