GALLIUM CITRATE GA-67 (UNII: 4LJK511Z86) (GALLIUM CATION GA-67 - UNII:99T03J52W0)
Lantheus Medical Imaging, Inc.
GALLIUM CITRATE GA-67
GALLIUM CATION GA-67 2.0 mCi in 1 mL
INTRAVENOUS
PRESCRIPTION DRUG
Gallium Citrate Ga 67 Injection may be useful in demonstrating the presence of the following malignancies: Hodgkins disease, lymphomas and bronchogenic carcinoma. Positive Ga 67 uptake in the absence of prior symptoms warrants follow-up as an indication of a potential disease state. Gallium Citrate Ga 67 Injection may be useful as an aid in detecting some acute inflammatory lesions. None known.
Gallium Citrate Ga 67 Injection is supplied sterile and non-pyrogenic for intravenous use. Each mL contains 74 MBq (2 mCi) of Gallium Ga 67 on the calibration date, as a complex formed from 9 ng Gallium Chloride Ga 67, 2 mg of sodium citrate, 6.8 mg sodium chloride, and 9 mg benzyl alcohol/mL as preservative. The pH is adjusted to between 4.5-8 with hydrochloric acid and/or sodium hydroxide solution. Vials are available in the following quantities of radioactivity: 244.2, 325.6, 488.4, and 732.6 MBq (6.6, 8.8, 13.2, and 19.8 mCi) of Gallium Citrate Ga 67 at calibration. NDC Number 11994-121 Store at controlled room temperature 20°-25°C (68°-77°F) [See USP]. The contents of the vial are radioactive and adequate shielding and handling precautions must be maintained. This radiopharmaceutical is approved for distribution to persons licensed pursuant to the Code of Massachusetts Regulations 105 CMR 120.100 for the uses listed in 105 CMR 120.547 or 120.552 or under equivalent regulations of the U.S. Nuclear Regulatory Commission, an Agreement State, or a Licensing State.

GALLIUM- GALLIUM CITRATE GA-67 INJECTION LANTHEUS MEDICAL IMAGING, INC. ---------- GALLIUM CITRATE GA 67 INJECTION FOR DIAGNOSTIC USE DESCRIPTION Gallium Citrate Ga 67 Injection is supplied in isotonic solution as a sterile, non-pyrogenic diagnostic radiopharmaceutical for intravenous administration. Each milliliter of the isotonic solution contains 74 MBq (2 mCi) of Gallium Ga 67 on the calibration date, as a complex formed from 9 ng Gallium Chloride Ga 67, 2 mg of sodium citrate, 6.8 mg sodium chloride, and 9 mg benzyl alcohol/mL added as preservative. The pH is adjusted to between 4.5-8 with hydrochloric acid and/or sodium hydroxide solution. Gallium Ga 67, with a half-life of 78.3 hours, is cyclotron produced by the proton irradiation of enriched zinc oxide, is essentially carrier-free and contains negligible concentrations of other radioactive isotopes. The radionuclidic composition at calibration time is ≥99.89% Gallium Ga 67, ≤0.01% Gallium Ga 66 and ≤0.1% due to other radiocontaminants, each expressed as a percentage of total activity. The radionuclidic composition at expiration time is ≥99.89% Gallium Ga 67, essentially zero (0.0002%) Gallium Ga 66 and essentially zero of other radiocontaminants each expressed as a percentage of total activity. The chemical structure for Gallium Citrate is shown below: PHYSICAL CHARACTERISTICS Gallium Ga 67 decays to stable Zinc Zn 67 by electron capture with a physical half-life of 78.3 hours. TABLE 1.

The first half value thickness of lead is 0.066 cm. A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from the interposition of various thicknesses of Pb is shown in Table 2. For example, the use of 0.41 cm of Pb will decrease the external radia Lestu allt skjalið
