Each 5 mL vial contains a sterile, non-pyrogenic, lyophilized mixture of: Tetrakis (2-methoxy isobutyl isonitrile) Copper (I) tetrafluoroborate - 1.0 mg Sodium Citrate Dihydrate - 2.6 mg L-Cysteine Hydrochloride Monohydrate - 1.0 mg Mannitol – 20 mg Stannous Chloride, Dihydrate, minimum (SnCl 2 ∙2H 2 O) - 0.025 mg Stannous Chloride, Dihydrate, (SnCl 2 ∙2H 2 O) - 0.075 mg Tin Chloride (stannous and stannic) Dihydrate, maximum (as SnCl 2 ∙2H 2 O) - 0.086 mg Prior to lyophilization the pH is 5.3 to 5.9. The contents of the vial are lyophilized and stored under nitrogen. This drug is administered by intravenous injection for diagnostic use after reconstitution with sterile, non-pyrogenic, oxidant-free Sodium Pertechnetate Tc99m Injection. The pH of the reconstituted product is 5.5 (5.0 - 6.0). No bacteriostatic preservative is present. The precise structure of the technetium complex is Tc99m[MIBI] 6 + where MIBI is 2-methoxy isobutyl isonitrile. 11.1 Physical Characteristics Technetium Tc99m decays by isomeric transition with a physical half-life of 6.02 hours Kocher, David, C., Radioactive Decay Data Tables, DOE/TIC-11026, 108(1981). . Photons that are useful for detection and imaging studies are listed below in Table 3.0. Table 3.0. Principal Radiation Emission Data Radiation Mean %/Disintegration Mean Energy (KeV) Gamma -2 89.07 140.5 11.2 External Radiation The specific gamma ray constant for Tc99m is 5.4 microcoulombs/Kg-MBq-hr (0.78R/mCi-hr) at 1 cm. The first half value layer is 0.017 cm of Pb. A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from interposition of various thicknesses of Pb is shown in Table 4.0. To facilitate control of the radiation exposure from Megabequerel (millicurie) amounts of this radionuclide, the use of a 0.25 cm thickness of Pb will attenuate the radiation emitted by a factor of 1,000.
