Contraindications:

Contraindications section for radiogenix system 1.2 none.

Adverse Reactions:

Adverse reactions section for radiogenix system 1.2 the following adverse reactions are described elsewhere in the labeling: radiation exposure risk [see warnings and precautions (5.1)] unintended mo-99 exposure [see warnings and precautions (5.2)] hypersensitivity reactions [see warnings and precautions (5.3)] 6.1 postmarketing experience the following adverse reactions associated with the use of sodium pertechnetate tc 99m injection have been identified in postmarketing experience. because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. allergic reactions (skin rash, hives, or itching) including anaphylaxis have been reported following the administration of sodium pertechnetate tc-99m.

Use in Specific Population:

Use in specific populations for radiogenix system 1.2 8.1 pregnancy risk summary there are no available data with sodium pertechnetate tc-99m use in pregnant women to inform any drug-associated risks of developmental outcomes. animal reproductive studies have not been conducted with sodium pertechnetate tc-99m. all radiopharmaceuticals, including sodium pertechnetate tc-99m, have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose. if considering sodium pertechnetate tc-99m administration to a pregnant woman, inform the patient about the potential for adverse pregnancy outcomes based on the radiation dose from sodium pertechnetate tc-99m and the gestational timing of exposure. the estimated background risk of major birth defects and miscarriage for the indicated population is unknown. all pregnancies have a background risk of birth defects, loss, or other adverse outcomes. in the u.s. general population, the estimated ba
ckground risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. 8.2 lactation risk summary there are limited data available in the published literature on the presence of technetium tc-99m in human milk. there are no data available on the effects of sodium pertechnetate tc-99m on the breast fed infant or the effects on milk production. exposure of sodium pertechnetate tc-99m to a breastfed infant can be minimized by temporary discontinuation of breast feeding (see clinical considerations). the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for sodium pertechnetate tc-99m, any potential adverse effects on the breastfed child from sodium pertechnetate tc-99m or from the underlying maternal condition. clinical considerations to decrease radiation exposure to the breastfed infant, advise a lactating woman to pump and discard breastmilk after the administration of sodium pertechnetate tc-99m for 12 to 24 hours, where the duration corresponds to the typical range of administrated activity, 259 mbq to 925 mbq ( 7 mci to 25 mci). 8.4 pediatric use safety and effectiveness have been established for sodium pertechnetate tc-99m in pediatric patients from birth (term neonates) to 17 years of age for thyroid imaging and for urinary bladder imaging via direct isotopic cystography for the detection of vesicoureteral reflux based on clinical experience. safety and effectiveness have not been established in pediatric patients for salivary gland imaging or nasolacrimal drainage system imaging. although dose adjustment based on body size or weight is generally recommended, the administered dose should be adequate to obtain acceptable quality diagnostic information [see dosage and administration 2.4]. radiation risks of sodium pertechnetate tc 99m injection are greater in pediatric patients than adults [see warnings and precautions (5.1)]. 8.5 geriatric use studies on the relationship of age to the effects of sodium pertechnetate tc 99m injection have not been performed in the geriatric population. other reported clinical experience has not identified differences in responses between the elderly and younger patients. in general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Description section for radiogenix system 1.2 11.1 chemical characteristics the radiogenix system provides sodium pertechnetate tc 99m injection, usp for intravenous use, intravesicular use, ophthalmic use, or for preparing radiopharmaceutical kits. the radiogenix system uses a non-uranium potassium molybdate mo-99 source solution to produce sodium pertechnetate tc 99m injection, usp. the radiogenix® system uses potassium molybdate mo-99 sources at an activity of 7.5 ci (277.5 gbq), 12 ci (444 gbq), 15 ci (555 gbq), and 19 ci (703 gbq) at the date and time of calibration. elution of radiogenix system produces sodium pertechnetate tc-99m (na99mtco4) in approximately 5 ml of sterile 0.9% sodium chloride injection, usp solution. the activity of sodium pertechnetate tc-99m produced varies (4 mci/ml to 2,135 mci/ml of technetium tc-99m) and depends on the activity of potassium molybdate mo-99 present in the source container originally, the decay time since the calibration time, and the elapsed time since the previous sodium pertechnetate tc-99m elution. sodium pertechnetate tc-99m is an inorganic compound with the formula na99mtco4. in solution, sodium pertechnetate exists as dissociated na+ cations and pertechnetate tco4- anions with the following molecular structure: the eluted sodium pertechnetate tc 99m injection, usp is a sterile, non-pyrogenic, clear, and colorless solution. the ph of the solution is between 4.5 and 7.5. 11.2 physical characteristics technetium tc-99m technetium tc-99m decays by isomeric transition with a physical half-life of 6.01 hours. the principal photon that is useful for detection and imaging studies is shown in table 7. table 7 principal radiation emission data technetium tc-99m radiation mean percent per disintegration energy (kev) gamma-2 88.5 140.5 the air-kerma-rate (exposure-rate) constant for technetium tc-99m is 5.23 m2·pgy·(mbq)-1·s-1 [0.795 cm2·r·(mci)-1·h-1]. a range of values for the relative radiation attenuation by the various thicknesses of pb is shown in table 8. for example, the use of 3 mm thickness of pb will attenuate the radiation exposure by a factor of about 1,000. table 8 radiation attenuation by lead shielding shield thickness (pb) mm coefficient of attenuation 0.25 0.5 1 10 -1 2 10 -2 3 10 -3 4 10 -4 molybdenum mo-99 molybdenum mo-99 decays to technetium tc-99m with a molybdenum mo-99 half-life of 66 hours. this means that 77.7% of the activity remains after 24 hours; 60.4% remains after 48 hours, see table 9. table 9 molybdenum mo-99 decay chart half- life 66.0 hours days percent remaining days percent remaining 0 * 100 10 8 1 77.7 11 6.3 2 60.4 12 4.9 3 46.9 13 3.8 4 36.5 14 2.9 5 28.4 15 2.3 6 22 20 0.6 7 17.1 25 0.2 8 13.3 30 0.1 9 10.3 * calibration time the physical decay characteristics of molybdenum mo-99 are such that 88.6% of the decaying molybdenum mo-99 atoms form technetium tc-99m. radiogenix system elutions may be made at any time, but the amount of technetium tc-99m available will depend on the time interval measured from the last elution cycle. eluting the radiogenix system every 24 hours will provide the maximal yield of sodium pertechnetate tc-99m. to correct for physical decay of technetium tc-99m, the fractions that remain at selected intervals of time are shown in table 10. table 10 physical decay chart. technetium tc-99m, half-life 6.01 hours hours percent remaining hours percent remaining 0 * 100 7 44.7 1 89.1 8 39.8 2 79.4 9 35.5 3 70.8 10 31.6 4 63.1 11 28.2 5 56.2 12 25.1 6 50.1 * calibration time sodium perte 7.5ci 15ci 19ci

Clinical Pharmacology:

Clinical pharmacology section for radiogenix system 1.2 12.1 mechanism of action the pertechnetate ion distributes in the body similarly to the iodide ion, but is not organified. in contrast to the iodide ion, the pertechnetate is released unchanged from the thyroid gland. 12.2 pharmacodynamics pertechnetate concentrates in the thyroid gland, salivary glands, gastric mucosa and choroid plexus. after intravenous administration, it equilibrates with the extracellular space. following the administration of sodium pertechnetate tc-99m as an eye drop, the drug mixes with tears within the conjunctival space. within seconds to minutes it leaves the conjunctival space and escapes into the inferior meatus of the nose through the nasolacrimal drainage system. during this process the pertechnetate ions pass through the canaliculi, the lacrimal sac, and the nasolacrimal duct. in the event of any anatomical or functional blockage of the drainage system there will be a backflow resulting in tearing
(epiphora). thus, the pertechnetate escapes the conjunctival space in the tears. the majority of the pertechnetate escapes within a few minutes of normal drainage and tearing. 12.3 pharmacokinetics times to peak concentrations of pertechnetate following intravenous administration are 3.5 hours for cerebral spinal fluid (csf) and 0.25 to 2 hours for thyroid (euthyroid patients). the disappearance of pertechnetate from plasma is biexponential with an initial phase of 10 minutes and a terminal phase of 3 hours. the corresponding phases in csf are less than 1 hour and 11-12 hours, respectively. distribution : pertechnetate distributes throughout the body concentrating in the gastric mucosa, thyroid gland, salivary glands, and urinary bladder. elimination : excretion : elimination by urinary route is 27% in 1 day, 31% in 4 days, and 34% in 8 days based on rate of excretion
