WARNINGS AND PRECAUTIONS
Radiation Exposure Risk
Sodium Pertechnetate Tc-99m contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Use the lowest dose of Sodium Pertechnetate Tc-99m necessary for imaging and ensure safe handling and preparation to protect the patient and health care worker from unintentional radiation exposure. Encourage patients to drink fluids and void as frequently as possible after intravenous or intravesicular administration. Advise patients to blow their nose and wash their eyes with water after ophthalmic administration [see Dosage and Administration (2.1)].
Radiation risks associated with the use of Sodium Pertechnetate Tc-99m are greater in pediatric patients than in adults due to greater absorbed radiation doses and longer life expectancy. Ensure the diagnostic benefit of Sodium Pertechnetate Tc-99m outweighs these greater risks prior to administration in pediatric patients.
Unintended Mo-99 Exposure
Unintended exposure to Mo-99 radiation contributes to a patient’s overall cumulative radiation dose. To minimize the risk of unintended radiation exposure, strict adherence to the eluate testing protocol is required. Use only potassium molybdate Mo-99, processing reagents, saline, and other supplies, including kits, provided by NorthStar Medical Radioisotopes, LLC. Do not administer Sodium Pertechnetate Tc 99m Injection after the 0.15 microCi of Mo-99/mCi of Tc-99m limit has been reached and discard the Sodium Pertechnetate Tc 99m Injection when the 12 hour expiration time is reached; whichever occurs earlier [see Dosage and Administration (2.7)].
Hypersensitivity Reactions
Hypersensitivity reactions, including serious signs and symptoms of anaphylaxis, following administration of Sodium Pertechnetate Tc 99m Injection have been reported. Always have cardiopulmonary resuscitation equipment and personnel available and monitor all patients for hypersensitivity reactions. -

USE IN SPECIFIC POPULATIONS
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 background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
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).
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 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)].
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
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 1.0a and 1.1 uses potassium molybdate Mo-99 sources at an activity of 6 Ci/29 mL (222 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 solution. The activity of Sodium Pertechnetate Tc-99m produced varies (30 mCi/mL to 1,153 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.
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 8.

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 9. For example, the use of 3 mm thickness of Pb will attenuate the radiation exposure by a factor of about 1,000.

CLINICAL PHARMACOLOGY
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.
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.
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
