Technescan HDP

TECHNETIUM TC 99M OXIDRONATE

Standard Dose
DOSAGE AND ADMINISTRATION Radiation Safety – Drug Handling After radiolabeling of Technescan HDP, the reaction vial contains Technetium Tc 99m Oxidronate Injection. Handle Technetium Tc 99m Oxidronate Injection with appropriate safety measures to minimize radiation exposure. (See PRECAUTIONS, General .) Use waterproof gloves, effective radiation shielding, and other appropriate safety measures when preparing and handling Technetium Tc 99m Oxidronate Injection. Radiopharmaceuticals should be used by or under the control of healthcare providers who are qualified by specific training and experience in the safe use and handling of radionuclides, and whose experience and training have been approved by the appropriate governmental agency authorized to license the use of radionuclides. Recommended Dosage Adults The recommended amount of radioactivity of Technetium Tc 99m Oxidronate Injection in adults is 555 MBq (15 mCi) with a range of 370 MBq to 740 MBq (10 mCi to 20 mCi). The maximum dose of oxidronate sodium in adults is 2 mg. Pediatric Patients The recommended amount of radioactivity of Technetium Tc 99m Oxidronate Injection in pediatric patients is 7.4 MBq/kg to 13 MBq/kg (0.20 mCi/kg to 0.35 mCi/kg). The recommended minimum and maximum activity in pediatric patients are 37 MBq (1 mCi) and 740 MBq (20 mCi), respectively. The maximum dose of oxidronate sodium in pediatric patients is 2 mg. Administration Instructions Measure the patient dose with a dose calibrator just prior to administration. Administer the dose intravenously by slow injection 1 hour to 4 hours before imaging. To minimize radiation dose to the bladder, encourage the patients to drink fluids before and after administration of Technetium Tc 99m Oxidronate Injection and to void immediately before the examination and as often thereafter as possible for the next 6 hours. (See PRECAUTIONS, General .) Directions for Drug Preparation Procedural Precautions The contents of the vial are intended only for use in the preparation of Technetium Tc 99m Oxidronate Injection and are NOT to be administered directly to the patient. The components of the kit are sterile and non-pyrogenic. Follow the directions carefully and adhere to strict aseptic procedures during preparation. Sodium pertechnetate Tc 99m injection that contains an oxidizing agent or 0.9% sodium chloride injection containing preservatives is not suitable for use in the preparation of Technetium Tc 99m Oxidronate Injection. Wear waterproof gloves during the entire preparation procedure and during subsequent patient dose withdrawals from the reaction vial. Make all transfers of sodium pertechnetate Tc 99m injection using an adequately shielded syringe. Keep the prepared Technetium Tc 99m Oxidronate Injection in the lead vial shield with fitted lead cover in place during the useful life of the radioactive preparation. Make all withdrawals and injection of the Technetium Tc 99m Oxidronate Injection with an adequately shielded syringe. If the dose is for a single adult patient or for pediatric patients, see Directions for the Preparation of a Single Adult Dose or Pediatric Dose(s). Directions for the Preparation of Adult Doses Remove the plastic disc from the Technescan HDP vial and swab the rubber septum with an alcohol swab or a suitable bacteriostatic agent to disinfect the surface. Place the vial in a lead vial shield. Add 3 mL to 6 mL of sodium pertechnetate Tc 99m injection and secure with a fitted lead cover. In choosing the amount of sodium pertechnetate Tc 99m injection radioactivity to be used, the number of doses desired, the activity of each dose, and radioactive decay must be taken into account. The recommended maximum activity of sodium pertechnetate Tc 99m injection to be added to the vial is 11,100 MBq (300 mCi). Shake the vial gently, for approximately 30 seconds, to ensure complete dissolution. Using proper shielding, visually inspect the reaction vial. The resulting solution should be clear and free of particulate matter. If not, do not use the product. Assay the product in a suitable dose calibrator and record the time, date of preparation, and the activity of the Technetium Tc 99m Oxidronate Injection on the radioassay information label and affix it to the vial. Determine the radiochemical purity prior to administration. Store the reaction vial upright in the lead vial shield with fitted lead cover in place at room temperature, 20°C to 25°C (68° to 77°F). Use within 8 hours of radiolabeling. Dispose of unused material in a safe manner in accordance with applicable regulations. Directions for the Preparation of a Single Adult Dose or Pediatric Dose(s) a. Remove the plastic cap from the Technescan HDP vial and swab the rubber septum with an alcohol swab or a suitable bacteriostatic agent to disinfect the surface. b. Add 3 mL to 6 mL of 0.9% sodium chloride injection. Shake the vial gently for approximately 30 seconds to assure complete dissolution. c. Withdraw and discard all but approximately 1 mL of the solution. d. Place the vial in a lead vial shield. Add an appropriate amount of sodium pertechnetate Tc 99m injection for a single adult dose or for one or more pediatric doses and shake gently. No more than 1,480 MBq (40 mCi) should be added to the vial when preparing multiple pediatric doses. e. Proceed with steps 4 through 8 above.

Monitoring

  • • WARNINGS Technetium Tc 99m oxidronate may cause life-threatening hypersensitivity reactions.
  • • Have cardiopulmonary resuscitation equipment and personnel available and monitor all patients for hypersensitivity reactions.
  • • (See ADVERSE REACTION S .) Technetium Tc 99m oxidronate is known to complex cations such as calcium.
  • • Particular caution should be used with patients who have or who may be predisposed to hypocalcemia.

Interaction Notes

  • • Drug Interactions The biodistribution of technetium Tc 99m oxidronate may be altered in the presence of high levels of certain cations (iron, calcium, and aluminum).
  • • This may result in reduced uptake of radionuclide in the skeleton and increased extraosseal uptake, which may potentially degrade imaging quality.
  • • In patients with high levels of these cations caused by concomitant medications, particularly patients receiving iron infusions, consider performing an imaging study with technetium Tc 99m oxidronate injection once the cation levels have normalized (e.g., after 3 to 5 half-lives of the cation).
  • • (See WARNINGS .) Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term animal studies have been performed to evaluate carcinogenic or mutagenic potential or whether technetium Tc 99m oxidronate affects fertility in males and females.
