1. Why am I using RADPHARM DTPA?

RADPHARM DTPA contains the active ingredient Pentetic acid. RADPHARM DTPA is a prescription medicine which is only available to the Healthcare Practitioners for diagnostic use only. It belongs to a group of medicines called radiopharmaceutical agents, which are radioactive. It is administered to you via intravenous injection after mixing with a radioactive solution.

RADPHARM DTPA is mixed with Technetium (99mTc) before injection. RADPHARM DTPA is used to image renal perfusion.

Your doctor may have prescribed RADPHARM DTPA for another purpose. Ask your doctor if you have any questions about why RADPHARM DTPA has been prescribed for you. If you have any concerns, you should discuss these with your doctor.

2. What should I know before I use RADPHARM DTPA?

Warnings

Procedure.

Note.

If there is no vacuum, discard vial and do not deliver the sodium pertechnetate [99mTc] injection.
1. Place Radpharm DTPA vial in a shielding container.
2. Draw a suitable volume (1 to 4 mL) of sodium pertechnetate [99mTc] injection eluted from a technetium-99m generator (1 to 3 GBq) and inject into the Radpharm DTPA vial. Mix by inversion for 30 seconds and leave standing at room temperature for 10 minutes before use.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

For each patient, exposure to ionising radiation must be justifiable on the basis of likely benefit. The activity administered must be such that the resulting dose is as low as reasonably achievable bearing in mind the need to obtain the intended diagnostic or therapeutic result.
Exposure to ionising radiation is linked with cancer induction and a potential for development of hereditary defects. For diagnostic nuclear medicine investigations the current evidence suggests that these adverse effects will occur with low frequency because of the low radiation doses incurred.
For most diagnostic investigations using a nuclear medicine procedure the radiation dose delivered (EDE) is less than 20 mSv. Higher doses may be justified in some clinical circumstances.
In isolated cases the following adverse reactions have been reported: flushing, dizziness, dyspnoea, itch, urticaria and hypotension.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Physical characteristics of technetium-99m.

Technetium-99m with a physical half life of 6 hours decays by isomeric transition to technetium-99. Photons associated with this transition that are useful for detection and imaging studies are listed. See Tables 2 and 3.

External radiation.

The specific gamma ray constant for technetium-99m is 0.19 mGy/MBq-h at 1 cm. The first half value thickness of lead (Pb) for technetium-99m is 0.2 mm. Attenuation by lead is given in Table 4.

Clinical trials.

No data available.

5.2 Pharmacokinetic Properties

Following intravenous administration of technetium [99mTc] pentetate to normal patients the radiopharmaceutical is rapidly distributed in the extracellular fluid space then cleared from the body through the kidneys. There is minimal binding to renal parenchyma and it clears the kidneys by glomerular filtration.
The images taken in the first minutes demonstrate kidney vascular pool and subsequent images represent technetium [99mTc] pentetate in both the collecting system and the renal pelvis.

5.3 Preclinical Safety Data

Genotoxicity.

No data available.

Carcinogenicity.

No data available.
