RADPHARM MDP contains the active ingredient Medronic acid. RADPHARM MDP 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 MDP is mixed with Technetium (99mTc) before injection. RADPHARM MDP is used for imaging the skeletal system.

Your doctor may have prescribed RADPHARM MDP for another purpose. Ask your doctor if you have any questions about why RADPHARM MDP 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 MDP?

Procedure.

Note.

If there is no vacuum, discard vial and do not deliver the sodium pertechnetate [99mTc] injection.
1. Place Radpharm MDP vial in a shielding container.
2. Draw a suitable volume (2 to 8 mL) of sodium pertechnetate [99mTc] injection eluted from a technetium-99m generator (1 to 16 GBq), and inject into the Radpharm MDP vial. Mix by inversion for 20 seconds and leave standing at room temperature for 10 minutes before use.

(Category C)
Technetium-99m radiopharmaceuticals should only be given to a pregnant woman if in the judgement of the treating physician the expected benefits outweigh the potential hazards.
Technetium-99m is excreted in human milk. Interruption to breast feeding is not essential after the administration of a technetium [99mTc] medronate (a mother can be reassured by advising an interruption of 4 hr).
(Reference: L.K. Harding, A. Bossuyt, S. Pellet, C. Reiners, J.N. Talbot, "Recommendations for nuclear medicine physicians regarding breastfeeding mothers", Eur. J. Nucl. Med., 1995, 22, BP17).

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.
Occasionally (approximately 0.5 out of 100,000 investigations), hypersensitivity reactions may occur following intravenous administration of technetium [99mTc] medronate. Cases of local rash or generalised rash with itching and dermal irritation have been reported. Onset of the reaction is commonly several hours post-injection and it may last up to 48 hours. Treatment with a non-selective histamine H1 antagonist is helpful.

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 in 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

After intravenous administration of technetium [99mTc] medronate, skeletal uptake appears to be related to bone metabolic activity and skeletal blood flow. Technetium [99mTc] medronate demonstrates specific affinity for areas of altered osteogenesis.
Localised areas of decreased bone uptake may occur after therapeutic external irradiation.
Blood clearance of technetium [99mTc] medronate is multiexponential with an initial fall in blood concentration with half-time (t1/2 = 3.5 minutes), followed by medium (t1/2 = 27 minutes) and slow (t1/2 = 144 minutes). The initial blood clearance represents the relatively rapid movement of technetium [99mTc] medronate from the vascular compartments to other compartments. The other clearance rates are functions of bone uptake and renal clearance and protein binding of tracer. Blood levels fall to 3-5% of the injected dose by 3 hours post injection.

5.3 Preclinical Safety Data

Genotoxicity.

No data available.

Carcinogenicity.

No data available.
