Indications and Usage:
Indications & usage mdp-25 (kit for the preparation of technetium tc 99m medronate) may be used as a bone imaging agent to delineate areas of altered osteogenesis.
Warnings:
Warnings this class of compounds is known to complex cations such as calcium. particular caution should be used with patients who have, or who may be predisposed to, hypocalcemia (i.e., alkalosis). the contents of the kit before preparation are not radioactive. however, after the sodium pertechnetate tc-99m is added, adequate shielding of the final preparation must be maintained. preliminary reports indicate impairment of brain images using sodium pertechnetate tc 99m injection which have been preceded by bone imaging using an agent containing stannous ions. the impairment may result in false-positive or false-negative brain images. it is recommended, where feasible, that brain imaging using sodium pertechnetate tc 99m injection precede bone imaging procedures. alternatively, a brain imaging agent such as technetium tc-99m pentetate may be employed.
Dosage and Administration:
Dosage and administration the recommended adult dose, after reconstitution with oxidant-free sodium pertechnetate tc-99m, is 370 to 740 megabecquerels (10 to 20 millicuries [200 µci/kg]) by slow intravenous injection over a period of 30 seconds. optimum scanning time is 1 to 4 hours post-injection. to minimize the contribution of the bladder content to the image, the patient should void immediately before imaging is started. the patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration. parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. the solution should not be used if cloudy. radiation dosimetry the estimated absorbed radiation doses to an average patient (70 kg) from an intravenous injection of a maximum dose of 740 megabecquerels (20 millicuries) of technetium tc 99m medronate are shown in table 4. the effective half-life was assumed to be the physical h

Description:
Draximage ® mdp-25 kit for the preparation of technetium tc 99m medronate injection for intravenous use diagnostic â for skeletal imaging description the kit consists of reaction vials which contain the sterile, non-pyrogenic,non-radioactive ingredients necessary to produce technetium tc 99m medronate injection for diagnostic use by intravenous injection. mdp-25 reaction vials are intended to be used as multidose vials. each 10 ml mdp-25 reaction vial contains 25.0 mg medronic acid and not less than 2.0 mg of stannous chloride dihydrate (maximum total tin expressed as stannous chloride dihydrate 3.0 mg) and 5.0 mg of p-aminobenzoic acid in lyophilized form under an atmosphere of nitrogen. the ph is adjusted to 6.8 to 6.9 with hci or naoh prior to lyophilization. the addition of sterile, non-pyrogenic, and oxidant-free sodium pertechnetate tc-99m sterile solution produces a rapid labeling which is essentially quantitative and which remains stable in vitro throughout the 12-hours life of the preparation. no bacteriostatic preservative is present. the structural formula of medronic acid is: physical characteristics technetium tc-99m decays by isomeric transition with a physical half-life of 6.02 hours. 1 the principal photon that is useful for detection and imaging studies is listed in table 1. table 1 principal radiation emission data radiation mean % / disintegration energy (kev) gamma-2 89.07 140.5 external radiation the specific gamma ray constant for tc-99m is 0.78 r/mci-hr at 1 cm. the first half value layer is 0.017 cm of lead. to facilitate control of the radiation exposure from millicurie amounts of this radionuclide, the use of a 0.25 cm thickness of lead will attenuate the radiation emitted by a factor of about 1000. a range of values for the relative attenuation of the radiation emitted by this radionuclide that results from interposition of various thicknesses of lead is shown in table 2. table 2 radiation attenuation by lead shielding shield thickness (pb) cm coefficient of attenuation 0.017 0.08 0.16 0.25 0.33 0.5 10 -1 10 -2 10 -3 10 -4 to correct for physical decay of this radionuclide, the fractions that remain at selected intervals after the time of calibration are shown in table 3. 1 kocher, david c.: âradioactive decay data tablesâ, doe/tic-11026, 108 (1981) table 3 physical decay chart: tc-99m, half-life 6.02 hours *calibration time hours fraction remaining hours fraction remaining 0* 1 2 3 4 5 6 1.000 0.891 0.794 0.708 0.631 0.562 0.501 7 8 9 10 11 12 0.447 0.398 0.355 0.316 0.282 0.251
Clinical Pharmacology:
Clinical pharmacology when injected intravenously, technetium tc 99m medronate is rapidly cleared from the blood; about 50% of the dose is accumulated and retained by the skeleton, while the remaining 50% is excreted in the urine within 24 hours. about 10% of the injected dose remains in the blood at 1 hour post-injection, 5% at 2 hours, and less than 1% remains at 24 hours. the resultant blood clearance curve is tri-exponential with the two fastest components accounting for all but a few percent of the injected dose. following intravenous administration of technetium tc 99m medronate, skeletal uptake occurs as a function of blood flow to bone and bone efficiency in extracting the complex. bone mineral crystals are generally considered to be hydroxyapatite, and the complex appears to have an affinity for the hydroxyapatite crystals in the bone. the rapid blood clearance provides bone to soft-tissue ratios which favor early imaging. the skeletal uptake is bilaterally symmetrical and is
