Side Effects & Adverse Reactions

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).

Preliminary reports indicate interference with brain scans using sodium pertechnetate Tc 99m injection which have been preceded by a bone scan using an agent containing stannous ions. This interference may result in false-positive or false-negative brain scans. It is recommended, where feasible, that brain scans precede bone imaging procedures.

Other Information

Each reaction vial contains a sterile, nonpyrogenic, nonradioactive lyophilized mixture of 20 mg medronic acid, 11 mg sodium hydroxide, 1 mg ascorbic acid, 0.13 mg (minimum) stannous fluoride, SnF2 and 0.38 mg total tin, maximum (as stannous fluoride, SnF2).

The pH is adjusted with sodium hydroxide or hydrochloric acid to 6.5 (6.3 to 6.7) prior to lyophilization. The vial does not contain a preservative. The contents of the vial are lyophilized and sealed under nitrogen at the time of manufacture.

The pH of the reconstituted product is 5.4 to 6.8.

The structure of medronic acid is given below:


The precise structure of technetium Tc 99m medronate is unknown at this time.

When sterile, pyrogen-free sodium pertechnetate Tc 99m injection is added to the vial, the diagnostic agent technetium Tc 99m medronate is formed for administration by intravenous injection.
