» Technetium Tc 99m Oxidronate Injection is a sterile, clear, colorless solution, suitable for intravenous administration, of radioactive technetium (^99mTc) in the form of a chelate of oxidronate sodium. It contains not less than 90.0 percent and not more than 110.0 percent of the labeled amount of ^99mTc as chelate expressed in megabecquerels (microcuries or millicuries) per mL at the time indicated in the labeling. It may contain buffers, preservatives, reducing agents, and stabilizers. Other chemical forms of radioactivity do not exceed 10.0 percent of the total radioactivity.
