DEFINITION

Technetium Tc 99m Medronate Injection is a sterile, aqueous solution, suitable for intravenous administration, of sodium medronate and stannous chloride or stannous fluoride that is labeled with radioactive technetium (^99mTc). It contains NLT 90.0% and NMT 110.0% of the labeled amount of ^99mTc as stannous medronate complex expressed in megabecquerels (microcuries or millicuries) per milliliter at the date and time indicated in the labeling. Other chemical forms of radioactivity are NMT 10.0% of the total radioactivity. It may contain antimicrobial agents, antioxidants, and buffers.
