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