Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Technetium-99m methylene diphosphonate (MDP) is a bone-seeking radiopharmaceutical. After intravenous injection, it adsorbs onto hydroxyapatite crystals in bone, with increased uptake in areas of high metabolic activity or blood flow, such as tumors or fractures. The technetium-99m emits gamma rays which are detected by a gamma camera for imaging.
Technetium Tc-99m mebrofenin is a radiopharmaceutical that, after intravenous administration, is taken up by hepatocytes and excreted into the biliary system. It allows scintigraphic imaging of the liver and biliary tract by emitting gamma rays detectable by a gamma camera.
555–925 MBq (15–25 mCi) intravenously for bone scintigraphy; imaging performed 2–4 hours post-injection
Adults: 1-5 mCi (37-185 MBq) IV bolus. Image immediately and at intervals up to 60 minutes for hepatobiliary scintigraphy.

Clinical Note
moderateTechnetium Tc-99m mebrofenin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Technetium Tc-99m mebrofenin."
Clinical Note
moderateTechnetium Tc-99m mebrofenin + Eltrombopag
"The serum concentration of Eltrombopag can be increased when it is combined with Technetium Tc-99m mebrofenin."
Terminal elimination half-life is approximately 6-8 hours for the primary complex; minor radiochemical impurities may have longer half-lives
Terminal elimination half-life: approximately 6 hours (range 4-8 hours) in patients with normal hepatic function. In obstructive jaundice, half-life may be prolonged due to delayed biliary excretion.
Primarily renal (urinary excretion of 60-70% as unchanged drug within 24 hours, with 5-10% biliary excretion)
Primarily biliary (hepatobiliary) excretion: ~75% of administered activity is excreted into bile and subsequently into feces within 24 hours. Renal excretion accounts for <10% of the administered dose.
