Technetium Tc-99m medronate disodiumProduct ingredient for Technetium Tc-99m medronate
- Name
- Technetium Tc-99m medronate disodium
- Drug Entry
- Technetium Tc-99m medronate
Technetium (99mTc) medronic acid is a pharmaceutical product used in nuclear medicine imaging. It is composed of a technetium ion complexed with medronic acid, a type of bisphosphonate. Like other bisphosphonates used in the treatment of osteoporosis, medronic acid binds to the hydroxyapatite crystals within bone, and in this way localizes the drug to bone for delineation of areas of altered osteogenesis. Following intravenous injection, single photon emission computed tomography (SPECT) is performed to detect the gamma ray emmitted by the decay of Technetium-99m to Technetium-99.
