Iobenguane I 123Product ingredient for Iobenguane
- Name
- Iobenguane I 123
- Drug Entry
- Iobenguane
Synthetic guanethidine derivative that locates phaeochromocytomas and neuroblastomas. The radioisotope used can either be iodine-123 for imaging or iodine-131 for destruction of tissues that metabolize noradrenaline. Iodine 123 is a cyclotron-produced radionuclide that decays to Te 123 by electron capture. Images are produced by a I123 MIBG scintigraphy. FDA approved on September 19, 2008.
