General information
Class/mechanism: Radioactive pharmaceutical agent (radium-223) that mimics some biologic behaviors of calcium and is incorporated into areas with increased bone turnover, such as bone metastases, by forming complexes with hydroxyapatite. Radium-223 emits alpha radiation at the site of bone metastases, which causes double-strand DNA breaks in nearby cells. The limited penetration of alpha radiation (less than 100 micrometers/uM, less than 10 cell diameters) is believed to limit the risk of adverse side effects. Radium-223's half-life is 11.4 days. Its specific activity is 1.9 MBq (51.4 microcurie)/ng; molecular weight of 223RaCl2: 293.9 g/mol.[1][2][3]
Route: IV
Extravasation: no information
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
