Description

Radium Ra 223 dichloride is a radiotherapeutic drug that is approved for the treatment of male patients with symptoms of advanced prostate cancer with bone metastases. Ra 223 mimics calcium and forms complexes with the bone mineral hydroxyapatite at areas of increased bone turnover. The radioactive alpha particles emitted by radium Ra 223 helps in killing cancer cells in the bone by damaging their DNA. Radium Ra 223 causes minimal damage to the nearby healthy cells.
