[The pentasodium salt of samarium Sm 135 lexidronam, a therapeutic agent consisting of a medium energy beta- and gamma-emitting radioisotope, samarium Sm 135, and a teraphosphonate chelator, ethylenediaminetetramethylene phosphonic acid (EDTMP). The chelator moiety of samarium Sm 153 lexidronam associates with hydroxyapatite crystals concentrated in areas of bone turnover, thereby selectively delivering samarium Sm 153-mediated cytotoxic radiation to osteoblastic bone metastases.
