Abstract
The invention provides improved formulations of .sup.117m Sn (Sn.sup.4+) DTPA which allow higher doses of .sup.117m Sn (Sn.sup.4+) to be administered than were previously possible. Methods for making pharmaceutical compositions comprising .sup.117m Sn (Sn.sup.4+) DTPA in which the amount of unchelated DTPA is minimized are disclosed along with methods of using the improved formlulations, both for palliation of bone pain associated with cancer and for treatment of osseous tumors.
