Abstract

Particle-emitting radionuclides, e.g. Gd-159, Ho-166, Lu-177 and Yb-175, have been complexed with organic aminoalkylenephosphonic acids wherein the nitrogen and phosphorus are interconnected by an alkylene group or substituted alkylene group. These complexes have been found useful in compositions for the therapeutic treatment of calcific tumors in animals and in relief of bone pain.
