The present invention relates to radionuclide complex solutions of high concentration and of high chemical stability, that allows their use as drug product for diagnostic and/or therapeutic purposes. The stability of the drug product is achieved by at least one stabilizer against radiolytic degradation. The use of two stabilizers introduced during the manufacturing process at different stages was found to be of particular advantage.本發明涉及高濃度的以及高化學穩定性的放射性核種錯合物溶液，所述性質使所述放射性核種錯合物溶液能夠用作診斷和/或治療目的的藥物產品。藉由至少一種抗放射性分解降解的穩定劑實現藥物產品的穩定性。發現在製造方法期間在不同階段引入的兩種穩定劑的使用係特別有利的。
