1. A process for manufacturing a pharmaceutical aqueous solution, the process comprising diluting an aqueous complex solution with an aqueous dilution solution to form the pharmaceutical aqueous solution;
wherein the aqueous complex solution comprises: (a) a complex comprising (ai) the radionuclide 177Lu (Lutetium-177) and (aii) a somatostatin receptor binding peptide linked to the chelating agent DOTA, and (b) at least one stabilizer(s) against radiolytic degradation that is/are present in a total concentration of 15 mg/mL to 50 mg/mL in the aqueous complex solution; and
wherein the aqueous dilution solution comprises at least one stabilizer(s) against radiolytic degradation; and
wherein the radionuclide is present in the pharmaceutical aqueous solution in a concentration that provides a volumetric radioactivity of 250 to 500 MBq/mL, and the stabilizer(s) against radiolytic degradation is/are present in the pharmaceutical aqueous solution in a total concentration of 0.5 mg/mL to 10.0 mg/mL; and
the pharmaceutical aqueous solution comprises less than 1% ethanol.
