Abstract
A method for producing a radiopharmaceutical, the method capable of maintaining a radioactive compound retaining a chemical structure and radioactivity at the time of production and after the production, and maintaining a usable period of a radiopharmaceutical; and a radiopharmaceutical are provided. The method for producing a radiopharmaceutical that has a radioactive component containing a radioactive dithiosemicarbazone copper complex includes: a stabilization step of adding a stabilizing agent containing at least one compound selected from the group consisting of ascorbic acid, methionine, sodium ascorbate, mannitol, and butylhydroxyanisole to a solution containing the radioactive component; and a filtration step of filtering the solution containing the radioactive component or a precursor thereof with a sterilization filter. In the radiopharmaceutical, a concentration of the radioactive component is 200 MBq/mL or more in terms of radioactivity concentrations.
