A method for producing a radioactive arsenic-containing compound and a pharmaceutical composition containing the same are provided. (I) An arsenic-containing compound (the arsenic-containing compound is selected from the group consisting of As 2 O 3 , As 2 S 3 , As 2 S 2 and a combination thereof) is subjected to a neutron irradiation treatment. A method for producing a radioactive arsenic-containing compound, comprising the steps of: converting an arsenic element contained in the compound to a radioactive arsenic isotope; and (ii) recovering a product obtained from the step (i). Pharmaceutical compositions comprising a therapeutically effective amount of the radioactive arsenic-containing compound and a pharmaceutically acceptable carrier are formulated, for example, into injectable formulations and used in the treatment of tumors / cancers, such as hematological malignancies and solid tumors. Can be done. [Selection diagram] None |
