Abstract: The present disclosure concerns radiopharmaceutical compositions of radioactive halogenated benzylguanidine (such as radioiodinated MIBG) or a pharmaceutically acceptable salt, hydrate, or solvate thereof. In a preferred embodiment, the composition has at least 97% of radiochemical purity for at least 4 days. Advantageously, the compositions of the present disclosure may be devoid of parabens, which are carcinogenic and yet are used in known radioactive MIBG compositions. The present disclosure also provides processes of preparing a radioactive halogenated benzylguanidine composition. The compositions of the present disclosure can be used in diagnosis and treatment of various diseases.
