IOTHIOURACIL, in a form of sodium salt, was used as an antithyroid agent in the treatment of hyperthyroidism. It is selectively incorporated into the melanin pigment of melanomas during biosynthesis by serving as false melanin precursors. Radiolabelled (125I) IOTHIOURACIL may be used as a radiopharmaceutical for diagnosis and therapy of melanotic melanomas.
