Iodine-125 electrons from the radioisotope have been found in one study to do little cellular damage, unless the radionuclide is incorporated chemically directly into cellular DNA, which is not the case for present radiopharmaceuticals which use I-125 as the radioactive label nuclide. As with other radioisotopes of iodine, iodine-125 uptake in the body (mostly to the thyroid) can be blocked with prompt administration of stable iodine-127 in the form of an iodide or iodate salt. Potassium iodide (KI) is typically used for this purpose. Iodine-125 Iodine-125 (I) is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging
Cadexomer iodine populations have shown no sign of developing a resistance to iodine since it was first used for wound treatment in the middle of the 19th century. In addition to other manufacturers, Smith & Nephew distributes cadexomer iodine as Iodosorb and Iodoflex in many countries of the world for the treatment and healing of various types of wounds. The dosage forms are a paste dressing, an ointment and a gel, all of which contain 0.9% iodine. Cadexomer iodine Cadexomer iodine is an iodophor that is produced by the reaction of dextrin with epichlorhydrin coupled with ion-exchange groups and iodine. It is
