It is bactericidal, sporicidal, protozoacidal, cysticidal, and virucidal. Liquid formulations of iodine are usually prepared in ethanol (tincture of iodine) to increase solubility and concentration. Lugol solution is 5% iodine and 10% iodide in water. Iodoform is triiodomethane (CHI3). Iodophors such as povidone-iodine (Betadine) consist of iodine linked to a large–molecular-weight molecule. These are usually less toxic owing to the slow release of iodine from the carrier molecule. Radioactive iodine is used in the treatment of thyroid cancer. The antiarrhythmic drug amiodarone releases iodine and may cause either thyrotoxicosis or hypothyroidism after prolonged use. Iodine is also used in the manufacture of dyes and photographic reagents. Table salt is fortified with iodine.
