ATC Group: D08AG Iodine products

Iodine is an essential trace element in the human diet, necessary for the formation of thyroid hormones and consequently it is used in iodine deficiency and thyroid disorders. It also has antimicrobial activity.

For the prophylaxis and treatment of iodine deficiency disorders it may be given as potassium or sodium iodide, iodised oil, or potassium iodate. In the pre-operative management of hyperthyroidism iodine and iodides are used with antithyroid drugs such as carbimazole, thiamazole, or propylthiouracil.

Iodine has a powerful bactericidal action. It is also active against fungi, viruses, protozoa, cysts, and spores. Iodine is used as an antiseptic and disinfectant generally as a 2% or 2.5% solution.

Povidone iodine is an iodophore that has an established use as a broad-spectrum antiseptic, mainly for the treatment of contaminated wounds and for the preoperative preparation of the skin, mucous membranes and the ocular surface. The organic complex contains approximately 10% of active available iodine. Solutions of povidone iodine gradually release iodine to exert an antimicrobial effect against bacteria, fungi, viruses, and spores. Although povidone iodine is less potent than preparations containing free iodine, it is also less toxic.
