Pharmacological properties

ATC Vet Code: QD 08AG03

5.1 Pharmacodynamic properties

Iodine has a powerful bactericidal action. It is also active against fungi, viruses, protozoa, cysts and spores. Iodine is used as a disinfectant generally as a 2% or 2.5% solution. Its activity is reduced in the presence of organic matter, though not to the same extent as with other halogen disinfectants. A solution of iodine may be applied to small wounds or abrasions as well as to unbroken skin, but an iodophor such as povidone iodine may be preferred.

5.2 Pharmacokinetic properties

Iodine is an essential trace element in the human diet, it is necessary for the formation of thyroid hormones. It is used for the prophylaxis and treatment of iodine deficiency disorders such as endemic goitre, in areas where the diet is deficient in iodine. It may be administered as potassium or sodium iodate.

Iodine is slightly absorbed when applied to the skin. When taken by mouth, iodine preparations (which are converted to iodide) and iodides are trapped by the thyroid gland. Solutions of iodine applied to the skin should not be covered by occlusive dressings.

Iodides not taken up by the thyroid are excreted mainly in the urine, with smaller amounts appearing in the faeces, saliva and sweat. They cross the placenta and are excreted in breast milk.

Iodine and iodides, whether applied topically or administered systemically, can also give rise to hypersensitivity reactions which may include urticaria, angioedema, cutaneous haemorrhage or purpuras, fever, arthralgia, lymphadenopathy and eosinophilia.
