Pharmacological properties

Pharmacotherapeutic group:

ATC Vet Code: QD 08AG03

5.1 Pharmacodynamic properties

Iodine has a powerful broad spectrum bactericidal action and is used for disinfecting unbroken skin before operation. It is also active against fungi, viruses, protozoa, cysts and spores. It is generally employed as a disinfectant for human skin application as a 2% or 2.5% solution of iodine . The germicidal activity is reduced in the presence of organic matter although the reduction is reported to be less than that observed with other halogen disinfectants.

Iodophors (such as the product) as teat disinfectants have a strong activity against a wide range of bacteria.

5.2 Pharmacokinetic properties

Absorption:

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

Distribution and Elimination:

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.
