Pharmacological properties

Pharmacotherapeutic group:

ATC Vet Code:

QD08AG03

5.1 Pharmacodynamic properties

Iodine has a powerful 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 as teat disinfectants have a wide range of activity against mastitis causing bacteria.

5.2 Pharmacokinetic properties

Absorption:

When taken by mouth, iodine preparations (which are converted to iodide) and iodides are absorbed throughout the gastro-intestinal tract in man but mainly from the rumen in cattle. It accumulates in the thyroid gland and concentrates in gastric and salivary secretions. 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 are excreted mainly in the urine, with smaller amounts appearing in the faeces, saliva and milk.

Udder cloths should be allowed to soak in the solution. The use of separate udder cloths for each cow, or disposable paper towels is strongly recommended.

Adverse reactions

Iodophor teat disinfectants can be regarded as safe for the dairy cow when used as recommended. At the concentrations used for post milking teat sanitation (5000 ppm) their local and resorptive tolerance is good. In the rare case of a suspected proven allergy in the herd, it is recommended to change to an non-iodine teat disinfectant.
