Pharmacological properties
Pharmacodynamics
Iodine is a vital trace element that is part of the thyroid hormones – thyroxine (T4) and triiodothyronine (T3), which ensures its normal functioning.
When iodides enter the epithelial cells of the thyroid follicles under the influence of the enzyme iodide peroxidase, iodine is oxidized to form elemental iodine. The substance undergoes a substitution reaction with the aromatic cycle of tyrosine, resulting in the formation of tyronines: 3,5-iodine derivative (hormone thyroxine – T4) and 3-iodine derivative (hormone triiodothyronine T3). Tyronines form a complex with the protein thyroglobulin, which is deposited in the colloid of the thyroid follicle and stored in this state for several days and weeks. With iodine deficiency, this process is disrupted. Iodine, which enters the body in physiological quantities, prevents the development of endemic goiter associated with a lack of this element in food; normalizes the size of the thyroid gland in newborns, children and adult patients of young age; affects the ratio of T3 / T4, the level of TSH.
Pharmacokinetics
After oral administration, iodine is almost completely absorbed in the small intestine. Within 2 hours after absorption, it is distributed in the intercellular space; accumulates in the thyroid gland, kidneys, stomach, mammary and salivary glands. The volume of distribution in a healthy person averages 23 liters (38% of body weight). The concentration in blood plasma after the application of a standard dose is 10-50 ng / ml, and the content of iodine in breast milk, saliva, gastric juice is 30 times higher than the concentration in blood plasma. The thyroid gland contains ¾ (10-20 mg) of all iodine in the body. Iodine is excreted mainly in the urine, to a lesser extent in the lungs and feces. When the equilibrium concentration is reached, the amount of iodine excreted is proportional to the daily intake with food.
