Potassium iodine

Potassium iodine tablets can be used to reduce radioactive iodine exposure to the thyroid gland. According to the National Council of Radiation Protection and Measurement (NCRP), taking 130 milligrams of potassium iodine at or before exposure to radioactive iodine effectively blocks nearly 100% of radioactive iodine from reaching the thyroid.1 Waiting 4 hours after exposure to take potassium iodine... 

Neonatal goiter caused by the use of potassium iodine as an expectorant during pregnancy has been reported (67). The neonate, a girl, had acute hypothyroidism, with myxedema and respiratory distress. She was given levothyroxine for 6 months, with complete normalization of thyroid function. 

Iodine is a germ-killer like chlorine and is also necessary for the health of the thyroid gland in humans. In fact, people who live close to nuclear power plants are often given emergency supplies of potassium iodine pills, in case the power plant has a leak of radioactive iodine. The pills flood the thyroid with normal iodine to keep the gland from absorbing the more harmful radioactive version of the element.

The main modification for practical use in endocrine safety pharmacology is the application of this method to satellite groups of animals in a repeated dose study. Most pelleted animal feeds nowadays contain a standard amount of iodine (it may be useful to check the specification). Therefore, the addition of potassium iodine to the drinking water is not required. In this satellite groups, the animals are injected with a standard dose of radio-iodine after the last treatment, and the dose of radioactivity accumulated in the thyroid glands after a standard time interval (e.g. two hours) is determined and evaluated. 

If the solution is titrated with standard sodium thiosulphate solution, the total concentration of the iodine, both as free I2 and combined as IJ, is obtained, since, as soon as some iodine is removed by interaction with the thiosulphate, a fresh amount of iodine is liberated from the tri-iodide in order to maintain the equilibrium. If, however, the solution is shaken with carbon tetrachloride, in which iodine alone is appreciably soluble, then the iodine in the organic layer is in equilibrium with the free iodine in the aqueous solution. By determining the concentration of the iodine in the carbon tetrachloride solution, the concentration of the free iodine in the aqueous solution can be calculated from the known distribution coefficient, and therefrom the total concentration of the free iodine present at equilibrium. Subtracting this from the total iodine, the concentration of the combined iodine (as Ij) is obtained by subtracting the latter value from the initial concentration of potassium iodine the concentration of the free KI is deduced. The equilibrium constant ...

In Inorganic Chemistry, typical spray reagents for cations include potassium iodine (0.2%, aqueous), hydrogen sulphide (saturated aqueous solution), ammonium sulphide (0.2 N, aqueous), quercetin (0.1%, alcoholic), l-(2-pyridylazo)-2-naphthol (PAN) (0.2%, methanolic), oxine (8-hydroxyquinoline) (1% methanolic, view under visible and UV light), and sodium rhodizonate (0.5%, aqueous). Reaction with dithizone to produce coloured dithizonate chelates of many metals is particularly suitable if quantitative spectrometric analysis (in situ or after elution) is to be carried out. Anions are detected with bromocresol purple (0.1%, alcoholic), 1% ammoniacal silver nitrate + 0.1% alcoholic fluorescein/UV light, zirconium alizarin lake (0.1% in HC1 solution), and ammonium molybdate (1%, aqueous) followed by SnCl2 (1%) and HC1 (10%). Typical detection limits range from 10 ng (10 9g) to several pg (10 6g).

What other kinds of supplements should be given Iodine supplements may be given in the form of potassium iodine or iodine-containing multivitamin pills especially designed for pregnancy purposes. The amount of iodine present should be expressed in micrograms. The only iodine compounds permitted are potassium iodide, potassium iodate, sodium iodide and sodium iodate. 

Prevention of hypothyroxinemia requires correct iodine intake. Different approaches exist, such as consumption of iodized salt — administration of potassium iodine and multivitamin pills containing iodine could also be considered, especially when restriction of salt consumption is recommended. 

Topical Application Substances with a saturated solution of potassium iodine are used for topical application to skin or mucosal surfaces. IIH has been repeatedly mentioned in case reports, when iodine-containing disinfections were applied to open wounds or for intraperitoneal lavage (Mumenthaler and Aeberhard, 1982 Share and Frey, 1980).

This process can be used when no chlorite is present in the range from 0.1 to approximately 0.002 mg/1 CIO2, using a 5-cm cuvette. Chlorine must first be eliminated with potassium bromide and sodium formate. In order to remove chlorine, 1.5 ml double-distilled water and 0.5 ml KBr solution are added to 50 ml of the water to be analyzed after 1 min. 0.5 ml sodium formate solution is added and allowed to stand for 15 mins. If no chlorine is present, 2.5 ml double-distilled water is simply added to the water to be analyzed. Approximately 3 drops of sulphuric acid are added in order to adjust to pH 2.5 with the aid of a pH meter. Then, 0.5 ml potassium iodine solution is added and mixed. The extinction is subsequently measured at 350 nm against a reference solution (52.5 ml double-distilled water, adjustment with approximately 3 drops H2SOz to pH 2.5 + 0.5 ml potassium iodide solution), using a 5-cm cuvette. The concentration of CIO2 is read off from the calibration curve.
