Neither SSKI or KI tablets are used as nutritional supplements, since the nutritional requirement for iodine is only 150 micrograms (0.15 mg) of iodide per day. All of these doses should be compared with the far lower dose of iodine needed in normal nutrition, which is only 150 μg per day (150 micrograms, not milligrams). Noting that KI's effectiveness was "virtually complete" and finding that iodine in the form of KI was substantially superior to other forms including iodate (KIO3) in terms of safety, effectiveness, lack of side effects, and speed of onset, the FDA invited manufacturers to submit applications to produce and market KI. Potassium iodide is an ionic compound which is made of the following ions: K+I−. Bedford, MA: CIS-US, Inc. July 1999. Potassium iodide is also not recommended for people with dermatitis herpetiformis and hypocomplementemic vasculitis – conditions that are linked to a risk of iodine sensitivity. Potassium Iodide KI bulk & research qty manufacturer. Delen. Potassium iodide can be conveniently prepared as a saturated solution, abbreviated SSKI. In a small study on human subjects, who for each of their 90-day trial, ingested four 20 milligram tetraglycine hydroperiodide (TGHP) water tablets, with each tablet releasing 8 milligrams (ppm) of free titratable iodine; it was found that the biological uptake of radioactive iodine in these human subjects dropped to, and remained at, a value of less than 2% the radioiodine uptake rate of that observed in control subjects who went fully exposed to radioiodine without treatment..

By saturating the body with a source of stable iodide prior to exposure, inhaled or ingested 131I tends to be excreted, which prevents radioiodine uptake by the thyroid. Today, nearly half (44.8%) the survivors of Nagasaki studied have identifiable thyroid disease, with an editorial in The Journal of the American Medical Association reporting "it is remarkable that a biological effect from a single brief environmental exposure nearly 60 years in the past is still present and can be detected. Mobility in soil No additional information available 12.5. The alkali metal iodide salt, over time and exposure to excess oxygen and carbon dioxide, slowly oxidizes to metal carbonate and elemental iodine, which then evaporates. Typical reducing agent. . Dedicated nutritional iodide tablets containing 0.15 mg (150 micrograms (μg)) of iodide, from KI or from various other sources (such as kelp extract) are marketed as supplements, but they are not to be confused with the much higher pharmaceutical dose preparations.

As a supplement it is used in those who have low intake of iodine in the diet.  It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. It finds widespread application as an iodide source because it is less hygroscopic than sodium iodide, making it easier to work with.  For example: KI, acting as a source of iodide, may also act as a nucleophilic catalyst for the alkylation of alkyl chlorides, bromides, or mesylates. Potassium Iodide is a metal halide composed of potassium and iodide with thyroid protecting and expectorant properties. Stop taking medicine to subside. , In 1982, the U.S. Food and Drug Administration approved potassium iodide to protect thyroid glands from radioactive iodine involving accidents or fission emergencies.

The use of KI...was credited with permissible iodine content in 97% of the evacuees tested. Thyroid iodine uptake blockade with potassium iodide is used in nuclear medicine scintigraphy and therapy with some radioiodinated compounds that are not targeted to the thyroid, such as iobenguane (MIBG), which is used to image or treat neural tissue tumors, or iodinated fibrinogen, which is used in fibrinogen scans to investigate clotting. 0 0. However, KI administration 96 h or more before 131I exposure has no significant protective effect. It is used mainly in the form of a saturated solution, 100 g potassium iodide to 100 ml water. The temperature required to melt potassium iodide is high because it is an ionic compound held together by an ionic bond. , Product labeling for diagnostic iodine-131 iobenguane recommends potassium iodide administration one day before injection and continuing 5 to 7 days following administration, in keeping with the much longer half-life of this isotope and its greater danger to the thyroid.

Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. It can also cause sialadenitis (an inflammation of the salivary gland), gastrointestinal disturbances, and rashes. For SSKI, a solution more viscous than water, there are assumed to be 15 drops per mL; the iodide dose is therefore approximately 51 mg per drop. In all these cases however, despite the risks, the prophylaxis benefits of intervention with iodide, iodate or perchlorate outweigh the serious cancer risk from radioiodine bioaccumulation in regions where radioiodine has sufficiently contaminated the environment. With pure water, the concentration of KI in the solution depends only on the temperature. UNII-T66M6Y3KSA.

Melting point. in rats: 285 mg/kg (Hildebrandt), Potassium iodide However, adolescents approaching adult size (i.e., >70 kg [154 lbs]) should receive the full adult dose (130 mg) for maximal block of thyroid radioiodine uptake. Until drinking, the solution is normally applied to the tea, fruit juice or milk. KI can turn yellow upon heating in air or upon standing in moist air for long periods, because of oxidation of the iodide to iodine. It can occur immediately after taking the drug, or an angioedema may occur several hours later. Unlike I2, I3− salts can be highly water-soluble. ... Melting point/Melting range: 681 °C (1258 °F) Boiling point/Boiling range: 1330 °C (2426 °F) Sublimation temperature / start: Not determined Flammability (solid, gaseous) Adding a heat will convert the solid into a liquid with no temperature change. Potassium iodide can block absorption of radioactive iodine by the thyroid gland through flooding the thyroid with non-radioactive iodine and preventing intake of radioactive molecules, thereby protecting the thyroid from cancer causing radiation. , The potassium iodide in iodized salt is insufficient for this use. In accordance with the column 2 of Annex VII of the REACH regulation, this end point can be considered for waiver since the melting point is above 300 C. However, there is data which indicates that the vapour pressure of potassium iodide is 133.322 Pascal at temperature of 745oC. 7790-42-3.

Of these products, 131I (Iodine-131) is one of the most common and is particularly dangerous to the thyroid gland because it may lead to thyroid cancer. KI is a component in some disinfectants and hair treatment chemicals. It is produced industrially by treating KOH with iodine.. LS-118370. to the dried substance), Potassium iodide, Puratronic?, 99.998% (metals basis). Potassium iodide is a chemical compound, medication, and dietary supplement. LS-118370. Thus, the spectrum is structurally similar to those found in … According to one 2000 study "KI administered up to 48 h before 131I exposure can almost completely block thyroid uptake and therefore greatly reduce the thyroid absorbed dose. Aqueous KI3, "Lugol's solution", is used as a disinfectant and as an etchant for gold surfaces. Long-term use may cause oral, throat burning sensation, runny nose, metallic taste, tooth and gum pain, stomach discomfort, severe headache and other symptoms of iodine poisoning; hyperkalemia symptoms such as confusion, arrhythmia, numb and tingling feeling in hands and feet, and weakness of lower limbs may also occur. The key difference between iodine and potassium iodide is that iodine is a chemical element whereas potassium iodide is a chemical compound.. Iodine is a halogen that locates in group 17 of the periodic table of elements.On the other hand, potassium iodide is a chemical compound that forms from the combination of iodine and potassium. , There is reason for caution with prescribing the ingestion of high doses of potassium iodide and iodate, as their unnecessary use can cause conditions such as the Jod-Basedow phenomena, trigger and/or worsen hyperthyroidism and hypothyroidism, and then cause temporary or even permanent thyroid conditions.
