[11] In the United States a course of treatment is less than US$25. [9] It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. Commercially available iobenguane is labeled with iodine-123, and product labeling recommends administration of potassium iodide 1 hour prior to administration of the radiopharmaceutical for all age groups,[16] while the European Association of Nuclear Medicine recommends (for iobenguane labeled with either isotope), that potassium iodide administration begin one day prior to radiopharmaceutical administration, and continue until the day following the injection, with the exception of new-borns, who do not require potassium iodide doses following radiopharmaceutical injection. [26], There have been some reports of potassium iodide treatment causing swelling of the parotid gland (one of the three glands that secrete saliva), due to its stimulatory effects on saliva production.[27]. what is the formula and give the name for the compounds formed from the following ions:? Potassium iodide is a chemical compound, medication, and dietary supplement. Washington DC: American Pharmacists Association; 2004. Provided below is a list of the chemical formulas of some common chemical compounds … The basic unit of ionic compounds is the formula unit. 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. [15][17], 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. "[20] Consequently, far more people than anticipated were affected by the radiation, which caused the United Nations to report in 2002 that "The number of people with thyroid cancer... has exceeded expectations. [46][47], As of 2020, potassium iodide tablets are made available free of charge for all residents in all pharmacies throughout the country. [12] Potassium iodate (KIO3) is used to add iodine to some salts so that the iodine is not lost by oxidation. 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;[29] 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.[30]. This is not the same as blocking the thyroid's release of thyroid hormone, for which the adult dose is different (and is actually higher by a factor of 7 or 8[citation needed]), and for which KI anti-radiation pills (not a common medical treatment form of KI) are not usually available in pharmacies, or normally used in hospitals, or by physicians. Potassium forms the cation of K+ and iodine the anion of I-. 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. It is a scavenger of hydroxyl radicals. The Swedish manufacturing facility for Thyrosafe, a half-strength potassium iodide tablet for thyroid protection from radiation, was mentioned on the secret US 2008 Critical Foreign Dependencies Initiative leaked by Wikileaks in 2010.[50]. More severe side effects that require notification of a physician are: fever, weakness, unusual tiredness, swelling in the neck or throat, mouth sores, skin rash, nausea, vomiting, stomach pains, irregular heartbeat, numbness or tingling of the hands or feet, or a metallic taste in the mouth. However, for several fluorophores addition of KI in μM-mM concentrations results in increase of fluorescence intensity, and iodide acts as fluorescence enhancer.[31]. What are the disadvantages of primary group? "[21] For optimal prevention, KI must be dosed daily until a risk of significant exposure to radioiodine by either inhalation or ingestion no longer exists. [10] Potassium iodide is available as a generic medication and over the counter. Bedford, MA: CIS-US, Inc. July 1999. [9] Some of the earliest uses included for syphilis.[9]. Why is melted paraffin was allowed to drop a certain height and not just rub over the skin? [36][37] 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. Relevance. Such radiation doses will not occur far away from an accident site. Hg2+ and S2-Answer Save. "[42], These findings were consistent with studies of the effects of previous radioactivity releases. Thus it is an ionic compound. Apply the rules for naming that type of compound. The measures were seen as precautions, and the Pentagon said no U.S. forces have shown signs of radiation poisoning. [11] Potassium iodide is also used for the iodization of salt. "[20], The U.S. Department of Health and Human Services restated these two years later as "The downward KI (potassium iodide) dose adjustment by age group, based on body size considerations, adheres to the principle of minimum effective dose. [citation needed], 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. Potassium iodide has been used medically since at least 1820.
