Iodine is one of the most widely used elements both domestically and industrially. A French physician was the person to ever use lugols iodine solution in the year 1829. He prepared it by mixing elemental iodine with potassium iodide and dissolving in water. Today, the resultant compound is widely used in domestic and industrial application. Its use has been especially appreciated in scientific research. It is also known by other terms such as Markodine, iodine potassium iodide and Strong solution.
Markodine is available as an over the counter formulations such as gels, tinctures and ointments. These formulations are mainly designed for topical use where there is a need to disinfect minor skin injuries. It is common to mix the iodine with another ingredient known as povidone so as to increase the effectiveness. Another major application is the use in disinfection of water especially in emergency situation.
Lugols has a characteristic reaction in the presence of starch which is widely available in many organic compounds. When it interacts with the polysaccharides that make up starch molecules there is a blue black colour change and this is considered a positive reaction. For this reason, the solution is used in a number of biochemical experiments. The same reaction is seen when testing for a condition known as amyloidosis in living cells.
The compound is important in management of some types of cancers particularly cervical cancer. In this test, the solution is used to stain the entire cervix and part of the upper vagina. Normal tissues take the whole stain and appear dark brown when examined under a colposcope. The abnormal tissues do not stain entirely and appear paler. The pathologist selects these areas for taking of biopsies.
Markodine is used in the management of selected patients with Graves disease as they undergo surgery (thyroidectomy). Graves disease is a severe form of hyperthyroidism. It has been established through research that when administered intraoperatively, the solution reduces the amount of blood loss. This benefit may not be seen in patients whose thyroid function is normal or those that are on antithyroid medication.
For many years, Lugols was used in the treatment of gout. With the advent of newer and more effective therapies, it is no longer used as commonly. In the treatment of hyperthyroidism it was considered a first line therapy but has been dropped over time due to the side effect of inhibiting thyroid hormone effect (also known as Wolff Chaikoff effect). This often leads to hypothyroidism.
Macroalgae require elemental iodine for growth and survival. The element is also important for other coral reef inhabitants. For these reasons, it is heavily used in the maintenance of marine ecosystems. Its effects are mainly due to its ability to significantly reduce the number of harmful bacteria and parasites. The other major benefits are the prevention of coral reef bleaching and polyp expansion.
When used in excess, the compound may have some unwanted effects on the body. At low dilutions, it is said to have an irritating and corrosive effect on the stomach mucosa. This may be encountered when conducting endoscopic examinations. Generally, however, it is regarded as being safe.
