Potassium hydroxide, also known as lye is an inorganic compound with the chemical formula KOH. Also commonly referred to as caustic potash, it is a potent base that is marketed in several forms including pellets, flakes, and powders. It is used in various chemical, industrial and manufacturing applications. Potassium hydroxide is also a precursor to other potassium compounds. Potassium hydroxide is used in food to adjust pH, as a stabilizer, and as a thickening agent. This ingredient has been considered as generally safe as a direct human food ingredient by the FDA, based upon the observance of several good manufacturing practice conditions of use. In addition to the above uses, potassium hydroxide is also used in making soap, as an electrolyte in alkaline batteries and in electroplating, lithography, and paint and varnish removers. Liquid drain cleaners contain 25 to 36% of potassium hydroxide. Medically, potassium hydroxide (KOH) is widely used in the wet mount preparation of various clinical specimens for microscopic visualization of fungi and fungal elements in skin, hair, nails, and even vaginal secretions,. Recently, it has been studied for efficacy and tolerability in the treatment of warts. It was determined that topical KOH solution was found to be a safe and effective treatment of plane warts.

4 Drug and Medication Information
4.1 Therapeutic Uses

/EXP THER/ The effects of 1% potassium hydroxide aqueous solution and aqueous Teepol, a surfactant, on reducing subsequent development of anthralin inflammation without loss of therapeutic effect are described. Both compounds were effective and the action seemed to have resulted from enhanced oxidation of anthralin to inactive products by potassium hydroxide and from increased solubility and removal of anthralin by Teepol.

Lawrence CM et al; Br. J. Dermatol.; 116 ISS P171-177 (1987)


/EXP THER/ Potassium hydroxide (KOH) is a strong alkali that has long been known to digest proteins, lipids, and most other epithelial debris of skin scrapings to identify fungal infections. To our knowledge, KOH has never been used for the treatment of molluscum contagiosum (MC). We evaluated 35 children with MC for the clinical effectiveness of treatment with topical 10% KOH aqueous solution. The solution was applied by the parents of affected children, twice daily, on each MC lesion. The therapy was continued until all lesions underwent inflammation and superficial ulceration. Thirty-two of 35 patients achieved complete clinical cure after a mean treatment period of 30 days. Three children discontinued treatment: two reported severe stinging of the lesions and refused further applications; the other, with giant MC lesions, developed a secondary infection with prolonged treatment. Therapy with KOH was found to be effective and safe in the treatment of MC in children.

4.2 Drug Indication

Medically, the microscopic examination of potassium hydroxide (KOH) preparations is utilized in the diagnosis of fungal hyphae or trichomonads. Samples from hair, skin, or nail tissue are obtained by scraping with a scalpel, cotton-tipped applicator and are inoculated directly onto the KOH solution. In addition to the above, potassium hydroxide is used as a softener for nail grooves.


5 Pharmacology and Biochemistry
5.1 Pharmacology

The corrosiveness of potassium hydroxide renders it a very useful agent in the decomposition/removal soft tissue and hair removal. It is incorporated into some nail products, shaving creams, and soaps.


5.2 MeSH Pharmacological Classification

Indicators and Reagents

Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)


5.3 Absorption, Distribution and Excretion

Absorption

KOH in aqueous solutions completely dissociates into K+ and OH- ions. Because of the neutralization of OH- by gastric HCl and the rapid blood pH regulation action (buffer capacity of extracellular body fluids, respiratory and renal compensation mechanisms), an alkalosis due to the OH- ions after KOH oral dosage in non-irritating conditions is thus prevented. The uptake of potassium, in potassium hydroxide form, is much less than the oral uptake with therapeutic doses of KCl for treating potassium deficiency, of up to 10 g/day. Furthermore, the oral uptake of potassium from food/natural sources or from food additives is likely to be also much higher.


Interesting observations are also that alkalosis promotes renal excretion of K+, and that, for preventing hyperkalemia, extra cellular potassium is taken up by cells in exchange for hydrogen ions (Saxena, 1989). In other words, these compensating effects of K+ and OH- would attenuate the systemic effect of KOH.

...It can also be stated that the substance will neither reach the foetus nor reach male and female reproductive organs in effective toxic concentrations. Therefore, no risk for reproductive toxicity is expected.

Under normal handling and use conditions (non-irritating) neither the concentration of potassium in the blood nor the pH of the blood will be increased above normal limits and therefore KOH is not expected to cause systemically toxic levels in the blood. The renal excretion of K+ can be elevated and the OH- ion is neutralised by the bicarbonate buffer system in the blood...

5.4 Metabolism/Metabolites

KOH in aqueous solution is entirely dissociated into K+ and OH- ions. Due to the neutralization of OH- by gastric HCl and the quick and efficient blood pH regulation mechanisms (buffer capacity of extra cellular body fluids, respiratory and renal compensation mechanisms), an alkalosis due to the OH- ions after KOH oral dosage in non-irritating conditions is prevented.

...In every case, it should be realised that aerosols of KOH are not stable.

5.5 Mechanism of Action

The exact mechanism of action of KOH is not known but the speculated one is that topical application of KOH digests keratin, and induces inflammation. The mechanism of skin injury by alkali substances such as potassium hydroxide is by the saponification of fat, causing fatty tissue to lose its function with increased damage due to a heat reaction. Extraction of water from cells occurs due to the hygroscopic (absorbent) nature of alkali. Dissolution of proteins also occurs, allowing for deeper penetration of OH- ions and resulting in various chemical reactions. The alkali penetrates the skin quickly, saponifies plasma membranes, denatures collagen proteins, and leads to vascular thromboses in the conjunctiva and other parts of the eye. The resulting corneal burns include scarring and opacification of the cornea with resulting in vision loss, corneal neovascularization, ulcer formation, and perforation. Other consequences of untreated or very severe alkali burns include epithelial erosions, secondary glaucoma, and causes the destruction of conjunctival mucus cells, causing dry eyes, trichiasis (misdirected eyelash hairs), and other ocular conditions. In the gastrointestinal tract, after oral ingestion, burns may result. The mechanism of injury is liquefactive necrosis. The thrombosis of gastrointestinal blood vessels also contributes to tissue damage. When the alkali enters the stomach, gastric acid may neutralize the strong base, which can limit the extent of the injury. Perforation of the stomach can sometimes occur with peritonitis and caustic injury to the surrounding organs including the colon, pancreas, liver, and spleen.


The mechanism of injury by alkali skin burns is by saponification of fat, which causes fatty tissue to lose its function with increased damage due to heat reaction; extraction of considerable water from cells due to the hygroscopic nature of alkali; and dissolution of proteins, permitting so deeper penetration of OH- ions and further chemical reactions.

A systemic (non-acute) oral intoxication by KOH is not expected. Regarding the potassium toxicity, the LD50 value in rats of KCl, 3.020 g/kg bw/day is much higher than that of KOH, in the range of 0.273 - 0.365 - 1.230 g KOH/kg bw/day. This demonstrates that the acute toxicity of KOH is probably due to the corrosivity caused by the OH- ion (pH value), and less to systemic toxic effects of the K+ ion. Under non-irritating conditions, the potassium doses are much lower than those used in acute toxicity studies, and therefore not relevant from the point of view of the systemic toxicity of potassium. Furthermore, the uptake of potassium, via exposure to potassium hydroxide, is much less than the oral uptake with therapeutic doses of KCl for treating potassium deficiency, of up to 10 g/day. Moreover, the oral uptake of potassium from food, from natural origin or from food additives, is likely to be also much higher.
