4 Drug and Medication Information
4.1 Therapeutic Uses

POTASSIUM PERMANGANATE, USP, HAS LIMITED TOPICAL EFFICACY AGAINST BACTERIA & FUNGI. CONCN OF 1:5000 OR MORE ARE NECESSARY FOR EFFECTIVE BACTERICIDAL ACTION, BUT THEY ARE IRRITATING TO TISSUES. ... SOLN OF 1:10,000 ARE USUALLY USED. HOWEVER, UP TO AN HR MAY BE REQUIRED TO KILL ... BACTERIA & SOME ... SURVIVE EXPOSURE TO THIS CONCN. FOR THIS REASON, PERMANGANATE HAS BEEN MADE OBSOLETE BY /OTHER/ ... DRUGS. BECAUSE OF THE ASTRINGENCY OF MANGANOUS & MANGANIC IONS ... SUBSTANCE IS OCCASIONALLY USED TO SUPPRESS VESICULAR STAGE OF ECZEMA-DERMATITIS. A WET DRESSING OF PERMANGANATE MAY BE EMPLOYED IN THE TREATMENT OF IVY POISONING.

POTASSIUM PERMANGANATE IS EMPLOYED EXTERNALLY FOR GERMICIDAL, FUNGICIDAL, ASTRINGENT, OXIDIZING, & KERATOPLASTIC EFFECTS. SOLN ... SHOULD BE FRESHLY PREPARED.

American Hospital Formulary Service. Volumes I and II. Washington, DC: American Society of Hospital Pharmacists, to 1984., p. 84:04

4.2 Drug Warning

POTASSIUM PERMANGANATE (0.025%-0.1%) HAS ASTRINGENT PROPERTIES BUT STAINS SKIN. TABLETS SHOULD BE COMPLETELY DISSOLVED IF PLACED IN TUB OF WATER, BECAUSE ... CAN PRODUCE CUTANEOUS NECROSIS IF PATIENT INADVERTENTLY SITS ON THEM.

American Medical Association, Department of Drugs. Drug Evaluations. 6th ed. Chicago, Ill: American Medical Association, 1986., p. 1027


MOST BACTERIA ARE KILLED WITHIN 1 HR BY PERMANGANATES IN DILUTION OF 1:10,000, BUT SOME MICROORGANISMS SURVIVE EXPOSURE TO MUCH HIGHER CONCN. GERMICIDAL EFFICIENCY ... IS GREATLY REDUCED IN PRESENCE OF ORG MATTER. CONCN STRONGER THAN 1:5000 ARE IRRITATING TO TISSUES. POTASSIUM PERMANGANATE, USP, FORMS DEEP PURPLE SOLN, BUT IT LEAVES A BROWN STAIN ... /IN TREATMENT OF SNAKEBITE/ ... SOME BELIEVE THAT CMPD DOES MORE HARM THAN GOOD IN THE CRUST THAT IS FORMED, WHICH PRECLUDES POSSIBILITY OF SUCTION & DRAINAGE FROM WOUND.

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 998


Using potassium permanganate in "neutralizing" ingested nicotine, physostigmine, quinine, and strychnine is potentially dangerous. Potassium permanganate is a nephrotoxin and hepatotoxin, as well as a corrosive agent in the gastrointestinal tract. Aspiration can cause acute tracheobrochitis and bronchopneumonia. Fatty changes in the heart have been reported.

5 Pharmacology and Biochemistry
5.1 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.)

Adult channel catfish Ictalurus punctatus were exposed to waterborne potassium permanganate for 12 wk to determine if such exposure would alter the manganese content of axial muscle or liver tissue. Continuous exposure to 0.5 mg KMnO4 or exposure to 1 or 2 mg KMnO4/L on alternate days did not cause a significant incr in manganese in axial muscle or liver tissue. The mean (|SE) concn of manganese in axial muscle of unexposed controls was 0.262 | 0.018 mg/kg (wet weight). Means of scle could be detected within groups. The mean (|SE) concn of manganese in liver tissue of controls was 1.67 | 0.09 mg/kg (wet weight). Manganese concns in liver tissue of the three exposure groups were 1.57 | 0.07 mg/kg, 1.68 | 0.08 mg/kg, and 1.58 | 0.10 mg/kg, for 0.5 (continuous), 1, or 2 mg/L (alternate days), respectively. Manganese was thought to accumulate in liver tissue, however, there were no statistically significant differences between those groups & the controls.
