Menthol
Menthol (from lat. Mentha – mint) is an organic substance, an important secondary metabolite of plants of the Lamiaceae family, obtained synthetically or isolated from mint essential oil. It has weak local anesthetic properties, stimulates cold receptors of the skin and mucous membranes, a weak antiseptic. It is widely used in the food industry and in medicine. In particular, validol is the main component of the reflex vasodilator.
Physical and chemical properties
Transparent crystalline substance, melts easily at room temperature. Prismatic or needle-shaped, colorless or white lustrous crystals with a characteristic fresh, minty odour. Melting point: 42.5°C There are 8 isomers with fairly similar properties.
Security
Menthol has low toxicity, but should not be used in the first trimester of pregnancy. Direct contact of the pure substance with the skin may cause allergic reactions.
Pharmacological properties
In humans, menthol is metabolized to menthol glucuronide, in the urine the concentration of menthol glucuronide reaches 65-68% of the total absorbed menthol. Other less significant metabolites are hydroxyl menthol glucuronide, dihydroxy menthol glucuronide, menthol sulfoconjugate, as well as menthol aldehyde-hydroxyl glucuronide or menthol dialdehyde glucuronide in very low concentrations. The half-life of menthol averages 1.34 hours, sometimes slightly longer, with a range of 0.42–5.84 hours. The concentration in the blood and Tmax of menthol vary quite widely, glucuronidation, the main reaction of the II phase of metabolism, predominates. Menthol inhibits calcium channels at IC50s of 7.7-28.1mcg/mL (gut cells), 17.2-26.6mcg/mL (retinal cells) and 10.1-68.5mcg/mL (heart cells) and is twice as potent as the oil itself peppermint (IC50 concentration in retinal cells is 20.3-41.7 µg/ml). Menthol has a greater effect on intestinal cells than on heart and nerve cells; in terms of its effect, it can compete with nitrendipine, a calcium channel blocker. Menthol is a calcium channel antagonist with the same binding sites as nitrendipine.
Clinical
Menthol, when applied to mucous membranes or rubbed into the skin, irritates the nerve endings, causing a sensation of cold and tingling. When the cold receptors are excited, the superficial vessels constrict and the vessels of the internal organs reflexively expand. This explains the relief of pain under the action of menthol in angina pectoris (coronary vessels expand reflexively).
Menthol is also used for pain in the heart area. It is prescribed for disorders of the gastrointestinal tract, spastic colitis and enterocolitis, as an antiseptic and analgesic. It has a mild local anesthetic effect. Irritating the receptors of the mucous membrane of the stomach and intestines, menthol enhances peristalsis.
Menthol is part of Zelenin drops; is produced in the form of a powder, 1-2% menthol oil, 1-2% alcohol solution of menthol and menthol pencil, which includes 1.0 menthol, 3.5 paraffin and 0.5 caeserin. Rub the whiskey with a menthol pencil for migraines and headaches.
Menthol and peppermint oil are used for runny nose, colds, flu; these substances have been used in the Ingacamf inhaler.
With angina pectoris, Validol is taken – a solution of menthol in methyl ester of isovaleric acid.
Pure menthol in the form of various alcohol (menovazin) and water preparations is used in the complex treatment of eczema, dermatitis, neurodermatitis, urticaria, pruritus.
Validol – 25-30% solution of menthol in methyl ester of isovaleric acid.
Zelenin drops consist of 0.2 parts of menthol. The tooth drops contain 3.1 parts of peppermint oil. Boromenthol (ointment) includes 0.5 parts of menthol. Also, menthol is part of such drugs as pectusin, menovazin, equatol, camphomen, ingacamf (pocket inhaler), Efkamon ointment, which is used for arthritis, myositis and neuralgia.
