Description
Menthol is a covalent organic compound made synthetically or obtained from peppermint or other mint oils.
Forming clear or white waxy, crystalline substance, menthol is typically solid at room temperature. (-)-Menthol is the naturally-occurring and main form of menthol, and is assigned the (1R,2S,5R) configuration.
Menthol mediates anesthetic properties and anti-irritating properties locally, thus it is widely used to relieve minor throat irritations.
Indications
Used to treat occasional minor irritation, pain, sore mouth, and sore throat as well as cough associated with a cold or inhaled irritants.
Pharmacodynamics
Menthol is a covalent organic compound made synthetically or obtained from peppermint or other mint oils.
Menthol induces a cooling sensation on the skin upon inhalation, oral ingestion, or topical application by stimulating the cold-sensitive receptors expressed on the skin, without actually causing a drop in the skin temperature.
Mechanism of Action
Menthol primarily activates the cold-sensitive
TRPM8 receptors in the skin.
Menthol, after topical application, causes a feeling of coolness due to stimulation of'cold'receptors by inhibiting Ca++ currents of neuronal membranes.
It may also yield analgesic properties via kappa-opioid receptor agonism.
