Menthol + Pramoxine Hydrochloride

Pain and Itching: For temporary relief of pain and itch associated with minor skin irritations, minor cuts, minor burns, minor sunburns, scrapes, or insect bites; may also be used for rashes due to poison ivy, oak, or sumac.

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.

Pramocaine reversibly binds and inhibits voltage gated sodium channels on neurons decreasing sodium permeability into the cell. This stabilizes the membrane and prevents ionic fluctuations needed for depolarization stopping any action potential propagation.

Menthol and pramoxine: Each of these agents elicits local anesthetic effects.
