Menthol has local anesthetic and counterirritant qualities, and it also acts as a weak kappa (κ) opioid receptor agonist. Menthol acts to chemically trigger the cold-sensitive TRPM-8 receptors in the skin — responsible for the well-known cooling sensation it stimulates when applied directly to the skin. Menthol’s analgesic properties are not fully understood, however they are mediated through a selective activation of κ-opioid receptors. Menthol also blocks voltage-sensitive sodium channels, reducing neural activity that may stimulate muscle tissue.
Lidocaine is a topical anesthetic and stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action.

INDICATIONS AND USE:
K2K Patch® is a formulation used to aid patients in the pharmaceutical management of topical mild to moderate acute or chronic aches or pain. Muscle or joint pain can stem from many disease states — musculoligamentous strains, simple backache, tendonitis, osteoarthritis, rheumatoid arthritis, peripheral neuropathies, such as diabetic neuropathy, post herpetic neuralgia, and other complex regional pains.
This patch has also been used as adjunct therapy to certain types of headaches, but it is advised to use with caution when applying in order to avoid eye contact. If instructed otherwise by your practitioner, it may be used for other conditions as well.
Because of the possibility of sedation, patients should be cautioned regarding the operation of serious machinery or automobiles, and activities made hazardous by decreased alertness.
Known hypersensitivity to menthol, lidocaine, or any of the topical amide-like anesthetic preparations. .

- Serious adverse experiences following the administration of K2K Patch® are similar in nature to those observed in other amide anesthetic-containing agents. These adverse experiences are, in general, dose-related and may result from high plasma levels caused by excessive dosage, rapid absorption, or may result from hypersensitivity, idiosyncrasy, or a diminished tolerance on the part of the patient. Serious adverse experiences are generally systemic in nature.

What constitutes K2K Patch ® ?
This is a topical patch consisting of the topical anesthetic lidocaine and the analgesic, menthol.
Why was K2K Patch ® prescribed by my doctor ?
When unwrapped and accurately placed against the skin, the patch is applied to the skin and greatly assists sufferers in the management of mild to moderate topical acute aches or pains.
We are not concerned simply with the masking of serious pain triggers. The experiencing of acute or chronic topical pain is a reflection and the body’s method of telling you that something (potentially serious, potentially causing long term damage) needs attention. If the cause of recurrent pain is identified, the pain needs to be assessed by the appropriate healthcare professional, and a diagnosis made. This root cause diagnosis will dictate the course of treatment.
Lidocaine and menthol have been used separately for centuries to reap the pain relieving and numbing effects, however we have created a combination of the two that is absorbed through the dermal layer of the skin and instantly has a positive effect on the topical pain. The combination of these two ingredients is a highly effective combination that work together to lessen the discomfort, while the root cause is being managed and treated by your healthcare team.
