Nummit Topical Anesthetic Spray belongs to the group of local anaesthetics known as amide-type local anaesthetics. It is used to produce local numbness (anaesthesia). It works by reversibly block nerve transmission, when applied to a limited area of the body. Its active ingredient lidocaine bind to the sodium channels in the nerve membrane and prevent the entry of sodium ions in response to the membrane’s depolarization.
It is generally very safe, works quite quickly, and will reduce the discomfort. It can also be used as an anesthetic lubricant to insert instruments in the human body for medical procedures (e.g., catheters).
