Medicine Description lidocaine 10%
Lidocaine 10% Spray is a medication that acts as a local anesthetic, primarily by blocking sodium channels in the neuronal cell membranes. When lidocaine is applied topically, it penetrates the skin and mucous membranes to inhibit the influx of sodium ions during the phase of depolarization, which is critical for the generation and conduction of action potentials in nerve fibers. This disruption in nerve signal transmission effectively diminishes the sensation of pain in the targeted area, providing rapid and localized numbness. The lidocaine molecule's lipid solubility allows it to diffuse across nerve membranes, making it particularly effective for short-term pain relief in various applications.
