Lidocaine

Lidocaine is a local anesthetic and antiarrhythmic medication used to temporarily numb or block sensations of pain in a specific area of the body. It works by inhibiting nerve signals in the affected region, preventing the transmission of pain impulses to the brain. Lidocaine is frequently used for minor medical procedures, dental work, and various dermatological treatments. Additionally, in its antiarrhythmic form, lidocaine can help regulate abnormal heart rhythms by affecting the electrical activity of the heart. It is available in various forms such as creams, ointments, sprays, and injections.
