Lidocaine is a local anesthetic and antiarrhythmic medication commonly used to numb tissues in a specific area or to treat certain types of abnormal heart rhythms. Its primary mechanism of action involves blocking voltage-gated sodium (Na⁺) channels on the neuronal cell membrane. Normally, during nerve signal transmission, sodium channels open, allowing Na⁺ ions to flow into the cell and initiate an action potential. Lidocaine binds to these sodium channels, particularly in their inactivated state, preventing them from opening. This blockade inhibits the influx of sodium ions, which disrupts the propagation of the action potential along the nerve fibers, ultimately stopping the sensation of pain. Because it preferentially binds to active and inactivated channels, lidocaine is especially effective in rapidly firing neurons, such as pain fibers and overactive cardiac cells. This selective action makes lidocaine useful not only in localized anesthesia but also in controlling abnormal heart rhythms by slowing electrical conduction in the heart. Which of the following best describes how lidocaine’s mechanism of action selectively disrupts nerve and cardiac signal transmission?
