Questions asked by users might not always be phrased in the clearest way.
Briefly state the mechanism of action of benzocaine in vivo?
Accepted Answer
Benzocaine acts as a local anesthetic by blocking the transmission of pain signals through nerve fibers. It does this by reversibly binding to the sodium channels in the nerve cell membrane, inhibiting the influx of sodium ions. This disruption of sodium ion transport prevents the generation and propagation of action potentials, effectively blocking the transmission of pain signals to the brain.
