Local anesthetics are stereospecific. Their action is dependent on the conformational state of the Na+ channel. Local anesthetics ability to bind to sodium channels is known as a state-dependent blockā. Local anesthetics bind more readily to the Na+ channel during depolarization (when it is open or activated).
