Mechanism of action

Tetracaine reversibly binds to and blocks voltage-gated sodium channels on the inner surface of nerve cell membranes, preventing depolarization and action potential propagation. This results in local anesthesia of the cornea and surrounding ocular tissues when applied topically as an ophthalmic drop. The drug has a rapid onset and intermediate duration of action suitable for ocular procedures.
