Tetracaine is an ester-type local anesthetic used primarily for topical anesthesia of the eye, nose, and throat, and occasionally for spinal anesthesia. It acts as a sodium channel blocker, preventing nerve impulse conduction. It is approved and still used clinically, especially as a topical and spinal anesthetic.
Pharmacokinetics
Estimated pharmacokinetic parameters based on general properties of ester-type local anesthetics. No specific published human PK studies found for tetracaine.
