Tetracaine HCL, is a local anesthetic drug and an ester derivative of p-amino benzoic acid. It acts by interfering with the entry of sodium ions into nerve cells and is one of the commonly used topical anesthetics.
Tetracaine HCL is a local anesthetic used topically in opthalmology.It is a highly effective local anesthetic that reversibly blocks nerve function. It is clinically used for infiltration anesthesia, nerve block anesthesia, epidural anesthesia, etc. Compared with p rocaine, its local anesthesia effect is remarkable. T etracaine hydrochloride has been widely used in clinical practice. In biomedical research, tetracaine is used to alter the function of calcium release channels (ryanodine receptors) that control the release of calcium from intracellular stores. Tetracaine is an allosteric blocker of channel function. At low concentrations, tetracaine causes an initial inhibition of spontaneous calcium release events, while at high concentrations, tetracaine blocks release completely.
