tetracain

Tetracaine is a potent local anesthetic of the ester group. It is mainly used topically in ophthalmology and as an antipruritic, and it has been used in spinal anesthesia. 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.

Tetracaine hydrochloride is a highly effective local anesthetic that can reversibly block nerve function. Tetracaine hcl used as a local anesthetic. Tetracaine hydrochloride can be used for topical anesthesia, and 0.05%-0.1% tetra caine hydrochloride can provide long-term and good effect of surface anesthesia. Meanwhile, tet racaine hydrochloride is still widely used in ophthalmic surface anesthesia, which has a long time for surface anesthesia and sensory resistance.
