Pharmaceutical Grade Local Anesthetic Powder CAS 136-47-0 Tetracaine HCl Powder

Pharmaceutical Raw Material Tetracaine HCl ​​​​​​​ Product Name Tetracaine HCl Alias Amethocaine CAS 136-47-0 MF C15H25ClN2O2 MW 300.82 Assay 99% Grade Pharmaceutical Grade Appearance White Powder Description Tetracaine HCl is synthesized from 4-butylaminobenzoic acid. The ethyl ester is formed through an acid-catalyzed esterification reaction. Base-catalyzed transesterification is achieved by boiling the ethyl ester of 4-butylaminobenzoic acid with excess 2-dimethylaminoethanol in the presence of a small amount of sodium ethoxide. Tetracaine (INN, also known as amethocaine; trade name Pontocaine. Ametop and Dicaine) 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. Application Tetracaine hcl is indicated for the production of spinal anesthesia for procedures requiring two to three hours. Parenteral administration of Tetracaine hcl stabilizes the neuronal membrane and prevents initiation and transmission of nerve impulses thereby effecting local anesthesia. The onset of action is rapid, and the duration is prolonged (up to two or three hours or longer of surgical anesthesia).Tetracaine hcl is detoxified by plasma esterases to aminobenzoic acid and diethylaminoethanol.
