Description

General description

Tetracaine belongs to the amino-ester class and has a pKa of 8.46.[1]

Application

Tetracaine can be used as a research tool for studying E-C coupling in both skeletal as well as cardiac muscle.[2] The product is a local anaesthetic drug used for studying the impact of numerous drugs on Tumour-necrosis-factor (TNF)-mediated cytotoxicity as well as TNF-induced arachidonic acid release.[3]

Tetracaine has been used as an anesthetic and to lower the glucose synthesis in upper small intestinal infusions.[4] It has also been used to inhibit ryanodine receptors (RyRs) in rats.[5]

Topical ophthalmic anesthetic; used for spinal anesthesia

Biochem/physiol Actions

Blocks voltage-sensitive release of Ca²⁺ from sarcoplasmic reticulum.

Tetracaine also refers as 4-(Butylamino)benzoic acid 2-(dimethylamino)ethyl ester interfere with calcium movement in muscle and non-muscle cells and can inhibit potassium-induced as well as caffeine-induced shortening of outer hair cells (OHC′s). But, the product can′t inhibit electrically-induced shortening of OHC′s.[6]The product can also stimulate caspase activation and inhibits pro-survival signalling pathways which in turn induce human renal cell apoptosis.[7]

Tetracaine blocks intracellular sodium channels.[1] It mediates phosphorylation of eukaryotic initiation factor 2 (eIF2 α) via translational inhibition of P-body formation.[8]

Preparation Note

250 mg of tetracaine dissolves in 5 ml of EtOH to yield a clear, colorless solution. The product is also soluble in chloroform and ether at a ratio of 1:2 and in ethanol at 1:5. It is very slightly soluble in water.
