Tetracaine Hydrochloride yog dab tsi?
Tetracaine HCl yog tsim los ntawm 4-butylaminobenzoic acid.Cov ethyl ester yog tsim los ntawm cov tshuaj tiv thaiv acid-catalyzed esterification.Base-catalyzed transesterification yog ua tiav los ntawm boiling ethyl ester ntawm 4-butylaminobenzoic acid nrog ntau tshaj 2-dimethylaminoethanol nyob rau hauv lub xub ntiag ntawm ib tug me me ntawm sodium ethoxid.
Tetracaine (INN, tseem hu ua amethocaine; lub npe lag luam Pontocaine.

Hauv kev tshawb fawb biomedical, tetracaine yog siv los hloov cov haujlwm ntawm calcium tso tawm raws (ryanodine receptors) uas tswj kev tso tawm calcium los ntawm cov khw muag khoom intracellular.Tetracaine yog ib qho allosteric blocker ntawm kev ua haujlwm channel.Thaum tsis tshua muaj siab, tetracaine ua rau muaj kev cuam tshuam thawj zaug ntawm cov xwm txheej calcium uas tshwm sim, thaum nyob rau hauv siab, tetracaine blocks tso tawm tag nrho.
Dab tsi yog qhov txawv ntawm qhov kev siv tshuaj loog ntawm tetracaine hydrochloride hmoov thiab lidocaine, procaine?
Cov tshuaj loog hauv zos: Tetracaine puag> tetracaine hcl> lidocaine> lidcaine hcl> benzocaine> procaine> procaine hcl, tab sis cov kev mob tshwm sim kuj tseem yuav nce ntxiv.
