Cov tshuaj loog hauv zos tuaj yeem faib ua ob chav sib txawv: esters thiab amides. Cov tshuaj loog hauv zos hauv cov amino ester chav kawm suav nrog procaine, chloroprocaine, thiab tetracaine. Amino amides siv kho mob suav nrog lidocaine, mepivacaine, prilocaine, bupivacaine , levobupivacaine, thiab ropivacaine.
Yog li ntawd, cov tshuaj loog hauv zos twg yog esters?
