amide vs ester local anaesthetics
What is the structure of local anesthetic?
Chemistry—Local anesthetics are weak bases with 3 structural parts: a hydrophilic end and a lipophilic end linked by an amino ester or an amino amide bond. The bond is the basis for classifying local anesthetics into 2 groups: the amino esters and the amino amides.
