This tertiary amine and the aromatic ring, together with the intermediate amide or ester chain, constitute the three main molecular components in the structure of a local anesthetic. Related Stories ...

In the 1940s, chemists synthesized the first amino amide anesthetic, lidocaine (Xylocaine), which didn’t carry the same allergic risk as the ester amides and lasted longer than procaine.

The analysis revealed 1,956 dental cases associated with anesthesia-related adverse events. Of these cases, a significantly higher risk of serious adverse reactions was linked to ester-based ...
