amide or ester local anesthetic
Why is articaine classified as an amide local anesthetic?
Articaine is classified as an amide local anesthetic because of the linkage between its lipid-soluble ring and terminal amine. Its thiophene ring contains a sulfur atom, which has no immunogenic property, and an ester side chain that renders the compound inactive after hydrolysis.
What are the components of a local anesthetic molecule?
The local anesthetic molecule consists of 3 components: (a) lipophilic aromatic ring, (b) intermediate ester or amide chain, and (c) terminal amine. Each of these contributes distinct properties to the molecule ( Figure 1 ). Local anesthetic structure. All local anesthetics consist of 3 principal components, each contributing a distinct property.
Can amide local anaesthetics cause allergic reactions?
Ester local anaesthetics are known sensitisers and therefore are associated with allergic reactions [1,4]. Cross-reactivity between ester local anaesthetics is also common (see our page Allergy to benzocaine ). A hypersensitivity to amide local anaesthetics is much less common and cross-reactivity is unpredictable.
