What does lidocaine do?

Lidocaine belongs to the family of medicines called local anesthetics. This medicine prevents pain by blocking the signals at the nerve endings in the skin. This medicine does not cause unconsciousness as general anesthetics do when used for surgery.

Is Articaine an amide?

Articaine is an intermediate-potency, short-acting amide local anesthetic with a fast metabolism due to an ester group in its structure.

Can you be allergic to lidocaine?

Allergic reactions may occur as a result of sensitivity either to the local anesthetic agent or to other components in the formulation. Allergic reactions as a result of sensitivity to lidocaine are extremely rare and, if they occur, should be managed by conventional means.

What are esters and amides?

The ester and amide compounds differ in terms of their stability in solution, metabolism, and allergic potential. Amides are extremely stable in solution, while esters are unstable. Para-aminobenzoic acid (PABA) is an amino-ester metabolite, which causes allergic reactions in some patients.
