Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...

Structurally, amino esters consist of three molecular components: a lipophilic part (ester); an intermediate aliphatic chain; a hydrophilic part (amine); The chemical linkage between the lipophilic part and the intermediate chain can be of the amide-type or the ester-type, and is the general basis for the current classification of local anesthetics.
Oh, and unlike many cream-based medications, most lidocaine sprays only contain the local anesthetic lidocaine, without any other topical anesthetics. AndreyPopov / iStock.
Local anesthetics can be either ester- or amide-based. Ester local anesthetics are generally unstable in solution and fast-acting, are rapidly metabolised by cholinesterases in the blood plasma and liver, [4] and more commonly induce allergic reactions. Amide local anesthetics are generally heat-stable, with a long shelf life (around two years).
Tetracaine, also known as amethocaine, is an ester local anesthetic used to numb the eyes, nose, or throat. [2] It may also be applied to the skin before starting intravenous therapy to decrease pain from the procedure. [3] Typically it is applied as a liquid to the area. [2]
Local anesthesia, in a strict sense, is anesthesia of a small part of the body such as a tooth or an area of skin. Regional anesthesia is aimed at anesthetizing a larger part of the body such as a leg or arm. Conduction anesthesia encompasses a great variety of local and regional anesthetic techniques.
