2012-5-1 · Local anesthetics (LA) can be split into two classes amides (eg lidocaine prilocaine) and esters (eg benzocaine and tetracaine). The basic chemical structure of local anesthetics consists of a lipophilic group and intermediate bond (which is either an ester or an amide) and a hydrophilic group.

2020-3-23 · Chemistry of Local Anesthetics. Local anesthetics exist in ionized (cation) and unionized forms.Ionization of the drug affects its transportation across the lipid plasma membrane.The ionized form (water-soluble but lipid insoluble) of a local anesthetic is important as it is the most active at the receptor site (lipidic plasma membrane/axon).

2006-1-22 · GENERAL PROPERTIES OF LOCAL ANESTHETICS. Local anesthetics interrupt neural conduction by inhibiting the influx of sodium ions. In most cases this follows their diffusion through the neural membrane into the axoplasm where they enter sodium channels and prevent them from assuming an active or "open" state.
Local anesthetics occupy an important place in anesthesiology and dentistry (1-3).
