4.3 Drug Indication

Used as a local anaesthetic and is often used in dentistry.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Prilocaine binds to the intracellular surface of sodium channels which blocks the subsequent influx of sodium into the cell. Action potential propagation and never function is, therefore, prevented. This block is reversible and when the drug diffuses away from the cell, sodium channel function is restored and nerve propagation returns.


5.2 MeSH Pharmacological Classification

Anesthetics, Local

Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate. (See all compounds classified as Anesthetics, Local.)

5.6 Metabolism/Metabolites

The amide-linked local anesthetics are, in general, degraded by the hepatic endoplasmic reticulum, the initial reactions involving N-dealkylation and subsequent hydrolysis. However, with prilocaine, the initial step is hydrolytic, forming o-toluidine metabolites that can cause methemoglobinemia.

5.8 Mechanism of Action

Prilocaine acts on sodium channels on the neuronal cell membrane, limiting the spread of seizure activity and reducing seizure propagation. The antiarrhythmic actions are mediated through effects on sodium channels in Purkinje fibers.
