Description
Sources: http://www.drugbank.ca/drugs/DB00750

Prilocaine is a local anesthetic that is similar pharmacologically to lidocaine. 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. 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. Currently, Prilocaine is used most often for infiltration anesthesia in dentistry.
