Prilocaine is an amino acid amide in which N-propyl-DL-alanine and 2-methylaniline have combined to form the amide bond; used as a local anaesthetic. It has a role as a local anaesthetic and an anticonvulsant. It is an amino acid amide and a monocarboxylic acid amide.

The amide local anesthetics including lidocaine, bupivacaine and ropivacaine are commonly used for pain control during minor surgery or invasive procedures such as biopsies, small excisions or dental work. These local anesthetics have not been linked to serum enzyme elevations, but when given as constant infusions or repeated injections have been occasionally mentioned as possible causes of clinically apparent liver injury.
