Articaine is a local anaesthetic that has been approved overseas for several years. Like other amide anaesthetics, articaine blocks nerve conduction when it is infiltrated around a nerve. This action is prolonged by combining the drug with a vasoconstrictor such as adre.

The combination of articaine and adre can be used for local or regional anaesthesia for dental procedures. Anaesthesia begins within six minutes and lasts for an hour. The half-life of articaine is approximately 1.8 hours. It is metabolised and then mainly excreted in the urine.
