Lidocaine is an amide-linked local anaesthetic, which aslo has anti-arrhythmic properties. The time to onset of action is 3-10mins, after which the drug's effects last 60-90mins. The duration of action may be prolonged by the addition of adrenaline to the preparation. Lidocaine is a very cheap drug, and is a component of EMLA cream.
