Pharmacodynamic properties

Pharmacotherapeutic group: Local anaesthetics, ATC code: N01BA05

Benzocaine is a local anaesthetic of the ester type with rapid onset, acting to produce reversible loss of sensation by preventing or diminishing the generation and transmission of sensory nerve impulses near the site of application. Depolarisation of the neuronal membrane and ion exchange are reversibly inhibited.

Pharmacokinetic properties

Benzocaine is absorbed through mucous membranes and damaged skin.

Anaesthetics of the ester type are hydrolysed by esterases in the plasma and, to a lesser extent, in the liver.
