Pharmacotherapeutic group: Lidocaine, combinations.
ATCvet code: QN01BB52
Pharmacodynamic properties
Lidocaine is a local anaesthetic of the amide type, used both by injection and for local application to mucous membranes.
Pharmacokinetic properties
Lidocaine has rapid onset of action when injected and spreads rapidly through surrounding tissues. The speed of onset and duration of action of Lidocaine may be increased by the addition of a vasoconstrictor.
Adrenaline is added to local anaesthetics, such as Lidocaine hydrochloride, to slow diffusion and limit absorption as it constricts arterioles and capillaries, so prolonging the duration of the effect and lessening the danger of toxicity.
