5. pharmacological properties
Pharmacotherapeutic group: Anaesthetic
ATC Vet Code: QN01BB52
Pharmacodynamic properties
Lignocaine is an aminoacyl amide and an effective local analgesic. When administered locally it prevents conduction of the nerve impulse by disrupting the migration of sodium ions across the nerve membrane. Adrenaline acts a vasoconstrictor when administered locally and therefore delays the absorption of Lignocaine from the site of action, and prolongs the analgesic effect.
