What type of agent is lignocaine classified as?

Lignocaine, also known as lidocaine, is classified as an antiarrhythmic and local anaesthetic agent due to its mechanism of action and clinical applications. As a local anaesthetic, lignocaine works by blocking sodium channels in neuronal membranes, which prevents the conduction of nerve impulses, resulting in temporary loss of sensation in the targeted area. This is particularly useful in medical procedures that require pain management without affecting consciousness.

Additionally, lignocaine is utilized in the management of certain cardiac arrhythmias. It stabilizes cardiac membranes and decreases the automaticity of ectopic pacemakers, making it effective in treating conditions such as ventricular tachycardia. Its dual role in both local anaesthesia and cardiac dysrhythmia management underscores its classification as both an antiarrhythmic and a local anaesthetic agent. Other classifications, such as antibiotic or anti-inflammatory, do not apply to lignocaine, as its primary pharmacological effects are distinct from those drug classes.
