Lignocaine Hydrochloride I.P. 2% Adrenaline I.P. 1:80,000
Mode of Action:
Local anaesthetics reversibly block nerve transmission, when applied to a limited area of the body. They bind to the sodium channels in the nerve membrane and prevent the entry of sodium ions in response to the membrane’s deplorization. A vasoconstrictor like Adrenaline added to a local anaesthetic may significantly prolong the anaesthetic’s duration of action by reducing the blood flow around the injection site. This in turn may reduce the local anaesthetic’s peak plasma concentration and the risk of adverse systemic reactions.
- Local Anaesthesia by infiltration or nerve block injection.
Xicaine is contraindicated in patients with known hypersensitivity to local anaesthetic of amide type, or the presence of vasoconstrictor. Adrenaline is contraindicated in patients with arterial hypertension, coronary disease, valvular cardiac disease.
