What is Lidocaine?

The Introduction of Lidocaine

Lidocaine, also known as xylocaine and lignocaine, is a medication used to numb tissue in a specific area and to treat ventricular tachycardia. It can also be used for nerve blocks. Lidocaine mixed with a small amount of epinephrine is available to allow larger doses to be used as numbing and to make it last longer. When used as an injectable it typically begins working within four minutes and lasts for half an hour to three hours. Lidocaine may also be applied directly to the skin for numbing.

The Origin of Lidocaine

Lidocaine was discovered in 1946 and went on sale in 1948. It’s the most important medications needed in a basic healthcare system. It is available as a generic medication and is not very expensive.

The Function of Lidocaine

1.Local numbing agent

The efficacy profile of lidocaine as a local anesthetic is characterized by a rapid onset of action and intermediate duration of efficacy, Therefore, lidocaine is suitable for infiltration, block, and surface anesthesia.

2.Heart arrhythmia

Lidocaine is also the most important class-1b antiarrhythmic drug; it is used intravenously for the treatment of ventricular arrhythmias (for acute myocardial infarction, digoxin poisoning, cardioversion, or cardiac catheterization).

3.Other Function

Inhaled lidocaine can be used as an antitussive (cough suppressor) acting peripherally to reduce the cough reflex. This application can be implemented as a safety and comfort measure for patients who have to be intubated, as it reduces the incidence of coughing and any tracheal damage it might cause when emerging from anesthesia. 

The Brief Introduction of Lidocaine hydrochloride injections

Lidocaine hydrochloride injections containing 40, 100, or 200 mg/mL are for the preparation of IV infusion solutions and must be diluted prior to administration. Massive overdosage resulting in cardiac arrest, seizures, and/or death may occur if administered by direct IV administration without prior dilution.
