Description

Lidocaine 2% 50 mL MDV is a sterile, injectable solution used as a local anesthetic and antiarrhythmic agent. It is designed for administration via injection to block nerve signals in specific areas or to stabilize abnormal heart rhythms. The active ingredient, lidocaine hydrochloride, is a short-acting amide-type anesthetic that provides rapid onset of action for temporary numbing or pain relief during medical procedures.

As a local anesthetic, lidocaine works by inhibiting sodium ion influx through voltage-gated sodium channels in neuronal membranes. This action prevents the initiation and transmission of nerve impulses, resulting in localized numbness. In its antiarrhythmic application, lidocaine stabilizes cardiac cell membranes by decreasing the excitability of myocardial tissue, which helps control ventricular arrhythmias such as ventricular tachycardia or fibrillation.

Lidocaine 2% is packaged in a 50 mL multiple-dose vial (MDV), allowing for repeated withdrawals when aseptic techniques are strictly followed. Its broad clinical applications include use in minor surgical procedures, dental procedures, and emergency treatment of life-threatening arrhythmias.
