Mexiletine

Mexiletine is an antiarrhythmic medication used to treat life-threatening irregular heartbeats (arrhythmias). It belongs to the class of Class 1B sodium channel blockers, which help in stabilizing the heart's electrical activity and preventing abnormal heart rhythms. Mexiletine is primarily prescribed for conditions such as ventricular arrhythmias to reduce the risk of sudden cardiac arrest. This medication is taken orally and is often used when other treatments have not been effective.

Uses of Mexiletine

• Treatment of ventricular arrhythmias
• Prevention of life-threatening irregular heartbeats
• Management of inherited arrhythmic disorders
• Helps maintain normal heart rhythm

How Mexiletine Works

Mexiletine works by blocking sodium channels in the heart, reducing the excitability of heart muscle cells. This action helps to stabilize the electrical activity in the heart and prevents abnormal heart rhythms. By decreasing the ability of the heart to generate irregular impulses, Mexiletine ensures a steady heartbeat.
