Mexiletine drug class?

What drug class is mexiletine?

Mexiletine is classified as an oral antiarrhythmic medicine in the sodium-channel blocker family (Class IB), used to treat certain abnormal heart rhythms. [1]

What kind of heart rhythm does mexiletine treat?

Mexiletine is prescribed for ventricular arrhythmias, particularly when there is a need for suppression of abnormal electrical activity in the ventricles. [1]

How does mexiletine work (mechanism of action)?

As a Class IB antiarrhythmic, mexiletine works by blocking cardiac sodium channels. This slows sodium-dependent electrical conduction and changes repolarization behavior in a way that helps reduce certain arrhythmias. [1]

Are there related drug classes or comparisons patients often look for?

In clinical practice, mexiletine is commonly discussed alongside other antiarrhythmic sodium-channel–acting options, but it specifically falls under Class IB (as opposed to other antiarrhythmic classes that block different ion channels or have different electrophysiologic effects). [1]

Where can I check drug details and status?
