Mexiletine
Mexiletine
Mexiletine (pronounced: mek-si-let-een) is a class 1B antiarrhythmic medication used to treat ventricular arrhythmias. It is an oral analogue of lidocaine.
Etymology
The term "Mexiletine" is derived from its chemical name, 2-(2,6-dimethylphenoxy)-2-methylpropylamine.
Usage
Mexiletine is primarily used to treat serious ventricular arrhythmias, such as ventricular tachycardia. It works by blocking sodium channels in the heart, reducing the heart's excitability and thus preventing arrhythmias. It may also be used off-label for the treatment of chronic pain conditions, such as neuropathic pain and myotonia.
Side Effects
Common side effects of Mexiletine include nausea, vomiting, heartburn, dizziness, tremor, and unusual taste in the mouth. Serious side effects may include cardiac arrhythmia, liver problems, and seizures.
