Mexitil is a brand name for the medication called Mexiletine, which is used to treat arrhythmias, or irregular heart rhythms. This medication works by blocking the abnormal electrical impulses in the heart, which can help to regulate the heart's rhythm. While Mexitil is a commonly known brand name, there are several other synonyms for Mexiletine. These include names like Novo-Mexiletine, Lorajet, and Pluravent. These medications all contain the same active ingredient and work in the same way to treat arrhythmias. If you have been prescribed Mexitil, it is important to know these synonyms so that you can recognize it if it is prescribed under a different name.
