Mexiletine is a medication primarily used to treat irregular heartbeats, particularly ventricular arrhythmias. It works by stabilizing the electrical activity in the heart, preventing erratic signals. Think of it as a traffic controller for your heart's rhythm, ensuring everything flows smoothly. It's like a software update for a glitchy heart. This drug isn't a cure, but helps manage symptoms. Itβs not a first-line treatment, but can be crucial when others fail.
