Xylocard is used to control heart rhythm disorders, especially conditions where the heart rate is irregular or excessively fast, such as ventricular arrhythmia. The drug works by inhibiting abnormal nerve signals in the heart muscle, which restores stability to the heart rhythm and improves its efficiency in pumping blood to the body.
Xylocard may sometimes be used as part of a medical procedure to provide a local anesthetic effect when applied to tissues due to its anesthetic properties.
