How Stozina 500 Tablet Works

Stozina 500 Tablet works by targeting the electrical and chemical processes inside the heart muscle cells. During chronic chest pain, heart cells can experience an abnormal buildup of sodium. This excess sodium leads to an overload of calcium, which prevents the heart muscle from fully relaxing between beats. By selectively blocking these late sodium channels, Stozina 500 Tablet prevents calcium buildup. This allows the heart muscle to relax properly, improving blood flow and oxygen delivery to the heart without altering your normal resting heart rate or blood pressure.
