Lancora (Ivabradine) is a heart medication that is used in addition to other medications to treat stable, chronic (long-term) heart failure in adults who have a heart rate of 77 or more beats per minute. It reduces the heart rate by acting on specific cells in the heart that cause the heart muscle to contract, or "beat."  An increased heart rate is associated with increased hospital admissions and an increased risk of dying from heart failure.
