beta-adrenergic blockers

Beta-adrenergic blockers, or beta blockers, are medications that reduce the heart's workload by blocking certain signals (adrenaline and noradrenaline) from binding to beta receptors on the heart. This leads to a slower heartbeat and decreased blood pressure, helping manage conditions like high blood pressure, angina, and arrhythmias. They can also protect the heart after a heart attack. Beta blockers are effective but may cause side effects such as fatigue or cold hands. They are prescribed under medical supervision to help improve cardiovascular health and prevent complications.
