Uses For esmolol
Esmolol is used to control rapid heartbeats or abnormal heart rhythms. Esmolol is also used to treat fast heartbeat and high blood pressure during surgery, after surgery, or during other medical procedures .
Esmolol is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart .
Esmolol is available only with your doctor's prescription .
