How Does Tikosyn Work?
Tikosyn belongs to a group of medications known as Class III antiarrhythmics. Class III antiarrhythmic medications block potassium channels in the heart, preventing potassium from leaving the heart muscle cells. This action extends the period of time that heart cells will not respond to a new electrical signal.
Atrial fibrillation or atrial flutter can occur when an electrical signal comes through too soon and prematurely activates heart tissue, leading to a rapid heart rate. By blocking potassium channels, Tikosyn helps the heart tissue resist any premature electrical signal.
