Pacerone Uses

How Does It Work?

Pacerone belongs to a group of medications known as antiarrhythmics. Most antiarrhythmic medications are categorized using a system known as the Vaughn-Williams classification system. This system divides the medications into four general classes based on how they work.
 
Pacerone has properties of all four classes and therefore works in different ways to help control arrhythmias. However, the most important way it works is by its Class III antiarrhythmic actions.
 
Class III antiarrhythmic medications block potassium channels in the heart, preventing potassium from leaving the cells of the heart muscle. This action prolongs the heart's refractory period. The refractory period is the period of time the cells of the heart muscle will not respond to a new electrical signal. By extending the refractory period, Pacerone helps the heart tissue resist any electrical signal that is trying to cause the heart to beat prematurely.
 

Is It Safe for Children to Use Pacerone?

Pacerone is not approved for use in children, as it has not been adequately studied in this age group. However, this does not mean the medicine cannot be used in a child. Talk to your child's healthcare provider about the risks and benefits of using this medicine in children.
 

Can Older Adults Use It?

There were not enough older adults in clinical studies to determine whether they responded to this medication any differently than younger age groups. Older adults are more likely to have other medical conditions that may increase their risk for certain Pacerone side effects, and will need to be closely monitored while taking this medication.
