As a domain expert in pharmacology, I can explain how Multaq (dronedarone) works.
Multaq is an antiarrhythmic medication, which is used to treat atrial fibrillation (AF), a condition where the heart's upper chambers (atria) beat irregularly. It helps to maintain a normal heart rhythm by slowing down the electrical impulses in the heart.
The drug works primarily by blocking certain ion channels in the heart. Specifically, it is a multichannel blocker. It blocks the sodium and potassium channels, which are responsible for the movement of electrical impulses through the heart muscle. By blocking these channels, Multaq reduces the speed at which these impulses are conducted, which can help to prevent the rapid and irregular heartbeats associated with atrial fibrillation.
Additionally, Multaq also has some effects on the adenosine pathways, which can further help to stabilize the heart rhythm.
It's important to note that Multaq is not a cure for atrial fibrillation; it is a treatment to help control the symptoms and reduce the frequency of episodes.

Increased flow of charged particles produces the excessive electrical activity that leads to atrial fibrillation and rapid heart rate. By reducing the flow of potassium through the channels, Multaq slows down contractions in the atria and so prevents fibrillation and lowers the heart rate.
