Propafenone hydrochloride is a prescription medicine used to help regulate abnormal heart rhythms. It is available in both immediate-release and modified-release formulations. The drug is typically prescribed by a cardiologist and requires close monitoring during treatment due to its effects on heart conduction and rhythm.

This medicine works by stabilizing the electrical activity of the heart. It slows down the conduction of electrical impulses and prolongs the refractory period in heart tissues, helping to prevent irregular heartbeats. It also has mild beta-blocking properties.
