Propafenone EP Impurity A with CAS No: 3516-95-8 is an impurity standard of Propafenone. Propafenone is an antiarrhythmic medication used to treat certain types of irregular heartbeats (arrhythmias), particularly atrial fibrillation and atrial flutter. It belongs to the class of Vaughan Williams Class Ic antiarrhythmics. Propafenone works by inhibiting sodium channels in the heart, leading to a reduction in the rate of electrical conduction. This action helps restore a normal rhythm in the heart and prevent the recurrence of irregular heartbeats. It is important to note that propafenone is typically prescribed under close medical supervision due to its potential proarrhythmic effects and other considerations. Monitoring of heart rhythm and regular follow-ups with healthcare providers are essential during propafenone therapy. Buy high quality Propafenone EP Impurity A from Molsyns Research.
