Nitrosamines can be formed through various chemical processes, including the reaction between nitrites and secondary amines in certain conditions. It is a N-Nitroso of secondary amine present in Propafenone. Nitrosamines are part of a broader class of compounds known as N-nitroso compounds. 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 N-Nitroso Propafenone from Molsyns Research.
