Medicine Description quinacard-sr 200mg
Quinacard SR is a medication that functions primarily as a Class IA antiarrhythmic agent. It inhibits sodium channels in cardiac myocytes, thereby slowing the influx of sodium ions during depolarization. This action prolongs the action potential and refractory period, which helps to stabilize the cardiac membrane and prevent abnormal electrical activity. By modulating the conduction velocity and excitability of cardiac tissues, Quinacard SR effectively restores and maintains normal sinus rhythm in patients with various cardiac arrhythmias.
