Medicine Description tonocard 400mg
Tonocard 400mg Tablets is a medication that acts as a class 1B antiarrhythmic agent. It exerts its therapeutic effects primarily by blocking sodium channels in the cardiac myocytes, which stabilizes the cardiac membrane during depolarization. This action helps to limit the influx of sodium ions during phase 0 of the cardiac action potential, thereby reducing excitability and conduction velocity in the ventricles. By selectively targeting the abnormal electrical activity in the heart, particularly during heightened states of irritability, Tonocard effectively restores a normal rhythm and mitigates the risk of serious arrhythmias.

Patient Advice and Precautions

It is important to avoid abrupt discontinuation of the medication without consulting a healthcare provider, as this may exacerbate arrhythmic conditions. Regular monitoring of cardiac function may be necessary during treatment.
