Abstract

New antiarrhythmics-flecainide and lorcainide-extracted from plasma were separated by TLC method on silica gel by ascending development, using suitable mobile phases. The substances were identified by reaction with indicators: Dragendorff reagent for lorcainide (up to the amount 50 ng) and acidified 15% FeCl3, followed by 15% KI and water for flecainide (up to the amount 500 ng).

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
