Description

Procainamide 500 mg/mL 2 mL 25Bx is an antiarrhythmic medication used to treat certain types of life-threatening ventricular arrhythmias and to manage supraventricular arrhythmias. It is administered intravenously to stabilize heart rhythm, particularly in acute settings. Procainamide belongs to the class 1A antiarrhythmic drugs and works by inhibiting the fast sodium channels in the heart, thus slowing the conduction of electrical impulses.

The mechanism of action of procainamide involves the blockade of sodium channels, which reduces the rate of depolarization during the action potential in cardiac cells. This results in a prolonged refractory period, which stabilizes the heart's electrical conduction system and helps prevent abnormal rhythms.

Common side effects include hypotension, bradycardia, and gastrointestinal disturbances. Continuous monitoring of heart function is necessary during administration to assess the response to the drug and ensure safety. The use of procainamide should be carefully controlled, particularly in patients with renal or liver impairment.
