Tonocard

Pronounced: TAH-nuh-card
Generic name: Tocainide hydrochloride

Why is Tonocard prescribed?

Tonocard is used to treat severe irregular heartbeat (arrhythmias). Arrhythmias are generally divided into two main types: heartbeats that are faster than normal (tachycardia), or heartbeats that are slower than normal (bradycardia). Irregular heartbeats are often caused by drugs or disease but can occur in otherwise healthy people with no history of heart disease or other illness. Tonocard works differently from other antiarrhythmic drugs, such as quinidine (Quinidex), procainamide (Procan SR), and disopyramide (Norpace). It is similar to lidocaine (Xylocaine) and is effective in treating severe ventricular arrhythmias (irregular heartbeats that occur in the main chambers of the heart).
