Brand name: Tambocor TM

Listen to the Pronunciation:

Active ingredients: flecainide

What it is used for

Supraventricular arrhythmias: (a) due to pre-excitation syndromes, eg Wolff-Parkinson-White and Lown-Ganong-levine syndromes. (b) due to dual AV nodal pathways in patients with debilitating symptoms. (c) paroxysmal atrial fibrillation/flutter (PAF) associated with disabling symptoms. Although TAMBOCOR may be effective in supraventricular arrhythmias in patients with structural heart disease, its use has been associated with life threatening and occasionally fatal ventricular arrhythmias. In these patients, particularly in the presence of impaired left ventricular function, TAMBOCOR should be used with extreme caution, preferably after other antiarrhythmic drugs have been tried or considered inappropriate. Use of TAMBOCOR in chronic atrial fibrillation has not been adequately studied and is not recommended. 2. Life threatening ventricular arrhythmias not controlled by other drugs. Intravenous TAMBOCOR is indicated when rapid control or short-term prophylaxis of the above arrhythmias is the main clinical requirement. All use of the injection should be in hospitals only. TAMBOCOR tablets are used for continuous maintenance of normal rhythm following initial oral or intravenous therapy or conversion by other means. Prescribers should also consult the "Warnings" and "Precautions" section of the approved Product Information.
