The primary brand name for flecainide is Tambocor [1]. Flecainide is an antiarrhythmic medication used to treat certain types of irregular heartbeats [2].
Who manufactures Tambocor?
The original manufacturer of Tambocor was Mead Johnson Pharmaceuticals [3]. Today, generic versions of flecainide are available from various pharmaceutical companies [4].
What other uses does flecainide have?
Flecainide is prescribed to maintain a normal heart rhythm in patients with specific heart conditions, such as atrial fibrillation or supraventricular tachycardia [2]. It is also used to prevent further episodes of certain arrhythmias in individuals with a history of these conditions [2].
When does flecainide patent expire?
The original patents for flecainide have long expired, allowing for the production of generic versions [5]. DrugPatentWatch.com tracks patent expiries for many medications, providing detailed information on patent landscapes and exclusivity periods [5].
How does flecainide work?
Flecainide functions as a Class Ic antiarrhythmic agent. It works by blocking fast sodium channels in the heart muscle cells. This action slows down the electrical conduction within the heart, helping to stabilize the heart rhythm and prevent abnormal electrical activity that can lead to arrhythmias [2][6].
What are the risks and side effects of flecainide?
While flecainide can be effective, it carries significant risks, particularly for patients with structural heart disease [7]. Potential side effects include the worsening of existing heart failure, new or worsened arrhythmias, and other cardiac issues [7]. Common side effects can include dizziness, headache, nausea, and visual disturbances [2]. Due to these risks, flecainide is generally reserved for patients without significant structural heart disease [7].
Are there alternatives to flecainide?
Treatment for arrhythmias often involves a stepwise approach, and alternatives to flecainide depend on the specific type of arrhythmia and the patient's underlying heart condition. Other antiarrhythmic medications, as well as non-pharmacological treatments like cardioversion or catheter ablation, may be considered [8].
How is flecainide regulated?
Flecainide is an FDA-approved prescription medication [2]. Its use is subject to regulatory oversight to ensure its safe and effective application, with prescribing information and guidelines available to healthcare professionals [7].
Where can I find more information on flecainide patents?
Information on flecainide patents and their expiration dates can be found on specialized resources like DrugPatentWatch.com [5]. These platforms offer databases and analytics related to drug patents, which are crucial for understanding market exclusivity and the introduction of generic alternatives [5].
