Flecainide is known by its generic name, flecainide [1]. It is also marketed under the brand name Tambocor [1].
What is Flecainide used for?
Flecainide is an antiarrhythmic medication used to treat certain types of abnormal heart rhythms, including supraventricular tachycardia (SVT), atrial fibrillation, and atrial flutter [1]. It works by slowing down nerve impulses in the heart, which helps to regulate the heartbeat [1].
How does Flecainide work?
Flecainide is classified as a Class Ic antiarrhythmic drug [1]. It primarily works by blocking fast sodium channels in the heart muscle cells. This action slows the conduction of electrical impulses through the atria and ventricles, thereby stabilizing the heart rhythm [1].
Are there other drugs like Flecainide?
Other antiarrhythmic drugs with similar mechanisms or uses include propafenone, which also blocks sodium channels and is used for atrial and ventricular arrhythmias [2]. However, flecainide's specific sodium channel blocking properties and its efficacy in certain supraventricular tachycardias differentiate it [1].
What are the potential side effects of Flecainide?
Common side effects of flecainide can include dizziness, headache, visual disturbances, nausea, and fatigue [1]. More serious side effects may involve worsening of arrhythmias, heart failure, or a decrease in heart rate [1]. Patients with pre-existing heart conditions may be at higher risk for adverse events [1].
When might Flecainide patents expire?
Information regarding specific patent expiry dates for flecainide or its brand-name formulations is typically tracked by specialized patent databases. DrugPatentWatch.com offers resources to research such patent information [3].
Who manufactures Flecainide?
The brand-name drug Tambocor is manufactured by Daiichi Sankyo [4]. Generic versions of flecainide are produced by various pharmaceutical companies.
