Food and Drug Administration (FDA) added a new warning to the lamotrigine label regarding its potential to cause cardiac conduction and rhythm abnormalities [1]
Effect of Lamictal: In vitro studies show that lamotrigine exhibits Class IB antiarrhythmic activity at therapeutically relevant concentrations
2 However, in 2011, concerns over serious cardiac arrythmias have caught the attention of regulators In most cases the initial EKG can be obtained while titrating, mainly when the individual is at the first dose of 25 mg/d because lamotrigine must be titrated slowly, and because cardiac adverse events are dose-related
Get full access to this article Lamotrigine and risk of arrhythmias: A global pharmacovigilance analysis Keywords Arrhythmias Lamotrigine Antiepileptics Drug safety Dear editor In March 2021, FDA reported a risk of arrhythmias with lamotrigine, [ [1] ] an antiseizure medication acting as sodium and calcium channel modulator [ [2] ]
, myocardial ischemia, heart failure, structural heart disease, Brugada syndrome or other sodium channelopathies)
1 Lamotrigine is the nonproprietary name for a medicine that is sold under its generic name and several brand names including Lamictal™
We conducted a rapid systematic review to
An in Severe cardiac arrhythmias developing in the course of seizures increase the risk of SUDEP (sudden unexpected death in epilepsy)
5 channels stably expressed in HEK293 cells, and on action potential (AP Lamictal did not slow ventricular conduction (widen QRS) in healthy individuals in a thorough QT study; however, it could slow ventricular conduction and increase the risk of arrhythmia in patients with structural heart disease or myocardial ischemia
One study reporting on sudden cardiac death and 3 studies with unclear sudden death definitions did not report an elevated risk of death in lamotrigine users compared to controls
In March 2021, a drug safety communication was issued by the FDA encouraging providers to carefully analyze the risk of arrhythmias in individual patients and weigh against Heart arrhythmia drug
Conclusions: Unlike flecainide or riluzole, lamotrigine promotes heterogeneous cardiac conduction slowing and enhanced anisotropic ratio in adult wild-type murine hearts
You may use the study as a second opinion to make health care decisions

Cardiac arrhythmias are extremely common, with an overall prevalence of 4
As previously stated, lamotrigine is not indicated for treatment of cardiac arrhythmias
In contrast to FDA warning, two recent studies failed to find any definite evidence for an association between lamotrigine and cardiac conduction disorders
2023
Anti-arrhythmics, including class I drugs, often carry a boxed warning in the United States based on CAST
To establish whether gabapentin, lamotrigine, levetiracetam, pregabalin, and valproic acid reduce the Nav1

Clearly, AEDs can affect cardiac action potential profile and duration and induce ECG changes of clinical relevance
Arrhythmias, Cardiac / diagnosis Cardiac Complexes, Premature / chemically Background and ObjectivesA recent Food and Drug Administration warning concerning an arrhythmogenic potential of lamotrigine created concern in the neurologic community
Patients with heart disease who take lamotrigine may be at increased risk for arrhythmias, according to a US Food and Drug Administration (FDA) review
Blood-thinning medicines can lower the risk of stroke related to atrial fibrillation and other heart arrhythmias
Several drugs used in the treatment of mental diseases are associated with an increased risk of sudden cardiac death (SCD)

Although lamotrigine is not approved to treat cardiac arrhythmias, we compared its kinetic properties of Na V 1
We conducted a rapid systematic review to
lamotrigine regarding cardiac arrhythmias, sudden cardiac death, sudden unexpected death in epilepsy (SUDEP) is a pressing clinical question

1 Lamotrigine gained its popularity owing to its good safety profile including lower rates of neurocognitive and teratogenic adverse events
To establish whether gabapentin, lamotrigine, levetiracetam, pregabalin, and valproic acid reduce the Nav1
Twelve studies showed no significant risk of SUDEP for lamotrigine users
This warning advised against the use of lamotrigine in patients with cardiac conduction disorders, prior ventricular arrhythmias, or cardiac disease or abnormality
Importantly, all hearts exposed to a therapeutic concentration of lamotrigine evidenced reentrant arrhythmia during pacing at a basic cycle length of 150 ms
The phase IV clinical study analyzes which people take Lamictal and have Arrhythmias
Compared with people without epilepsy, people with epilepsy but without medication still had an increased risk of cardiac arrhythmias (HR 1
