Update on Antiseizure Medications 2025
Continuum (Minneapolis, Minn.)
|February 3, 2025
Summary
This updated review covers antiseizure medications for epilepsy management. Newer drugs offer comparable or better efficacy and tolerability than older options, guiding optimal treatment choices.
Area of Science:
- Neurology
- Pharmacology
Background:
- This article updates previous reviews on antiseizure medication (ASM) therapy for epilepsy.
- It covers a wide range of ASMs available for managing patients with epilepsy.
Purpose of the Study:
- To provide an overview of currently available ASMs, detailing their pharmacokinetic properties, indications, and usage.
- To highlight recent FDA approvals and expanded indications for ASMs.
Main Methods:
- Individual review of ASMs, focusing on pharmacokinetics, efficacy, and tolerability.
- Comparison of newer ASMs with older agents in clinical trials.
Main Results:
- Newer ASMs like lamotrigine, oxcarbazepine, levetiracetam, topiramate, zonisamide, and lacosamide show equal or superior efficacy and tolerability for focal epilepsy compared to older drugs.
- Ganaxolone is a newly approved ASM.
- Lacosamide, pregabalin, and eslicarbazepine are effective for conversion to monotherapy in focal epilepsy.
Conclusions:
- Understanding ASM pharmacokinetics, efficacy, and tolerability is crucial for selecting appropriate epilepsy treatments.
- Rational ASM combinations should minimize pharmacokinetic and pharmacodynamic interactions.

01:08Antiepileptic Drugs: Sodium Channel Blockers
359
Antiepileptic drugs are specialized medications that prevent seizures in individuals diagnosed with epilepsy. These drugs primarily function by blocking the movement of sodium ions through channels in the neuronal membrane, inhibiting the repetitive firing of action potentials often associated with seizures.
Sodium channel blockers modulate ion channels, particularly voltage-gated sodium channels. They block only sodium ion movement.

01:20Antiepileptic Drugs: Potassium Channel Activators
142
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.

01:17Antiepileptic Drugs: Calcium Channel Blockers
297
Calcium channel blockers, a class of antiepileptic drugs, regulate the flow of calcium ions within neurons.
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

219
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.
Benzodiazepines are a well-known class of drugs used for...

Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...
