Pharmacology Antiseizure Drugs

Major Drug Classes and Individual Agents

Topic overview

Start with the big picture

The lesson provides a mechanism-based map of antiseizure drugs, pairing each class with representative agents. Sodium channel blockers are described in relation to reduced neuronal excitability and seizure propagation, while T-type calcium channel blockers are linked to thalamic oscillations and absence seizures. Other groups include broad-spectrum mixed-mechanism agents, SV2A binders, α₂δ calcium channel ligands, and drugs that modulate GABA or glutamate signaling. The topic also covers carbonic anhydrase–inhibiting agents, a potassium channel opener, an mTOR inhibitor for tuberous sclerosis–related seizures, and prescription cannabidiol. This preview introduces the classification framework; the full lesson develops the individual classes and their key agents in greater detail.

Learning objectives

What you'll learn

  • Classify major antiseizure drug groups by their primary molecular target or mechanism.
  • Identify representative agents in the principal antiseizure drug classes.
  • Describe how sodium channel blockers affect neuronal firing and seizure propagation.
  • Explain the connection between T-type calcium channel blockers and absence seizures.
  • Recognize additional antiseizure mechanisms involving GABA, glutamate, SV2A, and mTOR.
