Anticonvulsants

Also called antiepileptics, anti-seizure medicines

Anticonvulsants calm excessive electrical activity in the brain. Beyond epilepsy, several have become mainstays in quite different conditions: pregabalin and gabapentin for nerve pain, lamotrigine as a mood stabiliser in bipolar disorder. They work through different mechanisms — some on sodium channels, some on calcium channels, some on synaptic vesicle proteins — which is why one can work when another has not.

How this page is built

The facts on this page are pulled directly from official U.S. FDA datasets — they are not written from memory. Each field below names the dataset it came from, so you can check it yourself.

Plain-English summaries and drug-class explainers are written and reviewed by Sreepriya Prasannan (MSc Digital Transformation of Life Sciences (Innopharma Education / Griffith College); MSc & BSc Botany). Data is retrieved automatically from the sources above and cross-checked with AI-assisted verification (Anthropic's Claude) — brand and generic names are matched against the exact FDA product record so that a combination product or a different formulation cannot be mistaken for the drug on this page. An editor reviews the result before publication. We describe this in full in our editorial standards and corrections policy. The FDA data on this page was last retrieved on 11 Oct 2026. How every register is built: methodology · fixes we have made: corrections log.

Please verify before you rely on this. This page is general information for life-science and pharmaceutical professionals. It is not medical advice, and it has not been reviewed by a clinician — our editorial team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC) and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not automatically interchangeable, and approvals, brand names and indications differ between the US, the EU/Ireland (EMA/HPRA) and other regions. Spotted an error?
