Anticonvulsant
Pronunciation: an-tee-kon-VUL-sant
Medication used to prevent or reduce the frequency of seizures; synonymous with antiseizure medication.
Full Definition
Anticonvulsant refers to medications specifically designed to prevent or control seizures by modifying electrical activity in the brain. These drugs work through various mechanisms including sodium channel blockade, calcium channel modulation, GABA enhancement, or glutamate inhibition. While historically called anticonvulsants, the preferred modern terminology is antiseizure medications (ASMs) to better reflect their broader therapeutic applications beyond convulsive seizures, including non-motor seizure types and other neurological conditions.
Usage
Usage note: While still widely used, 'antiseizure medication' is increasingly preferred in modern clinical practice.
