Proconvulsant
Pronunciation: /ˌproʊkənˈvʌlsənt/
A substance or condition that increases seizure susceptibility or lowers seizure threshold.
Full Definition
Proconvulsant refers to any factor that increases the likelihood of seizures by lowering seizure threshold or enhancing neuronal excitability. This includes certain medications (such as tramadol, bupropion, or fluoroquinolones), metabolic disturbances (hypoglycemia, hyponatremia), sleep deprivation, alcohol withdrawal, and various toxins. Understanding proconvulsant effects is crucial for medication selection in epilepsy patients and risk assessment in vulnerable populations. Some medications may be proconvulsant in overdose situations even if they are safe at therapeutic doses.
Usage
