Kainate receptor negative allosteric modulator
- ↓ glutamate-driven hyperexcitability → antiseizure
- dampens glutamate overactivity → antiepileptic and anti-craving effect
Drugs with this mechanism (3)
- Topiramate ER (sprinkle) — Sprinkle-capsule extended-release topiramate for epilepsy and migraine prevention.
- Topiramate — Weight-reducing anticonvulsant for seizures and migraine; cognitive slowing limits it.
- Topiramate ER — Extended-release topiramate for seizures; cognitive slowing, kidney stones and fetal oral clefts.
Self-check
- What neuronal change underlies the antiseizure effect of GluK negative modulation?
Reduced glutamate-driven hyperexcitability. - What additional effect is proposed alongside the antiepileptic effect in this slide?
An anti-craving effect.
