Proconvulsant
Proconvulsant (lowers the seizure threshold)
- ↓ seizure threshold
- Myoclonus and tremor precede seizures
- Lowers the seizure threshold — a CNS-excitatory effect that is the reason the entity is on the board at all
- Normeperidine, meperidine’s N-demethylated metabolite, accumulates in renal impairment and with repeated dosing; myoclonus and tremor precede seizures
- Naloxone does not reverse it and may worsen it — the excitation is not opioid-receptor mediated
Drugs with this mechanism (1)
- Normeperidine — Neurotoxic meperidine metabolite; accumulation, especially with renal impairment, can cause tremor and seizures.
