Epilepsy Flashcards
New term for partial seizures
Focal seizures (+/- secondary generalised)
Etiology Seizured
most common anti-epileptic MOA
block voltage gated Na Channels
Preferred anti-seizure agents
Generalised:
- valproate (man)
- lamotrigine (1st in women)
Focal:
- no longer carbamazepine
- now lamotrigine
Leviteracitam MOA
Synaptic vesicle protein 2A, inhibition Ca 2+ currents
Topiramate MOA
AMPA and kainite receptor blocker (Na/ K/ Ca channel)
Levetiracitam MOA
?? SV2A
Vigabatran MOA
anti GABA
barbiturate MOA
GABA receptor
Leviteracitam interactions
- Doesn’t interact with other AED drug targets
- No interactions with the oral contraceptive / warfarin
AE Leviteracitam
Fatigue, thrombocytopaenia, blurred vision, memory, personality, irritability, mood swings
– Suicidality vs. placebo (0.43 vs 0.22%)
mTOR inhibitors
Everolimus and Sirolimus
Specific AE for topioromate
attention & language
HLA subtypes -> rash in epilepsy
– HLA B*1502 CBZ induced SJS
– HLA A *3101 CBZ induced rash
Anti E to use in pregnancy
lamotrigine
All dose dependent so still try to decrease the dose as able
Drug interaction lamotrigine and valporate
work better together, but more rash
Drug interaction OCP to Lamotrigine
reduced Sz control
Anti-epileptic drug level monitoring
Reasonable evidence for phenytoin, others not so much
Can be used to assess toxicity or adherence still though
