Neuro Flashcards
valproate
na channel blocker, migraines, saturable metabolism, protein binding
phenytoin
na channel blocker, saturable metabolism, gingival hyperplasia, hirsutism, nystagmus, purple glove
carbamazepine
na channel blocker, autoinducer, aplastic anemia, agranulocytosis, genetic screening, trigeminal neuralgia
lamotrigine
na channel inactivation, focal seizures or adjunct to general, titration schedule, autoinducer, rash
ethosuximide
ca channel blocker, absence seizures only
fosphenytoin
phosphate added, more soluble, prodrug
phenobarbital
positive allosteric GABA-A, increased duration of cl channel opening
primidone
parent drug of phenobarbital
clonazepam
positive allosteric GABA-A, seizure maintenance
lorazepam
positive allosteric GABA-A, seizure maintenance
oxcarbazepin
less enzyme induction than carbamazepine, focal epilepsy only
eslicarbazepine
like oxcarbazepin and carbamazepine, monotherapy and once daily
gabapentin
binds ca channels, partial seizure adjunct and post herpatic neuralgia
pregabalin
like gabapentin plus diabetic neuropathy, better absorption
levetiracetam
binds SV2A, partial seizure adjunct, few contraindications
