perampanel
1st line monotherapy for general motor (tonic-clonic) seizure
Levetiracetam
lamotrigine
valproic acid/divalproex*
1st line monotherapy for myoclonic seizure
levetiracetam
valproic acid/divalproex*
1st line monotherapy for general non-motor (absence) seizure
Ethosuximide
Note: not effective in preventing other seizure types such as generalized tonic-clonic seizures and should not be used as monotherapy in children with mixed types.
1st line monotherapy for tonic or atonic seizure
valproic acid/divalproex*
medication to avoid for myotonic seizure

oxcarbazepine
vigabatrin
medication to avoid for absence seizure

1st line monotherapy for focal or unclassified tonic clonic seizure
lamotrigine
levetiracetam
lacosamide
brivaracetam
oxcarbazepine
carbamazepine
valproic acid/divalproex*
[geriatric population - gabapentin**]
which antidepressant to avoid when patient with seizure?
buproprion
decrease the threshold for seizure
what’s Status Epilepticus ?
A seizure with 5 minutes or more of continuous and/or electrographic seizure activity OR recurrent seizure activity without recovery to baseline between seizures.
Management of status epilepticus 0-5 minutes
Assessment (Airway, Breathing, Circulation), safety
Stabilization
Easy causes to stabilize
Work up as many VITAMIN CDEs as possible
Management of status epilepticus 6-10 minutes
Continue assessment, safety
Manage the easy VITAMIN CDE causes
Get the GABAs on board
Start 2 large-bore IV saline infusion
Consider Intubation to support oxygenation [at 6-10 min hypoxia will be significant and a clear airway to oxygenate is important- ASAP]
Alcohol? Thiamine MI/IV (prior to dextrose)
Hypoglycemic? Dextrose 50% IV (give is unknown BS or if low)
Get the BZD started
Lorazepam 4 mg IV OR
If not IV access:
Midazolam 10 mg IM/intranasal/buccal OR
Diazepam 20 mg rectal gel or IV
Management of status epilepticus 11-30 minutes
Continued assessment and safety
Keep managing any VITAMIN CDEs causes
Keep the GABAs going
Load with other AEDs
Generalize tonic/clonic
Levetiracetam OR
Phenytoin OR
Valproic acid OR
Lacosamide OR
Brivaracetam
Prepare for ICU and intubation
what are five basic mechanism of actions for anti-seizure medications
- sodium channel blockers
- calcium channel blockers
- promote potassium efflux
- block glutamate receptors (AMPA and NMDA receptor blockers)
- increase GABA
