Antiseizure/Status Epilepticus Flashcards
When do you initiate anti seizure drug therapy in patients?
2+ unprovoked seizures
When do you consider discontinuing ASD therapy
- Seizure free for 2-4 years
- Complete seizure control within one year of onset
- Onset of seizure between 2-35 years of age
AND normal neurologic exam/EEG
List the 3 MOA of ASDs
- Increase GABAeric inhibitory transmission
- Decrease Glutamatergic excitatory transmission
- Modify ionic conductance-nerve impulse propagation
List the presynaptic voltage gated Na+ channel drugs
- Phenytoin
- Carbamazepine
- Lamotrigine
- Lacosamide
List the presynaptic voltage gated Ca++ channel drugs
- Ethosurimide
- Lamotrigine
- Gabapentin
- Pregabalin
List the presynaptic voltage gated K+ channel drug
Retigabine
list the synaptic vesicle protein (SV24) drug
Levetiractam
List the two postsynaptic drugs
- AMPA Receptors
2. NMDA receptors
What drugs block the AMPA receptor

2. Blood dyscrasias
Lamotrigine (Lamictal) MOA
- Blocks Na+ and Ca++ channels
2. Decreases glutamate

Valporic acid (Depakote) MOA
Alters synthesis and degradation of GABA
Valporic acid (Depakote) clinical application
- Generalized tonic-clonic
- Focal aware/impaired
- Focal or Generalized 4.Myoclonic
- Generalized Absence
Valporic acid (Depakote) SEs
