Question Answer
Most common generalized seizuregrand mal
Rare, but life-threateningstatus epilepticus
Drug of choice for tonic-clonic and partial seizuresphenytoin (and trigeminal neuralgia) --- Barbituates and Carbamazepine are effective
Hydantoin mechanismreversibly binds to inactive sodium channels
Small percentage eliminated via saliva - may cause gingival enlargementphenytoin
Is Phenytoin safe for pregnancy?no - caution may cause cleft lip/palate (succinimides are less teratogenic)
Enhances binding of GABAbarbituates, valproic acid, BDZ
Related to tricyclic antidepressantsCarbamazepine
More effective against absence (petit mal) and partial seizuresValproic acid
Drug of choice for absence seizuresEthosuximide (clonazepam also)
Toxic hepatic metabolitesvalproic acid
Treats status epilepticusDiazepam
Treats local-anesthetic induced seizuresDiazepam
Problem with tolerance/dependencyBDZ
