Pharmacology I: Chapter 8: Seizure Drugs (Entire)
| Question | Answer |
|---|---|
| Klonopin | clonazepam; benzodiazepine |
| Tranxene | chlorazepate dipotassium; benzodazepine |
| Valium | diazepam; benzodiazepine |
| Cerybyx | fosphenytoin; hydantoin |
| Dilatin | phenytoin; hydantoin |
| Tegretol | carbemazepine; phenytoin-like drug |
| Felbatol | felbamate; phenytoin-like drug |
| Lyrica | pregabalin; phenytoin-like drug |
| Mysoline | primidone; phenytoin-like drug |
| Gabitril | tiagabine hcl; phenytoin-like drug |
| Topamax | topirimate; phenytoin-like drug |
| Depaken/Depakote | valproic acid; phenytoin-like drug |
| Zonegran | zonisamide; phenytoin-like drug |
| Zarontin | ethosuximide; succinimide |
| Celontin | methsuximate; succinimide |
| Hydantoin mechanism of action | desensitizing sodium channels in the CNS responsible for neuronal responsiveness, thereby preventing the spread of disruptive electrical charges in the brain that cause seizures |
| Hydantoin adverse effects | inability to coordinate muscle activity, confusion, dizziness, insomnia, headache, gingival hyperplasia, reduction of blood cells, hepatitis , hypotension, hyperglycemia |
| Phenytoin-Like Agents Mechanism of Action | resemble the mechanism of action of phenytoin (sodium channel desensitization) |
| Phenytoin-Like Agents Adverse Effects | drowsiness, sedation, GI upset, prolonged bleeding, visual disturbances, muscle weakness, bone marrow suppression, rash, fatal liver toxicity, weight gain, loss of hair, abdominal pain |
| Succinimides Mechanism of Action | delay entry of calcum into neurons, thus increasing the electrical threshold and suppressing EEG patterns associated with petit mal seizures. Otherwise not entirely understood. |
| Succinimides Adverse Effects | ataxia, dizziness, nervousness, headache, blurred vision, vaginal bleeding, muscle weakness, behavioral changes, abnormal liver and kidney function tests |
