Study Notes
Ethosuximide Overview
- Ethosuximide is classified as an anti-seizure drug and falls under the pharmacologic class of succinimides.
- Primarily used to treat absence seizures (petit mal seizures) in both adults and children, either alone or in conjunction with other medications.
Administration and Alerts
- Abrupt withdrawal can lead to the onset of tonic-clonic seizures; therefore, it is crucial to taper off the medication gradually.
- Categorized as pregnancy category C, indicating potential risks during pregnancy.
Pharmacokinetics
- Ethosuximide is absorbed via the gastrointestinal tract, with an onset time of approximately 4 hours; the peak and duration of action can vary.
Adverse Effects
- Patients should monitor and report any worsening symptoms such as mood changes, anxiety, depression, or thoughts of self-harm.
- Common adverse effects include stomach upset, mild nausea, diuresis, changes in weight, headache, dizziness, drowsiness, and issues with balance or coordination.
Contraindications
- Usage is not recommended for individuals with known hypersensitivity or severe liver and kidney disease.
Drug Interactions
- Ethosuximide may increase serum levels of phenytoin, which can lead to toxic effects.
- Co-administration with valproic acid may result in fluctuating serum levels, complicating therapeutic management.
Herbal and Food Interactions
- Ginkgo biloba may reduce the therapeutic effectiveness of ethosuximide, potentially compromising seizure control.
Overdose Treatment
- In the event of an overdose, induce emesis unless the patient is comatose.
- Other effective treatments include gastric lavage, activated charcoal, cathartics, or even hemodialysis to assist in eliminating ethosuximide from the system.
