Trimethadione is a medication used primarily in the treatment of epilepsy, specifically for the management of absence seizures. It belongs to the class of oxazolidinediones, which are known for their anticonvulsant properties.
Pharmacology
Trimethadione works by modulating the activity of voltage-gated calcium channels in the brain. This action helps to stabilize neuronal membranes and reduce the frequency of seizure activity. The drug is metabolized in the liver to its active metabolite, dimethadione, which is responsible for its therapeutic effects.
Medical uses
Trimethadione is primarily indicated for the treatment of absence seizures, also known as petit mal seizures. These seizures are characterized by brief, sudden lapses in attention and activity, often occurring in children. Trimethadione is typically used when other medications, such as ethosuximide or valproic acid, are not effective or cause unacceptable side effects.
Side effects
The use of trimethadione can lead to several side effects, some of which may be serious. Common side effects include:
Serious side effects may include:
- Blood dyscrasias such as agranulocytosis and aplastic anemia
- Hepatotoxicity
- Dermatological reactions such as rash and Stevens-Johnson syndrome
Contraindications
Trimethadione is contraindicated in patients with a history of hypersensitivity to the drug or any of its components. It should be used with caution in patients with liver disease or blood disorders.
History
Trimethadione was first introduced in the 1940s as one of the earliest anticonvulsant medications. It was widely used for the treatment of absence seizures before the development of newer agents with improved safety profiles.
