Parametadione
Pharmacology
Paramethadione is an oxazolidinedione anticonvulsant similar to trimethadione that acts on the central nervous system (CNS) to reduce the number of absence seizures (often seen in epileptics). Absence seizures involve an interruption to consciousness where the person experiencing the seizure seems to become vacant and unresponsive for a short period of time (usually up to 30 seconds). Paramethadione acts on thalamic neurons in the thalamic reticular nucleus (which studies have shown to be associated with absence seizures, von Krosigk et al., 1993).

Patient Information
Dione anticonvulsants are used to control certain types of seizures in the treatment of epilepsy. They act on the
central nervous system (CNS) to reduce the number of seizures. These medicines cannot cure epilepsy and will only
work to control seizures for as long as you continue to take them.
