Levetractan is not a widely recognized term in medical or scientific literature, and it may be a misspelling or confusion with another substance. If you're referring to "levetiracetam," it is an anticonvulsant medication primarily used to treat epilepsy. Levetiracetam works by modulating neurotransmitter release and is often prescribed for various types of seizures. If you meant a different term, please provide more context for clarification.
