Klonopin is used for the treatment of which condition?

Klonopin, known generically as clonazepam, is primarily indicated for the treatment of seizures. It belongs to a class of medications called benzodiazepines, which are effective in managing various seizure disorders, including absence seizures and myoclonic seizures. The mechanism of action involves enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA), which helps to calm overactive nerve activity in the brain that leads to seizures.

While Klonopin can have other uses, such as managing panic disorders, its primary and most well-known application is in controlling seizures, making the answer related to seizures the most relevant choice.
