Clonazepam is a common prescription medication that is better known by its trade name Klonopin. That\'s why some medications have been created, including Imitrex, a brand name for the drug Sumatriptan, a substance that can act on the blood vessels in your brain directly. Serotonin levels control how much blood is allowed to flow through the tiny vessels in the head. Rizatriptan. Maxalt can therefore control this blood flow by controlling how much serotonin is available. Methylphenidate.
