Tosymra (sumatriptan nasal spray) is used as an acute treatment of migraine with or without aura in adults.1
What is the active ingredient in Tosymra?
The active ingredient in Tosymra is sumatriptan, a selective 5-HT1B/1D receptor agonist.2
How does Tosymra work?
While there are currently other sumatriptan nasal sprays available on the market, Tosymra has a different delivery method. An excipient is an inactive substance that works as a vehicle to deliver medicine and allow the body to absorb the drug.1
The inactive ingredient in Tosymra delivers the drug quickly and efficiently, with people absorbing as much drug as they would if they were to have a 4 mg sumatriptan injection. This high absorption rate means that Tosymra can work quicker and provide faster relief from migraine.2
