What is Onzetra Xsail and its mechanism of action?

Onzetra Xsail is used to treat migraines. It is a powder that is inhaled by using a special breath-powered delivery device called Xsail. Migraine headaches are a type of a severe headache that affect millions of Americans. Migraine headaches can be debilitating and often significantly impact a patient’s quality of life. There is no cure for migraines. Current treatments are used to reduce the frequency and severity of migraine attacks and enable patients to return to normal functioning. The exact cause of migraines is unknown. Dilated blood vessels in the brain may play a role in the development of migraines.

The medication in Onzetra Xsail is sumatriptan, a selective 5-hydroxy-tryptamine (5-HT1B/1D) receptor agonist. Sumatriptan stimulates 5-HT1 receptors on blood vessels in the brain and reduces vasodilation of the blood vessels (constricts blood vessels). Sumatriptan also blocks the effect of chemicals that cause inflammation and pain. Other sumatriptan products are available as tablets, transdermal patch, nasal spray (solution), and subcutaneous injection.
