About ONZETRA Xsail

ONZETRA Xsail is an intranasal medication delivery system containing sumatriptan, the most commonly prescribed migraine medication. The medication is delivered intranasally utilizing the novel Xsail Breath Powered® delivery technology. ONZETRA Xsail is a fast-acting dry-powder intranasal form of sumatriptan for the acute treatment of migraine. Sumatriptan is the most widely used prescription migraine medication and has been used safely for over 20 years. Sumatriptan is contraindicated for certain patients, including those with a history of coronary artery disease (CAD) or coronary vasospasm.

The Breath Powered delivery technology relies on the user's breath to propel medication into the nasal cavity where absorption is efficient and consistent. The user exhales into the device, automatically closing the soft palate and sealing off the nasal cavity while dosing. Through a sealing nosepiece placed into the nostril, the exhaled breath carries medication from the device directly into one side of the nose. Narrow nasal passages are gently expanded and medication is dispersed into the nasal cavity reaching areas where it can be rapidly absorbed. As the medication is delivered, the air flows around to the opposite side of the nasal cavity and exits through the other nostril. Closure of the soft palate helps prevent swallowing and reduce GI absorption.

ONZETRA Xsail is indicated for the acute treatment of migraine with or without aura in adults.

About Migraine

Migraine represents an area of significant unmet medical need. According to the Centers for Disease Control and Prevention, over 37 million Americans suffer from migraine headaches. The triptan class of medications is generally considered the standard of care with over 14 million prescriptions written annually. Sumatriptan is the class leader with a market share of over 50 percent, making it the most commonly prescribed migraine drug in the U.S., and 100 mg tablets are the most commonly prescribed form of sumatriptan.
