Onzetra Xsail (sumatriptan) is a fast-acting, intranasal serotonin 5-HT1B/1D receptor agonist (triptan) indicated for the acute treatment of migraine with or without aura.
The approval of Onzetra Xsail is based on data from the TARGET trial of 230 migraine sufferers who self-administered either Onzetra or placebo using the Xsail Breath Powered Delivery Device when experiencing moderate to severe migraine pain. Study results demonstrated that a significantly greater proportion of Onzetra Xsail patients reported headache relief at 30 minutes and at every time point up to two hours post-dose compared with those using the placebo device.
The recommended dose of Onzetra Xsail is 22 mg, administered by use of one nosepiece (11 mg) in each nostril, with a maximum of two doses in any 24-hour period. A dose is delivered when the user exhales into the device, automatically closing the soft palate and sealing off the nasal cavity. Through a sealing nosepiece placed into the nostril, the exhaled breath carries medication from the device directly into one side of the nose and deep into the nasal cavity where absorption is more efficient and consistent. Closure of the soft palate helps prevent swallowing and reduce GI absorption.
The most common side effects reported include abnormal product taste, nasal discomfort, rhinorrhea, and rhinitis.
