Atzumi is a brand-new FDA-approved migraine nasal powder containing dihydroergotamine. Learn what it is, how it's used, the correct dosage, and what makes it different.

Atzumi is a prescription medication approved by the FDA in April 2025 for the acute treatment of migraine. If you've been prescribed Atzumi or are researching whether it might be right for you, here's a complete overview of what it is, how it's used, and what makes it different from other migraine treatments.

What Is Atzumi?

Atzumi is the brand name for dihydroergotamine (DHE) nasal powder, manufactured by Satsuma Pharmaceuticals, Inc. (Durham, NC). It is a prescription-only migraine medication that delivers DHE — an ergot alkaloid with a 70+ year history in migraine treatment — through the nasal cavity using a novel dry powder delivery system.

Each Atzumi device contains 5.2 mg of dihydroergotamine (equivalent to 6.0 mg dihydroergotamine mesylate). Atzumi comes in a carton of 8 single-dose devices, each individually sealed in a protective foil pouch. The device requires no assembly or priming before use — you simply insert it into one nostril and squeeze the air pump three times while inhaling.

What Is Atzumi Approved For?

The FDA has approved Atzumi for the acute treatment of migraine with or without aura in adults. "Acute treatment" means it's taken when a migraine starts — it's not a preventive medication. Atzumi will not stop migraines from happening; it treats them once they begin.

Atzumi is NOT approved for:

Prevention of migraine (prophylaxis)

Hemiplegic migraine

Migraine with brainstem aura

Pediatric patients (safety/efficacy not established in children)

How Is Atzumi Different from Other Migraine Medications?

Atzumi belongs to the ergotamine class of migraine medications. Unlike the triptans (which have been the dominant acute migraine class since the 1990s) or the newer CGRP receptor antagonists (gepants), Atzumi works through multiple receptor pathways that give it some unique clinical advantages:

Effective late in an attack: DHE can relieve migraine even when taken hours after onset, unlike triptans which work best early in the attack.

Lower recurrence rate: DHE has a lower headache recurrence rate than most triptans, meaning the migraine is less likely to return later the same day.

Effective for triptan non-responders: Patients who don't respond to triptans often respond well to DHE.

What's the SMART Technology in Atzumi?

Atzumi uses Satsuma's proprietary SMART platform — Simple MucoAdhesive Release Technology. This is a dry powder delivery system that, when administered through the nostril, deposits DHE particles on the nasal mucosa where the drug is rapidly absorbed into the bloodstream. Unlike liquid nasal sprays (which can drip back out or be inconsistently absorbed), the powder adheres to the mucosal surface and achieves more consistent drug delivery.

In Phase 1 studies, Atzumi achieved effective DHE blood concentrations within approximately 10 minutes — faster and more consistent than the 30–60 minutes typically needed for liquid DHE nasal spray.

How Do You Take Atzumi?

Atzumi is for nasal use only. Here's a step-by-step overview of how to use it:

Blow your nose gently to clear your nostrils.

Open the foil pouch and remove the Atzumi device.

Pull the clear cap straight off. Twist or bend the round blue tab to break it off.

Insert the blue nozzle all the way into ONE nostril. Do not squeeze before inserting.

Squeeze the white air pump 3 separate times while inhaling through your nose each time. Use fast, complete squeezes.

Allow the pump to expand back between squeezes.

Discard the device after use — it contains one dose only.

Atzumi Dosage

Starting dose: 5.2 mg (one device) into one nostril at the onset of migraine symptoms

Repeat dose: If needed, may take another 5.2 mg dose at least 1 hour after the first

Maximum per 24 hours: 10.4 mg (2 doses)

Frequency limit: No more than 4 doses per 7 days; safety beyond 12 doses per 30 days not established

Bottom Line

Atzumi is a significant advance in DHE delivery for acute migraine, combining a well-established drug with a modern nasal powder platform. To understand how it works at the molecular level, see our companion guide on Atzumi's mechanism of action.

Frequently Asked Questions

Atzumi (dihydroergotamine nasal powder) received FDA approval on April 30, 2025. It was developed by Satsuma Pharmaceuticals, Inc. (Durham, NC), a subsidiary of Shin Nippon Biomedical Laboratories (SNBL), and was previously known as STS101 during clinical development.

Both Atzumi and Migranal contain dihydroergotamine mesylate (DHE) for acute migraine treatment. They differ in formulation: Migranal is a liquid nasal spray, while Atzumi is a dry powder using SMART (Simple MucoAdhesive Release Technology) delivery. Atzumi achieves effective DHE plasma concentrations within ~10 minutes and has higher peak drug concentrations compared to Migranal's liquid spray.

There are no capsules in Atzumi — it's a powder prefilled in a single-dose nasal device, not a capsule to be swallowed. Atzumi is for nasal administration only. The device must be inserted into the nostril and squeezed 3 times while inhaling. The drug is absorbed through the nasal mucosa and enters the bloodstream through the lungs and nasal passages, bypassing the gastrointestinal tract.

In Phase 1 pharmacokinetic studies, Atzumi achieved effective DHE plasma concentrations within approximately 10 minutes of administration. In the ASCEND Phase 3 trial, 66.5% of migraine attacks showed headache relief at 2 hours post-dose, and 94.3% showed headache relief at 24 hours. Individual response times vary — some patients experience relief faster.
