Adult volunteers and caregivers were more successful at using glucagon nasal powder devices than traditional injections to treat a patient with severe hypoglycemia in a simulated situation. The devices are single-use and designed to shoot a dry powder up the nose in rescue situations. The device was safe and effective in children and teens. The results from a phase III trial showed that the powder was as effective as reversing hypoglycemia in adults as injected glucagon and easier to administer.
