Enbumyst™ (Bumetanide Nasal Spray) 0.5mg offers patients a convenient, self-administered alternative to traditional oral and intravenous forms in an outpatient-focused therapy. Clinical data indicated a faster onset of sodium excretion and a 33% increase in absorption speed compared to oral administration¹.

Reinforcing Aptar Pharma’s commitment to advancing innovative, patient-centric delivery solutions, Corstasis Therapeutics’ Enbumyst™ therapy utilizes Aptar Pharma’s Unidose System (UDS), a single-use nasal delivery system designed for systemic drug absorption via the nasal mucosa. Aptar Pharma’s Unidose System is the trusted delivery platform behind more than 30 U.S. FDA and EMA-approved therapies across emergency and chronic care - including treatments for anaphylaxis, epilepsy, migraine and opioid overdose – and is recognized globally for its unmatched reliability, intuitive one-step usability, and proven performance with hundreds of millions of units delivered.

“We are pleased to see our Unidose System continually supporting innovative therapies that expand access and convenience for patients,” said Alex Theodorakis, President, Aptar Pharma Prescription. “This approval reflects the growing potential of nasal delivery platforms in systemic treatment and reinforces Aptar’s commitment to enabling patient-centric solutions.”
