Nasal spray could tame racing heart in AFib patients
NCT ID NCT06716021
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an investigational nasal spray called etripamil for people with atrial fibrillation (AFib) who experience episodes of dangerously fast heart rate. About 750 adults will be randomly assigned to use either the real spray or a placebo at home when symptoms start. The goal is to see if the spray can quickly lower heart rate within 30 minutes, potentially offering a convenient way to manage sudden episodes without a trip to the hospital.
