New dissolving film may stop dangerous episodes in rare nerve disease

This study tests a medicated film placed under the tongue to quickly ease severe episodes (autonomic crises) in people with familial dysautonomia. The film contains dexmedetomidine, a drug that calms the body's stress response. Researchers will check if it reduces symptoms like high blood pressure, rapid heart rate, and vomiting. The study involves 15 people aged 16 and older who have had at least one crisis in the past year.
