Hong Kong researchers develop ‘world-first’ nasal spray for rapid stroke aid

Researchers at the University of Hong Kong have developed a novel nasal spray designed to provide rapid first aid for ischemic stroke patients. This world-first treatment delivers neurotherapeutic powder directly to the brain, aiming to mitigate stroke damage. The spray is intended for initial administration by paramedics, with plans for wider rollout to high-risk individuals in care facilities and eventually the general public via pharmacies. The development was a collaborative effort between HKU's Li Ka Shing Faculty of Medicine and its Advanced Biomedical Instrumentation Centre. Clinical trials for this innovative stroke aid are anticipated to commence by 2030.
