Everest Medicines Wins NMPA Approval for Etripamil Nasal Spray Cardamyst in PSVT, Bringing ER‑Free Arrhythmia Care to Greater China

Everest Medicines (HKG: 1985) announced today that its etripamil nasal spray has received marketing approval from China’s National Medical Products Administration (NMPA) for the acute treatment of paroxysmal supraventricular tachycardia (PSVT) in adults, with the goal of converting episodes back to sinus rhythm. The therapy will be commercialized under the brand name Cardamyst, marking the first self‑administered, rapid‑onset treatment option of its kind for PSVT patients in Greater China and a potential shift in how episodic cardiac events are managed — from the emergency room to the outpatient setting.
