Regulatory Approval and Clinical Data
Quviviq, a novel dual orexin receptor (搜索) antagonist discovered by Idorsia Pharmaceuticals (搜索) Ltd, received approval from the Ministry of Health, Labour, and Welfare of Japan in September.

Impact on Insomnia Treatment in Japan
Insomnia (搜索) is highly prevalent in Japan, affecting approximately 20% of Japanese adults, and is recognized as a significant national issue impacting both physical and mental health.
