Takeda Pharmaceutical has launched ORZEYFUL, a new treatment for type 1 narcolepsy, in Japan and China.

Clinical studies showed significant improvements in symptoms and quality of life compared to placebo. ORZEYFUL is an oral orexin receptor 2 (OX2R) agonist, and Takeda plans to launch it in the U.S. next month.
