Key Facts

In a move that strengthens the position of Japanese pharmaceutical firms in the innovative treatments market, Takeda has received regulatory approval from the Japanese Ministry of Health, Labour and Welfare for its drug ORZEYFUL. According to reports, the medication is approved for treating narcolepsy type 1 in adults.
