Outcome Measures
Primary Outcomes (2)
The achievement ratio of the 50% dose reduction of (non-)BZD hypnotics (Diazepam conversion value) at 12weeks or withdrawal without any deterioration of insomnia symptoms.
Evaluate the achievement ratio of the 50% or more of dose reduction by Participant's diary
12 weeks
The rate of subjects who achieved more than 50% dose reduction of (non-)BZD hypnotics (Diazepam conversion value) at 12 weeks or withdrawal since informed consent.
The rate of subjects who achieved more than 50% of dose reduction (Diazepam conversion value) will be assessed by Participant's diary
12 weeks
Secondary Outcomes (10)
The achievement ratio of the 50% dose reduction (Diazepam conversion value) at 4weeks and 8weeks
at 4 weeks and 8weeks
The average of the dose reduction rate at 4weeks, 8weeks and 12weeks
at 4 weeks, 8weeks and 12 weeks
The achievement ratio of the 100% dose reduction at 12weeks or withdrawal
12 weeks
The variation in total score of Pittsburg Sleep Quality Index (PSQI) at 4weeks, 8weeks and 12weeks
at 0, 4, 8 and 12 weeks
The variation in total score of Athens Insomnia Scale (AIS) at 4weeks, 8weeks and 12weeks
at 0, 4, 8 and 12 weeks
- +5 more secondary outcomes

- Patients taking (non-)BZD hypnotics at a dose exceeding 2-fold of the usual dose
- Patients taking barbiturate and non-barbiturate hypnotics and Suvorexant.
