According to The Pharmaceitical Journal, Suvorexant was recently released in the United States for the treatment of insomnia in adults. Even though it has some serious side effects.....
Suvorexant (Belsomra), a first-in-class orexin receptor
antagonist drug, is now available on prescription in the
United States for adults with insomnia.
Suvorexant, which is marketed by Merck, has been shown in
clinical trials to help people with insomnia to fall asleep
faster and to stay asleep throughout the night. It is thought to
work by blocking the action of orexin, a neurotransmitter
that promotes wakefulness.
The label recommends that lowest effective dose of the drug
be used and not to exceed 20mg per day; it is available as
5 mg, 10 mg, 15 mg and 20 mg strengths. it should be taken
only once per night, within 30 minutes of going to bed, and
with at least seven hours remaining before the planned time
of waking.
In clinical trials, suvorexant was associated with side effects
including daytime sleepiness, dizziness, weakness, confusion,
feeling “drugged” or light-headed, and strange dreams. At the
request of the US Food and Drug Administration, Merck
studied next-day driving in people who had taken suvorexant
and found that the 20-mg dose was associated with impaired
driving performance.
Accordingly, people taking the 20-mg dose should be warned
against next-day driving or activities requiring full mental
alertness.
The label also notes that there is a risk of sleep-driving and
other complex behaviours while not being fully awake,
particularly if the person has consumed alcohol or other
substances with central nervous system depressant effects.
Suvorexant is contraindicated in patients with narcolepsy.
Suvorexant has been classified as a Schedule IV controlled
substance, reflecting the potential for abuse or dependence.
