The U.S. Food and Drug Administration on August 13, 2014 approved Belsomra (suvorexant) tablets for use as needed to treat difficulty in falling and staying asleep (insomnia).
Belsomra is an orexin receptor antagonist and is the first approved drug of this type. Orexins are chemicals that are involved in regulating the sleep-wake cycle and play a role in keeping people awake. Belsomra alters the signaling (action) of orexin in the brain.
“To assist health care professionals and patients in finding the best dose to treat each individual patient’s sleeplessness, the FDA has approved Belsomra in four different strengths – 5, 10, 15, and 20 milligrams,” said Ellis Unger, M.D., director of the Office of Drug Evaluation I in the FDA’s Center for Drug Evaluation and Research. “Using the lowest effective dose can reduce the risk of side effects, such as next-morning drowsiness.”
Belsomra should be taken no more than once per night, within 30 minutes of going to bed, with at least seven hours remaining before the planned time of waking. The total dose should not exceed 20 mg once daily.
The most commonly reported adverse reaction reported by clinical trial participants taking Belsomra was drowsiness. Medications that treat insomnia can cause next-day drowsiness and impair driving and other activities that require alertness. People can be impaired even when they feel fully awake.
