Nitrazepam pills belong to the benzodiazepine group of medications and are used for the short-term treatment of insomnia. This medication shortens the time it takes to fall asleep, prevents frequent awakening during the night and waking too early in the morning. Insomnia can have a negative impact on almost every daytime task as it significantly impairs cognitive functioning and so nitrazepam is an effective way to treat this distressing and disabling condition.
