Role of zolpidem in the management of primary and comorbid insomnia

Insomnia is a frequent complaint characterized by difficulty in falling asleep, insufficient sleep, numerous nocturnal awakenings, early morning awakenings with the inability to resume sleep, or, in some cases, nonrestorative sleep or poor quality of sleep. Common daytime complaints include somnolence, fatigue, irritability, and difficulty concentrating and performing everyday tasks. Since insomnia is associated with a reduction in attention span, affected individuals are at an increased risk for having injuries at home or work, or for involvement in accidents while driving.
