Severe Chronic Abuse of Zolpidem in Refractory Insomnia.

ABSTRACT: Zolpidem is an imidazopyridine nonbenzodiazepine hypnotic drug with a high affinity to the α1 subunit of the gamma amino butyric acid A receptor It is the first pharmacological option in the short-term management of sleep-onset insomnia. Initially considered a safer drug compared to benzodiazepines because of lower liability for abuse and dependence, recently, an increasing body of reports has questioned zolpidem's proneness to misuse. In this report, we describe a case of serious zolpidem abuse requiring pharmacological washout during hospitalization because of previous withdrawal seizures in a patient with chronic sleep-onset and maintenance insomnia.
