Pharmacologic Approach to Insomnia.

Sleep management is essential to effective treatment of pain symptoms. Identification of the precise nature of sleep complaint, awareness of patient's age and co-morbid conditions and choice of the hypnotic medication class can help guide treatment approach. In addition to benzodiazepine and non-benzodiazepine medications acting at the GABA receptor, novel approaches, including orexin receptor agonists, may be safer and more promising pharmacologic approaches. Pharmacologic interventions, when used cautiously for a limited period of time and in complement with behavioral and cognitive approaches, can serve to improve sleep quality and significantly help in management of pain.
