Consensus for the pharmacological management of insomnia in the new millennium.

Insomnia, a common symptom throughout the world, is characterised by difficulty initiating or maintaining sleep or non-restorative sleep and is associated with significant morbidity. A comprehensive medical and sleep history and physical examination are necessary before treating patients with insomnia; the presence of co-morbidities, including medical and psychiatric disorders, or the possible use of substances that may contribute to sleeplessness should be thoroughly investigated. Non-pharmacological approaches include correction of sleep hygiene as well as behavioural treatments. Pharmacotherapy includes benzodiazepine-receptor agonists, which are the drugs of choice for this disorder. They can be subdivided into classic benzodiazepines and non-benzodiazepines. Although many agents in these classes have been prescribed, potential shortcomings include residual sedation, rebound insomnia, and psychomotor and memory impairment. Novel pharmacological strategies that address limitations of the traditional treatment approach, combined with proven modes of behavioural therapy, offer the most successful results in the management of insomnia. These advances provide the opportunity to establish these current recommendations for the optimal management of insomnia. This report from the XXII Collegium Internationale Neuro-Psychopharmacologicum Consensus Workshop outlines recommendations to serve as the foundation for developing a therapeutic plan for each patient.
