[Sleep regulation as a complex process].

A retrospective analysis of views on the regulation of the «sleep-wakefulness» cycle from the reticular theory of sleep to the Saper's model was carried out. A modified version of the Saper's trigger made it possible to use the results of a comparative analysis of drugs used in the treatment of sleep disorders to develop new, comprehensive, effective approaches to the pharmacotherapy of the most common sleep disorders. It seems that this approach will be useful in the development of effective pharmacotherapy for sleep disorders.
