Histamine H(3) receptor (H(3)R) antagonists and inverse agonists in the treatment of sleep disorders.

After the discovery and characterization of the H(3)R and H(4)R receptors, they have become widely anticipated as potential therapeutic agents in the treatment of sleep disorders. In preliminary studies, histamine H(3) receptor (H(3)R) antagonists and inverse agonists have demonstrated promise in the treatment of sleep disorders associated with excessive daytime sleepiness. This review article summarizes the current research in this area and characteristics of H(3)R and H(3)R antagonists and inverse agonists in development.
