A major subgroup is the benzodiazepines, but representatives of other subgroups, including barbiturates, and miscellaneous agents (carbamates, alcohols, and cyclic ethers) are still in use. Newer drugs with distinctive characteristics include the anxiolytic buspirone, several widely used hypnotics (zolpidem, zaleplon, eszopiclone), and ramelteon, a novel drug used in sleep disorders.
