Editing Insomnia (section)

==== Z-Drugs ====
[[Nonbenzodiazepine]] or [[Z-drug]] sedative–hypnotic drugs, such as [[zolpidem]], [[zaleplon]], [[zopiclone]], and [[eszopiclone]], are a class of hypnotic medications that are similar to benzodiazepines in their mechanism of action, and indicated for mild to moderate insomnia. Their effectiveness at improving time to sleeping is slight, and they have similar—though potentially less severe—side effect profiles compared to benzodiazepines.<ref>{{cite journal | vauthors = Huedo-Medina TB, Kirsch I, Middlemass J, Klonizakis M, Siriwardena AN | title = Effectiveness of non-benzodiazepine hypnotics in treatment of adult insomnia: meta-analysis of data submitted to the Food and Drug Administration | journal = BMJ | volume = 345 | pages = e8343 | date = December 2012 | pmid = 23248080 | pmc = 3544552 | doi = 10.1136/bmj.e8343 }}</ref> Prescribing of nonbenzodiazepines has seen a general increase since their initial release on the US market in 1992, from 2.3% in 1993 among individuals with sleep disorders to 13.7% in 2010.<ref name="Kaufmann" />
