Excessive Use of Sedatives/Hypnotics/Anxiolytics in Taiwan

Jen-Pang Wang

 “Sedatives, hypnotics, or anxiolytics” as de-fined in DSM-5[1] are roughly denoting to benzo-diazepines (BZDs) and benzodiazepine receptor agonists. BZDs basically containing distinct three-ring BZD structure include diazepam, ni-trazepam, triazolam, and midazolam groups, whereas BZD receptor agonists, also called Z drugs (zolpidem, zopiclone, and zalopon), do not have the three-ring BZD structure [2, 3]. Being functionally similar, all those above-mentioned drugs can give five (sedative, anxiolytic, anticon-vulsing, muscle-relaxing, and amnestic) pharma-cologic effects [3].
 In the context of this editorial, the term “BZDs” is used collectively to include BZDs and BZD receptor agonists. A developed country usu-ally have about 20 BZDs each on the market, but Taiwan has about 60 available BZDs, including those imported from the United States of America, European countries, and Japan.
