Nonbenzodiazepine

Nonbenzodiazepines (/ˌnɒnˌbɛnzoʊdaɪˈæzɪpiːn, -ˈeɪ-/^[1]^[2]), sometimes referred to colloquially as Z-drugs (as many of their names begin with the letter "z"), are a class of psychoactive, depressant, sedative, hypnotic, anxiolytic drugs that are benzodiazepine-like in uses, such as for treating insomnia^[3] and anxiety.^[4]

Nonbenzodiazepine pharmacodynamics are similar in mechanism of action to benzodiazepine drugs, acting as GABA_A receptor positive allosteric modulators of the benzodiazepine site, and therefore exhibit similar benefits, side effects, and risks. However, nonbenzodiazepines have dissimilar or entirely different chemical structures, so are unrelated to benzodiazepines on a molecular level.^[5]^[6]
