Кветиапин

Quetiapine is a second-generation atypical antipsychotic of the dibenzothiazepine class, structurally related to clozapine. Developed by AstraZeneca and first approved by the FDA in 1997, it is prescribed for schizophrenia, bipolar disorder, and as an adjunct in major depressive disorder. It is also widely used off-label for insomnia, anxiety, and other conditions. While recreational use is uncommon, reports of misuse have emerged, primarily driven by its sedative and anxiolytic properties.
