Drugs for psychological anxiety include benzodiazepines, non-benzodiazepine anxiolytics and antidepressants, which can be used by patients under medical supervision. Benzodiazepine drugs have strong anxiolytic effects, fast onset of action, improve sleep, small adverse reactions, etc. Generally, the duration of treatment does not exceed 2-3 weeks, and can be used intermittently in mild cases. Non-benzodiazepine anxiolytics, mainly including buspirone and other drugs, are suitable for outpatient treatment and will gradually become alternatives to benzodiazepines. These drugs do not have significant adverse effects of sedation, drowsiness, or weight gain, but the effects of the drugs are weaker and have a slower onset of action. The current clinical treatment of anxiolytic drugs mainly chooses 5-hydroxytryptamine reuptake inhibitors, whose safety and efficacy have become the drugs of choice for the treatment of anxiety disorders.
