Anxiolytic Drugs: Overview
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic circuitry.

This systematic review evaluates treatments for generalized anxiety disorder (GAD), finding various interventions like antidepressants and cognitive behavioral therapy effective. Further research is needed to confirm long-term safety and efficacy for GAD patients.
Area of Science:
- Psychiatry
- Clinical Psychology
- Pharmacology
Background:
- Generalized anxiety disorder (GAD) affects up to 20% of the population, often co-occurring with other health issues.
- Full remission from GAD is achieved by less than half of individuals within five years.
- Potential contributing factors to GAD include genetic predisposition and history of psychological trauma.
Purpose of the Study:
- To systematically review and evaluate the effects of various treatments for generalized anxiety disorder (GAD).
- To synthesize evidence on the effectiveness and safety of pharmacological and non-pharmacological interventions for GAD.
Main Methods:
- Conducted a systematic literature review up to May 2011, searching major databases (Medline, Embase, Cochrane Library).
- Included data from 74 systematic reviews, randomized controlled trials (RCTs), and observational studies.
- Incorporated safety information from regulatory agencies like the FDA and MHRA.
Main Results:
- Identified numerous interventions for GAD, including antidepressants (e.g., duloxetine, sertraline), benzodiazepines, and cognitive behavioral therapy.
- Assessed the quality of evidence for different interventions using the GRADE system.
- Compiled data on the effectiveness and safety profiles of evaluated treatments.
Conclusions:
- The review presents findings on the effectiveness and safety of diverse GAD interventions.
- Interventions covered include abecarnil, specific antidepressants, antipsychotics, applied relaxation, benzodiazepines, buspirone, cognitive behavioral therapy, hydroxyzine, and pregabalin.
- This systematic review serves as a resource for understanding current treatment options for GAD.
