Types of Anxiety Medications: A Comprehensive Overview
Selective Serotonin Reuptake Inhibitors (SSRIs)
Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed as first-line treatments for various anxiety disorders, including generalized anxiety disorder (GAD), panic disorder (PD), and social anxiety disorder (SAD)1 2 3. These medications work by increasing the levels of serotonin in the brain, which can help improve mood and reduce anxiety. Examples of SSRIs include fluoxetine, sertraline, and escitalopram.
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)
Similar to SSRIs, serotonin-norepinephrine reuptake inhibitors (SNRIs) are also considered first-line treatments for anxiety disorders1 2 3. SNRIs increase the levels of both serotonin and norepinephrine in the brain, which can help alleviate anxiety symptoms. Common SNRIs include venlafaxine and duloxetine.
Benzodiazepines
Benzodiazepines are effective for short-term relief of severe anxiety symptoms but are generally not recommended for long-term use due to their potential for dependence and withdrawal issues1 2 3 5 6. These medications enhance the effect of the neurotransmitter GABA, producing a calming effect. Examples include diazepam, lorazepam, and alprazolam.
Azapirones
Azapirones, such as buspirone, are another class of medications used to treat anxiety, particularly GAD1 2 3. These drugs act on serotonin receptors and are considered to have a lower risk of dependence compared to benzodiazepines.
Tricyclic Antidepressants (TCAs) and Monoamine Oxidase Inhibitors (MAOIs)
Tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) are older classes of antidepressants that can be effective for anxiety disorders but are generally reserved for second- or third-line treatment due to their side effect profiles2 3 5. Examples of TCAs include amitriptyline and clomipramine, while MAOIs include phenelzine and tranylcypromine.
Anticonvulsants
Anticonvulsants like pregabalin and gabapentin are sometimes used as adjunctive treatments for anxiety disorders, particularly in cases of treatment resistance1 2 3 7. These medications can help stabilize mood and reduce anxiety symptoms.
Beta-Blockers and Alpha-Agonists
Beta-blockers (e.g., propranolol) and alpha-agonists (e.g., clonidine) are sometimes used to manage the physical symptoms of anxiety, such as rapid heartbeat and trembling1 7 8. These medications are particularly useful for situational anxiety, such as performance anxiety.
Antihistamines
Antihistamines like hydroxyzine can be used for their sedative properties to help manage anxiety symptoms1 7 8. These medications are generally considered safe and have a lower risk of dependence compared to benzodiazepines.
Novel and Emerging Treatments
Recent research has explored various novel treatments for anxiety disorders, including neuropeptides, glutamatergic agents like ketamine, and cannabinoids such as cannabidiol (CBD)1. While some of these treatments have shown promise in early trials, more extensive research is needed to confirm their efficacy and safety.
Conclusion
The pharmacological treatment of anxiety disorders includes a wide range of medications, each with its own mechanism of action, benefits, and potential drawbacks. First-line treatments typically include SSRIs and SNRIs, while benzodiazepines are reserved for short-term use due to their potential for dependence. Other options include azapirones, TCAs, MAOIs, anticonvulsants, beta-blockers, alpha-agonists, and antihistamines. Emerging treatments are also being investigated, offering hope for more effective and safer options in the future.

Psychopharmacological treatment for anxiety disorders, including SSRIs and SNRIs, can effectively be combined with psychological treatments.
Systematic ReviewEfficacy of treatments for anxiety disorders: a meta-analysis
Medications are more effective than psychotherapies for anxiety disorders, but the choice between psychotherapy and medication should be left to the patient due to potential side effects and contraindications.
