Anxiety can be a debilitating condition, but several types of medications, collectively known as anxiolytics, can help manage its symptoms. The right medication depends on the specific type of anxiety disorder, its severity, and the patient's individual health profile. This guide explores the different classes of drugs, their mechanisms, and their uses in treating anxiety.
The Primary Name: Anxiolytic
The most direct answer to the question, "What is an anti-anxiety drug called?" is an anxiolytic. This term is derived from Greek words, with “anxio-” meaning “anxiety” and “-lytic,” meaning “to loosen”. Anxiolytics are designed to relieve the feelings of fear, dread, and muscle tension associated with anxiety by calming the central nervous system. Within this broad category, various classes of medications exist, each with a different approach to managing anxiety.
Classes of Anti-Anxiety Medications
Anti-anxiety drugs do not all work the same way. The most common classes include:
- Benzodiazepines: These are central nervous system depressants that increase the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity. They are fast-acting and highly effective for short-term and acute anxiety, such as panic attacks. However, they carry a high risk of dependence and are generally not recommended for long-term use. Common examples include Alprazolam (Xanax) and Lorazepam (Ativan).
- Selective Serotonin Reuptake Inhibitors (SSRIs): Often the first-line treatment for long-term anxiety, these antidepressants work by increasing the levels of serotonin in the brain, which plays a crucial role in mood regulation. SSRIs have fewer side effects than older antidepressants and are not habit-forming, though they can take several weeks to become fully effective. Examples include Escitalopram (Lexapro) and Sertraline (Zoloft).
- Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): Another class of antidepressants, SNRIs increase the levels of both serotonin and norepinephrine in the brain. They are effective for treating generalized anxiety disorder and often considered a first-line option alongside SSRIs. Examples include Venlafaxine (Effexor XR) and Duloxetine (Cymbalta).
- Buspirone (BuSpar): This is a non-benzodiazepine anxiolytic indicated for generalized anxiety disorder. Unlike benzodiazepines, it has a much slower onset of action but does not carry the same risk of dependence. It works by affecting serotonin and dopamine receptors in the brain.
- Beta-Blockers: These are primarily used for heart conditions but are prescribed off-label for situational anxiety, such as performance anxiety. They work by blocking the effects of norepinephrine, which helps to alleviate physical symptoms like a rapid heart rate and shaking. Propranolol is a common example.
Comparison of Anti-Anxiety Medications
When choosing an anti-anxiety medication, a healthcare provider will consider factors like the desired speed of effect, risk of dependence, and suitability for long-term use. The table below provides a quick comparison of the main classes.
| Medication Class | Mechanism of Action | Speed of Onset | Long-Term Use? | Risk of Dependence | Common Side Effects |
|---|---|---|---|---|---|
| Benzodiazepines | Enhances GABA, calming the central nervous system. | Fast (within minutes to hours). | Not Recommended. | High. | Drowsiness, confusion, dizziness. |
| SSRIs | Increases serotonin levels by blocking reuptake. | Slow (4-6 weeks). | Yes. | Low. | Nausea, sleep problems, sexual dysfunction. |
| SNRIs | Increases serotonin and norepinephrine levels. | Slow (4-6 weeks). | Yes. | Low. | Dizziness, weight gain, increased anxiety initially. |
| Buspirone | Affects serotonin and dopamine receptors. | Slow (1-2 weeks). | Yes. | Very Low. | Dizziness, headache, nausea. |
| Beta-Blockers | Blocks norepinephrine's effects on the body. | Relatively fast (within an hour). | Yes (off-label). | Very Low. | Dizziness, fatigue. |
Considerations and Precautions
Regardless of the medication, it is essential to work closely with a healthcare provider to find the most suitable treatment. It's also important to remember that medication is often most effective when combined with other forms of therapy, such as Cognitive Behavioral Therapy (CBT).
For benzodiazepines, in particular, patients must follow their doctor's orders precisely due to the risk of addiction and withdrawal symptoms upon abrupt discontinuation. For any antidepressant, the risk and benefits, especially for younger adults, must be carefully considered, and patients should be monitored closely for any behavioral changes. All medications have potential side effects, and what works well for one person might not work for another.

Conclusion
An anti-anxiety drug is formally called an anxiolytic, a class of medications that includes several different types, each with its own mechanism of action. The most common options are SSRIs and SNRIs for long-term management, and benzodiazepines for short-term or acute relief. Buspirone and beta-blockers also offer valuable alternatives for specific anxiety presentations. Choosing the right medication is a process that requires careful medical supervision and often works best when integrated into a broader treatment plan that includes psychotherapy and lifestyle adjustments. Never alter a medication regimen without first consulting a healthcare professional.
