Not every anxiolytic is a benzodiazepine, Z-drug, or barbiturate. This covers the rest: buspirone (slow-onset, non-sedating, daily), hydroxyzine (a sedating antihistamine for short-term anxiety), beta blockers (for physical symptoms of situational anxiety), and the reminder that SSRIs/SNRIs and gabapentinoids also treat anxiety despite living under other categories. None of these give instant relief like a benzodiazepine, and medication is only part of the picture — psychotherapy belongs alongside or before it.
The college version
Buspirone
Buspirone is a partial agonist at the serotonin 5-HT1A receptor, mechanistically distinct from benzodiazepines, which act on GABA-A receptors. Because it does not touch the GABA system, it produces no meaningful sedation, no euphoria, no muscle relaxation, and no physical dependence or withdrawal. It carries no abuse potential, making it attractive for patients with a substance use history or for long-term generalized anxiety disorder management.
The key limitation is onset: buspirone must be taken on a fixed, scheduled basis, and full effect typically takes weeks to build, similar to an antidepressant. It has no role as a rescue or as-needed drug — an extra dose during an anxiety spike gives no noticeable relief, and patients expecting fast relief often conclude it "doesn't work" and stop prematurely. Education must stress consistent daily dosing regardless of daily symptoms. Buspirone should not be combined with MAO inhibitors, and caution is warranted with other serotonergic agents due to additive serotonin effects.
Hydroxyzine
Hydroxyzine is a first-generation antihistamine (H1 antagonist) with strong CNS-depressant and anticholinergic properties, giving it useful sedative-anxiolytic effects. Unlike buspirone, its onset is fast, suiting short-term or situational anxiety, procedural anxiety, or use during benzodiazepine tapers. Downsides mirror other antihistamines: drowsiness, dry mouth, blurred vision, constipation, and impaired psychomotor performance, so patients should be cautioned about driving. It is not intended for long-term daily control.
Beta Blockers
Beta blockers such as propranolol act on peripheral beta-adrenergic receptors, blunting somatic anxiety symptoms — tachycardia, tremor, sweating, a pounding heartbeat — rather than the psychological experience itself. This suits performance anxiety (public speaking, auditions, exams), taken before the triggering event. They do not address rumination, worry, or panic-level distress, and are not appropriate as monotherapy for generalized anxiety disorder. Caution applies with asthma, reactive airway disease, bradycardia, or cardiac conduction abnormalities.
SSRIs, SNRIs, and Gabapentinoids
Although classified under antidepressants, SSRIs and SNRIs are the guideline-preferred first-line treatment for generalized anxiety disorder and panic disorder, valued for sustained efficacy and low abuse potential despite an onset measured in weeks. Gabapentinoids (gabapentin, pregabalin) modulate calcium channels to reduce neuronal excitability and are used in select cases — alcohol-associated anxiety, treatment-resistant presentations, or adjuncts — though not universal first-line agents.
The Role of Psychotherapy
Cognitive behavioral therapy (CBT) and related psychotherapies target the thought patterns and avoidance behaviors that sustain anxiety disorders, producing durable, skill-based improvement without pharmacologic risk. Guidelines place psychotherapy alongside medication, and often ahead of it for mild-to-moderate cases, because therapy addresses root drivers rather than only neurochemistry.
Eli explains
The same idea, in plain words
Explain it like I’m 10
Anxiety medicines are like tools for a leaky roof. A benzodiazepine is an umbrella you pop open the second it rains — instant relief. Buspirone is patching the roof: you work on it daily, and it takes weeks before the leak stops, so opening it the moment it rains does nothing. Hydroxyzine is a raincoat grabbed fast for a short walk — useful now, not worn all day. Beta blockers are a towel that only dries the puddle on the floor — they calm your racing heart but don't fix why it's raining in your head. Therapy fixes the roof itself, so eventually you need fewer tools.

2 review questions from the chapter. Try each one, then open the answer.
A patient starts buspirone and after three days calls the clinic saying "it isn't working, I still feel anxious." What should the nurse explain about why this is expected?
Show answer
Buspirone needs weeks of steady, scheduled use before it builds up its full effect
The nurse should explain that buspirone is not a rescue medication and will not work if taken only when anxious; it must be taken every day as prescribed, and noticeable improvement typically takes several weeks, so three days is far too soon to judge whether it is working.
Explain why a prescriber might recommend cognitive behavioral therapy alongside, or even before, starting medication for a patient with mild generalized anxiety disorder.
Show answer
CBT treats the root thought and behavior patterns driving the anxiety
For mild cases, therapy can produce lasting improvement without the delayed onset, side effects, or ongoing medication commitment that drugs involve, so guidelines often favor trying or combining it before relying on medication alone.
