Sleep & anxiety agents
Non-benzodiazepine options
Insomnia and generalized anxiety, without using a benzodiazepine.
Zolpidem acts on the same receptor family as benzodiazepines but more selectively; buspirone works on serotonin; melatonin follows the body's own sleep signal.

What to know for the exam
- check_circleZolpidem is a Schedule IV controlled substance.
- check_circleBuspirone is not controlled and is not habit-forming.
- check_circleBuspirone takes weeks to work, so it isn't useful for sudden anxiety.
- check_circleMelatonin is sold as a dietary supplement, not an approved drug.
Zolpidem carries a boxed warning about complex sleep behaviours — sleepwalking, sleep-driving — which mean stopping the drug.
Buspirone versus a benzodiazepine is the standard 'not controlled, not immediate' contrast.
