NIDA sedatives examples benzodiazepines barbiturates
Examples of sedatives include:
- Benzodiazepines: diazepam, lorazepam, alprazolam, midazolam, temazepam
- Barbiturates: phenobarbital, pentobarbital, secobarbital
- Other sedative-hypnotics: zolpidem, zopiclone/eszopiclone, zaleplon
- Used in medical procedures or intensive care: propofol, dexmedetomidine
They reduce anxiety and/or induce sleep, but can cause excessive drowsiness and slowed breathing, especially when combined with alcohol, opioids, or other sedating medicines. Benzodiazepines and barbiturates are classic sedative-hypnotics. [Katzung's Basic and Clinical Pharmacology, 16th ed., sedation section]

sedative versus hypnotic difference pharmacology examples
| Feature | Sedative | Hypnotic |
|---|---|---|
| Main effect | Calms the patient, reduces anxiety and agitation | Produces or helps initiate sleep |
| Typical dose | Lower dose | Usually a higher dose of the same or a similar drug |
| Common use | Anxiety, pre-procedure calming, ICU/procedural sedation | Short-term treatment of insomnia |
| Examples | Diazepam, lorazepam, midazolam, dexmedetomidine | Zolpidem, zaleplon, eszopiclone, temazepam, ramelteon |
The distinction is mainly dose and intended effect, not always the medication itself. Many drugs lie on a continuum:
- Lorazepam at a lower dose may be used for calming anxiety or sedation; at a larger bedtime dose it may promote sleep.
- Temazepam is a benzodiazepine mainly used as a hypnotic for insomnia.
- Zolpidem is mainly a hypnotic, intended to induce sleep.
- Midazolam is mainly used as a sedative for procedures.
So, sedative = calming, whereas hypnotic = sleep-inducing. Many medicines are called sedative-hypnotics because they can do both. Kaplan & Sadock’s Comprehensive Textbook of Psychiatry describes these effects as a continuum, and Goodman & Gilman’s The Pharmacological Basis of Therapeutics includes benzodiazepines, Z-drugs, and barbiturates in this group.
