Sedative hypnotics are classified as which type of drugs?

• A. Antidepressants
• B. CNS Depressants
• C. Stimulants
• D. Opioids

Answer: (B)

Sedative hypnotics slow brain activity to produce calmness or sleep, so they’re classified as CNS depressants. They include benzodiazepines, barbiturates, and non-benzodiazepine hypnotics; their primary action is enhancing GABA inhibition in the brain, which increases chloride influx through GABA-A receptors and dampens arousal circuits. This depressant effect on the central nervous system distinguishes them from antidepressants, which affect mood-related neurotransmitters but aren’t primarily sedative-hypnotics, and from stimulants, which increase CNS activity. Opioids can cause sedation as a side effect, but they form a distinct class with different pharmacology and aren’t labeled sedative hypnotics.
