Which term describes drugs that act as CNS depressants and are used to calm patients?

• A. Sedative Hypnotics
• B. Opioids
• C. Stimulants
• D. Sympathomimetics

Answer: (A)

Sedative-hypnotics describe drugs that depress central nervous system activity. At lower doses they produce calmness and reduced anxiety (sedation), and at higher doses they can induce sleep (hypnosis). This combination makes them the typical choice for calming patients or premedicating before procedures. They often work by enhancing GABAergic inhibition in the brain, with classes like benzodiazepines and barbiturates as common examples.

Opioids primarily provide analgesia and can cause drowsiness, but their main role isn’t calming a patient in the sense of anxiety reduction. Stimulants increase CNS activity and alertness, which is opposite of calming, and sympathomimetics activate the sympathetic fight-or-flight response, also not calming.
