Which term names sedatives with effects similar to alcohol intoxication?

• A. Benzodiazepines
• B. Sedatives
• C. Barbiturates
• D. Hypnotics

Answer: (C)

The main idea is how certain CNS depressants produce alcohol-like intoxication. Barbiturates are a class of sedative-hypnotics that produce strong CNS depression similar to alcohol. They work by enhancing the activity of the GABA-A receptor, increasing the duration of chloride channel opening, which deepens inhibitory effects in the brain. That translates into the classic signs of intoxication: drowsiness, slowed speech and reflexes, impaired coordination and judgment, and in higher doses, breathing suppression and even coma. Because of their potency and narrow safety margin, barbiturates have long been associated with alcohol-like intoxication profiles and have a history of use as sedatives and sleep aids. While other CNS depressants, like benzodiazepines, can also cause alcohol-like effects, the term that names sedatives with this specific intoxication pattern is barbiturates, rather than the broader categories of hypnotics or sedatives.
