Which drug corresponds to Pentobarbital?

• A. Morphine
• B. Pentobarbital
• C. Sufentanyl
• D. Nabilone

Answer: (B)

Pentobarbital is a barbiturate, a central nervous system depressant that enhances GABA activity at the GABA-A receptor, leading to sedation, hypnosis, and anticonvulsant effects. Among the options, this one is the barbiturate, while the others are different drug classes: morphine and sufentanyl are opioids, and nabilone is a synthetic cannabinoid. So the drug that corresponds to pentobarbital is the barbiturate itself, reflecting its distinct mechanism and therapeutic use compared with the opioid and cannabinoid options.
