Which hypnotic/rest agent is noted for having a long half-life and is used for long duration rest?

• A. Zaleplon (Sonata)
• B. Temazepam (Restoril)
• C. Dexedrine
• D. Zolpidem (Ambien)

Answer: (B)

When choosing a hypnotic based on how long it will help you sleep, the key is how long the drug stays active in the body, i.e., its half-life. Longer-acting agents tend to sustain sleep through the night, while very short-acting ones are better for falling asleep but may not prevent early awakenings. Zaleplon and zolpidem are non-benzodiazepine hypnotics with short half-lives, so they’re more suited to helping you fall asleep rather than staying asleep all night. Dexedrine is a stimulant, not a hypnotic. Temazepam is a benzodiazepine with a longer half-life than the Z-drugs, providing a more prolonged effect that supports longer duration rest, which is why it fits the “long half-life and long duration rest” description best among these options. Note that longer action can mean more next-day sedation, so this choice balances duration with potential daytime effects.
