Which agent is used to improve nighttime sleep and daytime symptoms in narcolepsy?

• A. Sodium oxybate
• B. Methylphenidate
• C. Modafinil
• D. Selegiline

Answer: (A)

The key idea is that the therapy which best addresses narcolepsy by improving both nighttime sleep and daytime symptoms is sodium oxybate. Taken at night in two doses, it consolidates nocturnal sleep and reduces sleep fragmentation, which translates into less daytime sleepiness. It also helps reduce cataplexy, further boosting daytime functioning. This dual effect makes it more comprehensive than agents that only promote wakefulness during the day. Medications like methylphenidate or modafinil improve daytime alertness but do not correct the disturbed night sleep, and may even worsen sleep architecture if used improperly. Selegiline isn’t a standard narcolepsy therapy. So sodium oxybate stands out because it improves the night’s sleep quality and the daytime symptoms, addressing the condition more holistically.
