Sodium oxybate is a medication primarily used to treat narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks. It helps improve nighttime sleep and reduces daytime sleepiness by acting on the central nervous system. This drug is typically taken in liquid form and is prescribed to be taken at night. Sodium oxybate is known for its potential for misuse, so it is classified as a controlled substance in many countries. Patients must follow their doctor's instructions carefully to ensure safe and effective use.
