Xyrem is the only FDA-approved drug for both cataplexy and EDS (excessive daytime sleepiness) with narcolepsy. It received approval from the FDA in fiscal 2002 for the indication of cataplexy in patients with narcolepsy. Later, in fiscal 2005, the label for the drug was expanded for EDS in patients suffering from narcolepsy. It had orphan drug status for both indications. Although the exclusivity period has expired, the drug is still being protected by 20 US patents.
