Orally administered sodium oxybate for the treatment of narcolepsy

Narcolepsy-cataplexy: how does recent understanding help in evaluation and treatment

Narcolepsy is a substantially disabling disease with profound physical, mental, and social effects. The burden on patients is compounded by delayed and missed diagnoses and by the subsequent undertreatment of narcolepsy and associated symptoms such as cataplexy. The recent advances in the elucidation of the genetics of canine narcolepsy and the pathophysiologic role of hypocretin, in animals and humans, enhances current diagnostic capability and will provide better treatment modalities in the future. The varied symptoms of narcolepsy are challenging to manage and may require treatment with a combination of agents. The recent development of a markedly enhanced characterization of sodium oxybate in the treatment of the excessive daytime sleepiness, nocturnal sleep fragmentation, and cataplexy of narcolepsy offers the potential of treating multiple symptoms simultaneously and marks a dramatic advance in the treatment of narcolepsy.
