Sodium Oxybate and Sleep Apnea: A Clinical Case
AP-HP Hôpital Raymond Poincaré, Sleep Unit, Physiology Department, Versailles-St Quentin en Yvelines University, France
Sodium oxybate (GHB, Xyrem, Jazz Pharmaceuticals) is used to treat cataplexy in patients with narcolepsy. We report the case of a middle aged, normo-ponderal narcoleptic woman without risk factors who developed reversible sleep apnea and objective sleepiness when treated by sodium oxybate, with an apnea-hypopnea index (AHI) of 19.7 on sodium oxybate and AHI 4.8 without treatment. Despite a subjective improvement in vigilance, mean sleep latency on MWT decreased from 21 minutes to 8 minutes on sodium oxybate.
