Abstract
The invention relates to modified release oral formulations of therapeutic agents, including gamma hydroxybutyrate (GHB), paracetamol, codeine or oxycodone, which are resistant to alcohol induced dose dumping. Provided are formulations that have improved resistance to rapid release of the active ingredient in the presence of increasing amounts of alcohol. Also provided are formulations that can reduce or prevent the release of the active ingredient following exposure to alcohol-containing media. The invention also relates to methods of making the formulations, and methods of their use for the treatment of sleep disorders such as apnea, sleep time disturbances, narcolepsy, cataplexy, sleep paralysis, hypnagogic hallucination, sleep arousal, insomnia, and nocturnal myoclonus.
