The GABAB receptor agonist R-baclofen (R-BAC) improves non-rapid eye movement sleep quality and alleviates cataplexy in a mouse model of narcolepsy, a new study has shown. Interestingly, R-BAC was found to be more effective than γ-hydroxybutyrate (GHB), a drug that has already been approved by the FDA for the treatment of narcolepsy. The results indicate that R-BAC warrants further investigation as a possible therapy for narcolepsy and other sleep disorders.
