Solriamfetol for the treatment of daytime sleepiness in obstructive sleep apnea. Expert review of respiratory medicine Abad, V. C., Guilleminault, C. 2018


INTRODUCTION: Obstructive sleep apnea (OSA) is highly prevalent and constitutes a major health hazard. Current pharmacotherapy is ineffective in correcting sleep-disordered breathing and is used adjunctively to address residual sleepiness. A new drug, solriamfetol, a selective norepinephrine-dopamine reuptake inhibitor, is the first drug of its class that is being considered by the US Food and Drug Administration (FDA) to treat excessive sleepiness in OSA and narcolepsy patients. Areas Covered: This review covers drug chemistry, pharmacodynamics, pharmacokinetics, and metabolism of solriamfetol. Results of three Phase 3 trials, Treatment of OSA and Narcolepsy Excessive Sleepiness (TONES 3, 4, 5), relevant to OSA patients are summarized. Published abstracts/articles and a 2017 Jazz Investor Presentation provided data. Databases searched included PubMed, Google Scholar, Lexi-Comp, Scopus, Science, and Ovid. Expert Commentary: Solriamfetol shows promise as adjunctive therapy in OSA. It is well tolerated and effective in reducing sleepiness and is an alternative to modafinil or armodafinil. Unlike stimulants like methylphenidate or dextroamphetamine, it does not have cardiac effects, rebound hypersomnia, or withdrawal effects.
