Solriamfetol: First Global Approval

Solriamfetol (Sunosi™) is an orally active, selective dopamine and norepinephrine reuptake inhibitor that was recently approved in the USA as a treatment for excessive daytime sleepiness (hypersomnia) associated with narcolepsy and obstructive sleep apnoea (OSA). Norepinephrine and dopamine influence various physiologic functions, including sleep-wake regulation, and excessive sleepiness has been linked with dysregulation of dopaminergic and norepinephrine systems. This article summarizes the milestones in the development of solriamfetol leading to this first approval as a treatment for excessive daytime sleepiness associated with narcolepsy and OSA.
