Solriamfetol

Solriamfetol, sold under the brand name Sunosi, is a wakefulness-promoting medication used in the treatment of excessive sleepiness related to narcolepsy and sleep apnea. It is taken by mouth.

Common side effects of solriamfetol include headache, nausea, anxiety, and trouble sleeping. It is a norepinephrine–dopamine reuptake inhibitor (NDRI) and is thought to work by increasing levels of the neurotransmittersnorepinephrine and dopamine in the brain. Solriamfetol has also been found to act as a TAAR1agonist, an action that may also be involved in its effects.

The drug was discovered by a subsidiary of SK Group, which licensed rights outside of eleven countries in Asia to Aerial Pharma in 2011. In addition to its approved indication of excessive sleepiness, solriamfetol is under development for certain other uses including the treatment of attention deficit hyperactivity disorder (ADHD), binge eating disorder, and circadian rhythm sleep disorders. The drug is also a potential designer drug.
