The Advisory Council On The Misuse Of Drugs Decision Regarding Sunosi Being Categorised As A Controlled Drug


The ACMD (Advisory Council on the Advisory Council on the Misuse of Drugs) and MHRA (Medicines and Healthcare products Regulatory Agency) has evaluated the risk of substance abuse and physical dependency of the medicine Sunosi (Solriamfetol). Sunosi is a once-daily prescription medicine used to improve wakefulness in adults with excessive daytime sleepiness due to obstructive sleep apnoea or narcolepsy.


What Does “Improved Wakefulness” Mean?

Improvements in wakefulness were determined by the Maintenance of Wakefulness Test (MWT).

The MWT is a standard test used to measure a person’s ability to stay awake during the daytime in a darkened, quiet environment. People are instructed to remain awake as long as possible throughout a series of 40-minute sessions that are spaced out across the day.

The MWT calculates the average time it takes for a person to fall asleep during each of these sessions. Individuals who have improvements in wakefulness are able to stay awake longer during the MWT.
