Summary

This study tested whether the drug solriamfetol (Sunosi) can reduce excessive sleepiness in people who start work between 3 and 6 AM. The trial planned to enroll 84 participants but was terminated early. Researchers measured sleepiness using a test that tracks how long people can stay awake, along with self-reported sleepiness scores.

Active substance

Solriamfetol (Sunosi) oral tablet

What this could lead to

If successful, this could provide a treatment option for excessive sleepiness in people who work very early morning shifts.

The trial was terminated early with only 84 participants, so results are limited. Solriamfetol may cause side effects like headache or nausea, and its long-term safety in shift workers is not fully known.
