What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: viloxazine extended-release capsules (SPN-812)
What this could lead to: If successful, this could confirm viloxazine as a safe long-term treatment option for managing ADHD symptoms in children and adolescents.
What could go wrong: This is an open-label extension study without a placebo group, so results may be less reliable. Long-term side effects are still being monitored.
