Adult Attention Deficit Hyperactivity Disorder
Conditions
Brief summary
This is a single-site study. One purpose of this trial is to extend the safety and efficacy evidence basis for Azstarys in adults with ADHD. This open-label, treatment study will examine the efficacy of Azstarys on ADHD symptoms using the AISRS 18-item total score on the AISRS-expanded; the Adult ADHD Investigator Symptom Rating Scale. The investigators will also examine Executive Function later in the day (early evening, about 12 hours after first morning dosing).
Interventions
Azstarys capsules for once-daily oral use for three weeks. Flexible dose starting at 39.2 mg serd-mph/7.8 mg d-mph and moving up to 52.3 mg serd-mph/10.4 mg d-mph.
