Evaluation of Foquest in Adults 65 Years and Older With ADHD

研究简介（原文）

This study is evaluating the safety and effectiveness of Foquest (multilayer-release methylphenidate), a once-daily extended-release medication for attention-deficit/hyperactivity disorder (ADHD), in adults aged 65 years and older. ADHD can persist into older age and is associated with reduced quality of life and difficulties with executive function. Foquest is currently approved in Canada for the treatment of ADHD in adults up to age 65, but there is very limited research on its use in older adults. People over 65 may respond differently to stimulant medications due to age-related changes in how the body processes drugs, other medical conditions, and increased sensitivity to cardiovascular side effects. This is an open-label study, meaning all participants will know they are receiving the study medication. There is no placebo group. Participants will take Foquest once daily for approximately 10 weeks, including a 6-week dose adjustment period, a 2-week maintenance period, and a 2-week follow-up period. The dose will start at 25 mg daily and may be increased weekly up to a maximum of 100 mg daily based on how well the participant responds and tolerates the medication. The main goal of the study is to measure changes in ADHD symptoms using a clinician-rated scale called the Adult ADHD Investigator Symptom Rating Scale (AISRS). The study will also assess changes in executive function, overall clinical improvement, and cardiovascular safety measures including blood pressure, heart rate, and electrocardiograms (ECGs). Safety will be closely monitored throughout the study, with enhanced cardiovascular monitoring during the first 6 weeks of treatment.
