How methylphenidate works in adults with ADHD with or without obesity
Part of Hormones & metabolism, Mental health clinical trials.
This study looks at how the body processes methylphenidate (Ritalin) in adults with ADHD, comparing people with obesity (BMI 30 or higher) to those without. It aims to find out if weight affects the medication levels, which could help doctors adjust doses for better treatment.
