A 7-yeаr-оld bоy is brоught to the pediаtriciаn for bad behavior. His teachers note that the child frequently has outbursts where he screams, yells, and occasionally throws objects at others.

Even on good days, the child is observed to be more irritable than the other children. The child's parents also note this behavior at home. The patient's vitals are unremarkable.

The teacher reports that he tests at grade level, but he seems to make careless mistakes on schoolwork and has trouble maintaining attention to instruction; he does not finish his homework, and he often loses his homework, pencils, and books. The boy is seen often fidgeting at his desk; he blurts out answers and has difficulty waiting his turn. The parents agree that they have seen similar traits at home for several years, such as forgetting to do daily activities and being easily distracted. They view him as a bright happy boy who is very active. He has had normal vision and hearing screenings. The father reports that he was very similar as a child and still struggles with focus and concentration as an adult, but he never received any help. The parents deny any major changes in the family situation. They would like medical help to improve their son's performance in school. The boy has been seen regularly for his well-child exams and has always met milestones and had normal exams. Today, he is quickly moving about the exam room; he looks at a book for a few moments, and he then looks to the window for a short while before interrupting his parents. Question: In addition to behavioral intervention, and assuming the parents agree to medication for their son, what medication is the most appropriate initial treatment?
