Which medication is indicated for the treatment of attention deficit hyperactivity disorder (ADHD)?

Methylphenidate is indicated for the treatment of attention deficit hyperactivity disorder (ADHD) because it is a central nervous system stimulant that helps to increase attention and decrease impulsiveness and hyperactivity in patients with this condition. It works by increasing the levels of certain neurotransmitters in the brain, specifically dopamine and norepinephrine, which are essential for focus and attention.

Medications like sertraline and duloxetine are primarily used as antidepressants and are not typically indicated for ADHD. They may be helpful in treating coexisting conditions such as anxiety or depression but do not directly address the core symptoms of ADHD. Clozapine is an antipsychotic medication used to treat schizophrenia and is not associated with the treatment of ADHD. Thus, methylphenidate is the most appropriate choice for managing ADHD symptoms.
