Which of the following is a combination product used for ADHD?

• A. Lisdexamfetamine (Vyvanse)
• B. Adderall
• C. Methylphenidate (Ritalin)
• D. Paroxetine (Paxil)

Answer: (B)

The correct choice represents a combination product used for ADHD. Adderall is a combination medication that contains amphetamine and dextroamphetamine, which work together to help manage the symptoms of attention-deficit/hyperactivity disorder (ADHD). This dual-action approach allows it to effectively enhance focus and reduce impulsivity and hyperactivity, which are characteristic symptoms of ADHD.

In contrast, the other options either represent single-ingredient medications or are not specifically indicated for ADHD. Lisdexamfetamine, while effective in treating ADHD, is a single compound medication. Methylphenidate is also a single-ingredient medication that targets ADHD symptoms but is not a combination product. Paroxetine, on the other hand, is an antidepressant in the selective serotonin reuptake inhibitor class and is not indicated for the treatment of ADHD. Hence, Adderall stands out as the only choice that specifically combines two stimulant components for the management of ADHD.
