Which drug is primarily indicated for the management of ADHD?

Methylphenidate is primarily indicated for the management of attention-deficit/hyperactivity disorder (ADHD) as it is a central nervous system stimulant that helps increase attention and decrease impulsiveness and hyperactivity in patients diagnosed with ADHD. This medication is typically one of the first-line treatment options and has a well-established efficacy profile in both children and adults.

It works by influencing neurotransmitters in the brain, particularly dopamine and norepinephrine, which play crucial roles in attention and behavior regulation. Due to its mechanism of action and its history of effective use in a broad patient population, methylphenidate is often the go-to medication prescribed for ADHD.

Other drugs in the options may also be used for ADHD management, but they either serve as alternatives or have different mechanisms of action. For example, atomoxetine is a non-stimulant medication that targets norepinephrine reuptake and is often used when stimulants are not effective or are contraindicated. Dexmethylphenidate is a derivative of methylphenidate and is also effective for ADHD, but it is not as commonly used as the original methylphenidate formulation. Guanfacine, on the other hand, is primarily used to treat ADHD by affecting certain receptors
