Drug of choice for attention deficit disorder with hyperactivity is: September 2009
**Core Concept**
The underlying principle being tested is the management of **Attention Deficit Hyperactivity Disorder (ADHD)**, a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. **Methylphenidate** is a commonly used medication for this condition.
**Why the Correct Answer is Right**
**Methylphenidate** works by increasing the levels of **dopamine** and **norepinephrine** in the brain, improving attention and decreasing impulsivity and hyperactivity. It is a **central nervous system stimulant** and is considered the first-line treatment for ADHD due to its efficacy and relatively safe side effect profile.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it is not specified, and without the actual option text, we cannot determine its accuracy regarding ADHD treatment.
**Option B:** Incorrect because, like Option A, it lacks specific text to evaluate its relevance to ADHD management.
**Option C:** Incorrect for the same reason as Options A and B; the text is missing.
**Option D:** Also incorrect due to missing text, but typically, other options might include non-stimulant medications or other classes of drugs that are not first-line for ADHD.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **methylphenidate** has a quick onset of action and is available in various formulations, including immediate-release and extended-release forms, allowing for flexible dosing strategies tailored to the individual patient's needs.
**Correct Answer:** Correct Answer: D. Methylphenidate.
