Following drugs are used in treatment of ADHD –
**Core Concept**
The correct answer involves understanding the pharmacological management of Attention Deficit Hyperactivity Disorder (ADHD), which includes a class of medications known as central nervous system stimulants. These medications enhance the effects of dopamine and norepinephrine in the brain, improving focus, attention, and impulse control.
**Why the Correct Answer is Right**
The correct answer is a type of central nervous system stimulant that works by increasing the synthesis and release of dopamine and norepinephrine in the prefrontal cortex, thereby improving attention and reducing impulsivity. This is achieved through the inhibition of the reuptake of these neurotransmitters by the presynaptic neuron, allowing them to remain in the synaptic cleft for a longer period. This mechanism is mediated by the enzyme dopamine transporter (DAT) and norepinephrine transporter (NET).
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it is not a common medication used in the treatment of ADHD.
**Option B:** This option is incorrect as it is an antipsychotic medication primarily used in the treatment of schizophrenia, not ADHD.
**Option C:** This option is incorrect as it is not a medication specifically approved for the treatment of ADHD.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that central nervous system stimulants are the first-line treatment for ADHD, and they work by increasing dopamine and norepinephrine levels in the prefrontal cortex. It's also essential to note that these medications can have potential side effects, such as increased heart rate and blood pressure, and should be used under close medical supervision.
**Correct Answer: C. Methylphenidate**
