Which of the following is a dopamine agonist used to treat restless legs syndrome?

• A. Pramipexole
• B. Gabapentin
• C. Clonazepam
• D. Ferritin measurement

Answer: (A)

Dopamine signaling is a common target in restless legs syndrome because increasing dopaminergic activity helps reduce the uncomfortable sensations and urge to move that worsen at rest and at night. Pramipexole is a dopamine agonist that stimulates D2-like receptors (especially D3) in the brain, and it’s specifically approved for treating RLS. By mimicking dopamine, it can lessen symptom severity and improve sleep. The other options don’t act as dopamine agonists. Gabapentin works on calcium channels and helps some nerve-related symptoms but isn’t a dopamine agonist. Clonazepam is a benzodiazepine used for sleep and anxiety, not to correct dopaminergic deficits. Ferritin measurement is a lab test; while iron status can influence RLS and iron supplementation may help if ferritin is low, it is not a therapy that acts as a dopamine agonist. Common considerations with dopamine agonists include augmentation (worsening of symptoms over time), daytime sleepiness, and other alertness issues, so they’re used with careful titration and monitoring.
