Which two classes of medications are commonly used to treat restless legs syndrome (RLS)?

• A. Dopaminergic agents and gabapentinoids
• B. Benzodiazepines and antidepressants
• C. Opioids and stimulants
• D. Antipsychotics and beta-blockers

Answer: (A)

Treating restless legs syndrome effectively relies on addressing the underlying neural signals that drive the uncomfortable sensations and urge to move. Dopaminergic agents stimulate dopamine receptors to correct the signaling imbalance that contributes to RLS, which often reduces legs’ sensations and the urge to move, especially at night. Gabapentinoids, such as gabapentin or pregabalin, dampen nerve excitability and help with both the uncomfortable sensations and the associated sleep disturbance. Together, these two classes are the mainstays used to relieve symptoms and improve sleep, either alone or in combination.

Other options don’t target the core symptoms as directly. Benzodiazepines and antidepressants may aid sleep but can worsen movement-related symptoms or be limited by side effects. Opioids and stimulants are typically reserved for severe or refractory cases. Antipsychotics and beta-blockers are not standard treatments for RLS and can worsen symptoms.
