I have RLS and take Ropinirole. It works very well, I can finally sleep through the night.
Ropinirole use to treat Parkinsonism and RLS which act as a D2, D3, and D4 dopamine receptoragonist with highest affinity for D2. It is weakly active at the 5-HT2, and α2 receptors and is said to have virtually no affinity for the 5-HT1, GABA, mAChRs, α1, and β-adrenoreceptors
