MOA. Ropinirole is a non-ergoline dopamine agonist that has a higher specificity to D3 than to D2 and D4 subtypes of dopamine receptors. The drug has a moderate affinity for opioid receptors and has insignificant effects on D1, 5-hydroxytryptamine(1) (5-HT1), 5-HT2, benzodiazepine, gamma-aminobutyric acid (GABA), muscarinic, α,1-, α-2-, and β-adrenoreceptors. It is suggested that it stimulates the postsynaptic D2-type receptor found in the brain’s caudate putamen in Parkinson disease.
