Biochem/physiol Actions

Ropinirole hydrochloride is effectively used to treat early and late Parkinson′s disease.
An agonist at the D2 and D3 dopamine receptor subtypes, binding with higher affinity to D3 than to D2 or D4. It has negligible effect on D1-receptors. It has medium in vitro affinity to opioid receptors. Ropinirole is said to have virtually no affinity to 5-HT1, 5-HT2, benzodiazepine, GABA, muscarinic, α1-, α2-, and β-adrenoreceptors. Used as antiparkinsonian drug.
Selective D2 dopamine receptor agonist, antiparkinsonian
