Ropinirole is a non-ergoline dopamine agonist. Ropinirole has the highest affinity at the D3 receptors, which are concentrated in the limbic areas of the brain and may be responsible for some of the neuropsychiatric effects. The exact mechanism of action of ropinirole as a treatment for Parkinson’s disease is unknown, however, it is believed to be related to its ability to selectively stimulate dopamine D2 receptors within the caudate-putamen system in the brain. This system affects body movement. Negligible affinity is seen for ropinirole at α2 adrenoreceptors in the periphery and 5HT-1 receptor. Ropinirole has no affinity at the D1-like receptors, benzodiazepine or GABA receptors. The precise mechanism of action of ropinirole as a treatment for Restless Legs Syndrome is unknown, however, it is believed to be related to its ability to stimulate dopamine receptors.
Because Ropinirole is a dopamine agonist, it is possible that dopamine antagonists such as neuroleptics (phenothiazines, butyrophenones, thioxanthenes) or metodopramide may reduce the efficacy of Ropinirole.
The most common side effects of Ropinirole include fainting, drowsiness, hallucinations, dizziness, nausea or vomiting, uncontrolled sudden movements, leg swelling, fatigue, confusion, headache, upset stomach, abdominal pain or discomfort, increased sweating etc.
Pregnancy category C. There is no adequate and well-controlled studies in pregnant women. It should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus. Ropinirole inhibits prolactin secretion in human and could potentially inhibit lactation.
Patients treated with Ropinirole have reported falling asleep while engaged in activities of daily living. Dopamine agonists in clinical trials and clinical experience appear to impair the systemic regulation of blood pressure, with resulting orthostatic hypotension.
