Ropinirole Pharmacology

Ropinirole (Requip) is a dopamine agonist that can be used in Parkinson's disease and Restless Legs Syndrome. Dopamine agonists like ropinirole can worsen psychiatric symptoms in some patients by causing hallucinations, and obsessive/compulsive symptoms. Nausea, vomiting, hypotension, and fatigue are the most common adverse effects of ropinirole. Ropinirole has drug interactions with antipsychotics and CYP1A2 inhibitors. I discuss these in greater detail in this podcast episode.
