Key takeaways
Ropinirole (generic name) and Stalevo (carbidopa/levodopa/entacapone) are both used to treat Parkinson's disease (PD), but they work differently. Ropinirole is a dopamine agonist that mimics dopamine in the brain and is also used for restless legs syndrome (RLS). It comes in immediate-release and extended-release tablets, and common side effects include nausea, sleepiness, and dizziness. Stalevo, on the other hand, is a combination of three medications: carbidopa, levodopa, and entacapone. Levodopa replaces dopamine, while carbidopa and entacapone help prevent levodopa from breaking down before it reaches the brain. Stalevo is specifically for PD and helps reduce "off" periods when symptoms return. It can cause side effects like involuntary movements, nausea, and diarrhea. Both medications are available in generic forms, but Stalevo combines three drugs into one pill for convenience, whereas ropinirole is a single medication.
