Key takeaways
Sinemet (carbidopa/levodopa) and pramipexole (Mirapex ER) are both used to treat Parkinson's disease (PD), but they work differently and have different dosing schedules. Sinemet is a combination of carbidopa and levodopa, where levodopa is converted into dopamine in the brain, and carbidopa prevents levodopa from breaking down before it reaches the brain. Pramipexole, on the other hand, is a dopamine agonist that mimics dopamine's effects in the brain. Sinemet is taken multiple times a day, while pramipexole's immediate-release form is also taken three times a day, but its extended-release form is taken once daily. Sinemet can cause dark-colored urine, saliva, and sweat, while pramipexole can lead to compulsive behaviors like binge eating and gambling. Both medications can cause sleepiness and should not be stopped abruptly without consulting your healthcare provider. Sinemet is available in various forms, including immediate-release and extended-release tablets, while pramipexole is only available as a tablet.
