Carbidopa
Sinemet is the only carbidopa product on this shelf, pairing it with levodopa across three strength combinations to treat Parkinson’s Disease and Parkinsonism in the Neurology category.
Medicine containing Carbidopa
Key points
- Carbidopa is a decarboxylase inhibitor: it prevents much of levodopa from breaking down before it reaches the brain.
- This allows levodopa to address dopamine-related movement symptoms with less peripheral nausea and vomiting.
- Stopping carbidopa-levodopa suddenly can cause a serious syndrome with fever, rigidity, unusual movements and confusion.
What the strengths mean on the label
Sinemet pairs levodopa with carbidopa in three fixed combinations: 100 mg + 10 mg, 100 mg + 25 mg, and 250 mg + 25 mg. Carbidopa appears only inside combination tablets in this listing; there is no single-ingredient product. Stalevo adds entacapone to the same levodopa-carbidopa base, giving a third ingredient on top of the two already present in Sinemet.
