Levodopa is the active ingredient.
Carbidopa is a buffer to help prevent nausea (too much Levodopa triggers the brain into thinking the stomach has nausea, but it is all in the brain).

Hence 25/100 is common Carbidopa/Levodopa ratio. You can find 10/100 C/L formulations, but more often people have nausea issues.

Cabidopa by itself is available as a separate medication. USA trade name is Lydosyn. Often as 25mg, taken in addition with 25/100 Sinemet

Comtan just helps the levodopa stick around longer. So if C/L starts to wear off after four hours, your doc may add Comtan to see if C/L benefits last six hours.
