In Parkinson's disease, what is the primary purpose of Carbidopa/Levodopa (Sinemet)?

Explanation:
The goal is to replace the dopamine that is lost in Parkinson's disease. Levodopa is a precursor that can cross the blood-brain barrier and is then converted to dopamine in the brain, helping to restore dopaminergic signaling and improve motor symptoms. Carbidopa sits outside the brain to inhibit peripheral conversion of levodopa to dopamine, which reduces side effects like nausea and allows more levodopa to reach the brain. This combination targets dopamine replenishment, not serotonin levels, inflammation, or acetylcholine.
