Development and Mechanism of Action of Carbidopa Levodopa

Carbidopa Levodopa, known as CineMet, is a crucial medication for Parkinson's disease. The key pathology in Parkinson's involves a decrease in brain dopamine due to the loss of cells in the substantia nigra. Initially, directly giving dopamine to patients was ineffective since it does not cross the blood-brain barrier. However, researchers found that administering DOPA, a precursor to dopamine, allowed it to be converted to dopamine in the brain. Despite positive results, the initial formulation caused neutropenia issues, leading to further refinement.
