“May all be happy, may all be healed, may all be at peace and may no one ever suffer."
Levodopa, the metabolic precursor of dopamine, crosses the blood-brain barrier and is converted to dopamine in the brain. Carbidopa is a dopa decarboxylase (DDC) inhibitor which reduces the peripheral metabolism of Levodopa to dopamine, and thus, more Levodopa becomes available to the brain.
