Parkinson’s disease

Carbidopa is a peripheral dopa-decarboxylase inhibitor which exhibits a distinct pharmacological activity only when given in combination with levodopa. Carbidopa inhibits the peripheral decarboxylation of levodopa to dopamine. As, unlike levodopa, carbidopa does not cross the blood-brain barrier, effective brain concentrations of dopamine are produced with lower doses of levodopa.

In the treatment of parkinsonism carbidopa is administered in combination with levodopa to allow a lower dosage of the latter, a more rapid onset of a response, and a mitigation of adverse effects.
