Although dopamine does not readily cross the blood-brain barrier, its precursor, levodopa, does. Carbidopa is an inhibitor of amino acid decarboxylase (dopa decarboxylase), which is the enzyme present in both the peripheral and central tissue.9,10 Carbidopa only inhibits the peripheral conversion of levodopa.9,10 It does not inhibit the decarboxylase enzyme in the brain because it does not cross the blood brain barrier.4 This is important since inhibition of both central and peripheral amino acid decarboxylase would prevent levodopa from being converted to dopamine. What is carbidopa and levodopa? Carbidopa and levodopa is a combination medicine used to treat symptoms of Parkinson's disease, such as muscle stiffness, tremors, spasms, and poor muscle control. Parkinson's disease may be caused by low levels of a chemical called dopamine (DOE pa meen) in the brain. Because gastric AADC and COMT degrade levodopa, the drug is given with inhibitors of AADC(carbidopa or benserazide), and inhibitors of COMT will also enter clinical use.

APO-Levodopa/Carbidopa is a combination of levodopa, the metabolic precursor of dopamine, and carbidopa, an aromatic amino acid decarboxylase inhibitor, for the treatment of Parkinson's disease and syndrome. Symptoms of Parkinson's disease have been related to depletion of dopamine in the corpus striatum of the brain. Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. The plasma half-life of levodopa is about 50 minutes, without carbidopa.
