Mechanism of action Carbidopa is an inhibitor of the DDC which in order, inhibits the peripheral metabolism of levodopa. 3 DDC is very important in the biosynthesis of L-tryptophan to serotonin and the modification of L-DOPA to dopamine. 4


Carbidopa is a peripheral dopa decarboxylase inhibitor that is used as an adjunct to levodopa administration to prevent peripheral biosynthesis of levodopa to dopamine, thereby reducing peripheral side effects.

Parkinson's disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. 2017-09-01 Antimuscarinics, by slowing GI transit, may also decrease levodopa bioavailability; however, this mechanism appears to be of modest clinical significance.

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.

The past half-century has confirmed that the typical l-dopa-treated patient gains improvement for most Parkinsonian features, presumably by conversion of this amino acid into dopamine in the striatum. However, fundamental questions remain as to its full mechanism of action and how adverse reactions evolve. Common medications used to treat Parkinson’s disease are carbidopa/levodopa, selegiline, and amantadine.

The Applicant has completed module 1.7.1 (report addressing the possible similarity with Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. Mechanism of Action . Levodopa . Current evidence indicates that symptoms of Parkinson’s disease are related to depletion of Carbidopa (Lodosyn) is a drug given to people with Parkinson's disease in order to inhibit peripheral metabolism of levodopa. This property is significant in that it allows a greater proportion of peripheral levodopa to cross the blood–brain barrier for central nervous system effect. Carbidopa prevents the breakdown of levodopa outside the brain. In the brain, levodopa is broken down into dopamine, its active form.
