Carbidopa is indicated with [levodopa] for the treatment of symptoms of idiopathic Parkinson disease, postencephalitic parkinsonism and symptomatic parkinsonism followed by carbon monoxide or manganese intoxication. The combination therapy is administered for the reduction of [levodopa]-driven nausea and vomiting. The product of carbidopa should be used in patients where the combination therapy of carbidopa/[levodopa] provide less than the adequate daily dosage. As well carbidopa can be used in patients where the dosages of carbidopa and [levodopa] require individual titration.
FDA Label
When mixed with [levodopa], carbidopa inhibits the peripheral conversion of [levodopa] to dopamine and the decarboxylation of [oxitriptan] to serotonin by aromatic L-amino acid decarboxylase. This results in an increased amount of [levodopa] and [oxitriptan] available for transport to the central nervous system. Carbidopa also inhibits the metabolism of [levodopa] in the GI tract, thus, increasing the bioavailability of [levodopa]. The presence of additional units of circulating [levodopa] can increase the effectiveness of the still functional dopaminergic neurons and it has been shown to alleviate symptoms for a time. The action of carbidopa is very important as [levodopa] is able to cross the blood-brain barrier while dopamine cannot. Hence the administration of carbidopa is essential to prevent the transformation of external [levodopa] to dopamine before reaching the main action site in the brain. The coadministration of carbidopa with [levodopa] has been shown to increase the half-life of [levodopa] more than 1.5 times while increasing the plasma level and decreasing clearance. The combination therapy has also shown an increase of the recovery of [levodopa] in urine instead of dopamine which proves a reduced metabolism. This effect has been highly observed by a significant reduction in [levodopa] requirements and a significant reduction in the presence of side effects such as nausea. It has been observed that the effect of carbidopa is not dose-dependent.
Antiparkinson Agents
Agents used in the treatment of Parkinson's disease. The most commonly used drugs act on the dopaminergic system in the striatum and basal ganglia or are centrally acting muscarinic antagonists. (See all compounds classified as Antiparkinson Agents.)
Aromatic Amino Acid Decarboxylase Inhibitors
Compounds and drugs that block or inhibit the enzymatic action of AROMATIC AMINO ACID DECARBOXYLASES. Pharmaceutical agents in this category are used in conjunction with LEVODOPA in order to slow its metabolism. (See all compounds classified as Aromatic Amino Acid Decarboxylase Inhibitors.)
Dopamine Agents
Any drugs that are used for their effects on dopamine receptors, on the life cycle of dopamine, or on the survival of dopaminergic neurons. (See all compounds classified as Dopamine Agents.)
Absorption
When [levodopa]/carbidopa is administered orally, 40-70% of the administered dose is absorbed. Once absorbed, carbidopa shows bioavailability of 58%. A maximum concentration of 0.085 mcg/ml was achieved after 143 min with an AUC of 19.28 mcg.min/ml.
Route of Elimination
In animal studies, 66% of the administered dose of carbidopa was eliminated via the urine while 11% was found in feces. These studies were performed in humans and it was observed a urine excretion covering 50% of the administered dose.
Volume of Distribution
The volume of distribution reported for the combination therapy of carbidopa/[levodopa] is of 3.6 L/kg. However, carbidopa is widely distributed in the tissues, except in the brain. After one hour, carbidopa is found mainly in the kidney, lungs, small intestine and liver.
Clearance
The reported clearance rate for the combination therapy of [levodopa]/carbidopa is 51.7 L/h.
The loss of the hydrazine functional group (probably as molecular nitrogen) represents the major metabolic pathway for carbidopa. There are several metabolites of carbidopa metabolism including 3-(3,4-dihydroxyphenyl)-2-methylpropionic acid, 3-(4-hydroxy-3-methoxyphenyl)-2-methylpropionic acid, 3-(3-hydroxyphenyl)-2-methylpropionic acid, 3-(4-hydroxy-3-methoxyphenyl)-2-methyllactic acid, 3-(3-hydroxyphenyl)-2-methyllactic acid, and 3,4-dihydroxyphenylacetone (1,2).
The reported half-life of carbidopa is of approximately 107 minutes.
Carbidopa is an inhibitor of the DDC which in order, inhibits the peripheral metabolism of levodopa. DDC is very important in the biosynthesis of L-tryptophan to serotonin and the modification of L-DOPA to dopamine. DDC can be found in the body periphery and in the blood-brain barrier. The action of carbidopa is focused on peripheral DDC as this drug cannot cross the blood-brain barrier. Hence, it will prevent the metabolism of [levodopa] in the periphery but it will not have any activity on the generation of dopamine in the brain.
