(carbidopa and levodopa orally disintegrating tablets)
PARCOPA® (carbidopa and levodopa orally disintegrating tablets) is a combination of
carbidopa and levodopa for the treatment of Parkinson’s disease and syndrome.
PARCOPA® is an orally administered formulation of carbidopa and levodopa which
rapidly disintegrates on the tongue and does not require water to aid dissolution or
Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.24. It is designated chemically as (–)-L-α-hydrazino-α-methyl-ß-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O, and its structural formula is:
Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.23.
Levodopa, an aromatic amino acid, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 197.2. It is designated chemically as (–)-L-α-amino-ß-(3,4-dihydroxybenzene) propanoic acid. Its empirical formula is C9H11NO4, and its structural formula is:
PARCOPA® is supplied as tablets in three strengths: PARCOPA® 25/100, containing 25 mg of carbidopa and 100 mg of levodopa. PARCOPA® 10/100, containing 10 mg of carbidopa and 100 mg of levodopa. PARCOPA® 25/250, containing 25 mg of carbidopa and 250 mg of levodopa.
Inactive ingredients are aspartame, citric acid, crospovidone, magnesium stearate, mannitol, microcrystalline cellulose, natural and artificial mint flavor and sodium
bicarbonate. PARCOPA® 10/100 and 25/250 also contain FD&C blue #2 HT aluminum lake. PARCOPA® 25/100 also contains yellow 10 iron oxide.
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.
Symptomatic treatments, such as levodopa therapies, may permit the patient better
Mechanism of Action
Current evidence indicates that symptoms of Parkinson’s disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson’s disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson’s disease.
When levodopa is administered orally it is rapidly decarboxylated to dopamine in
extracerebral tissues so that only a small portion of a given dose is transported unchanged
to the central nervous system. For this reason, large doses of levodopa are required for
adequate therapeutic effect and these may often be accompanied by nausea and other
adverse reactions, some of which are attributable to dopamine formed in extracerebral
Since levodopa competes with certain amino acids for transport across the gut wall, the absorption of levodopa may be impaired in some patients on a high protein diet.
Carbidopa inhibits decarboxylation of peripheral levodopa. It does not cross the blood-brain barrier and does not affect the metabolism of levodopa within the central nervous system.
The incidence of levodopa-induced nausea and vomiting is less with carbidopa and levodopa than with levodopa. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration.
Since its decarboxylase inhibiting activity is limited to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain.
Carbidopa reduces the amount of levodopa required to produce a given response by about 75 percent 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. When carbidopa and levodopa are administered together, the half-life of levodopa is increased to about 1.5 hours. At steady state, the bioavailability of carbidopa from carbidopa and levodopa tablets is approximately 99% relative to the concomitant administration of carbidopa and levodopa.
In clinical pharmacologic studies, simultaneous administration of carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine than administration of the two drugs at separate times.
Pyridoxine hydrochloride (vitamin B6), in oral doses of 10 mg to 25 mg, may reverse the effects of levodopa by increasing the rate of aromatic amino acid decarboxylation. Carbidopa inhibits this action of pyridoxine; therefore, PARCOPA® can be given to patients receiving supplemental pyridoxine (vitamin B6).
INDICATIONS AND USAGE
PARCOPA® is indicated in the treatment of the symptoms of idiopathic Parkinson’s
disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic
parkinsonism which may follow injury to the nervous system by carbon monoxide
intoxication and/or manganese intoxication. PARCOPA® is indicated in these conditions
to permit the administration of lower doses of levodopa with reduced nausea and
vomiting, with more rapid dosage titration, with a somewhat smoother response, and with
supplemental pyridoxine (vitamin B6).
In some patients, a somewhat smoother antiparkinsonian effect results from therapy with carbidopa and levodopa than with levodopa. However, patients with markedly irregular (“on-off”) responses to levodopa have not been shown to benefit from carbidopa and levodopa therapy.
Although the administration of carbidopa permits control of parkinsonism and Parkinson’s disease with much lower doses of levodopa, there is no conclusive evidence at present that this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to levodopa.
Certain patients who responded poorly to levodopa have improved when carbidopa and levodopa was substituted. This is most likely due to decreased peripheral decarboxylation of levodopa which results from administration of carbidopa rather than to a primary effect of carbidopa on the nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa in parkinsonian syndromes.
In considering whether to give PARCOPA® to patients already on levodopa who have nausea and/or vomiting, the practitioner should be aware that, while many patients may be expected to improve, some do not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing carbidopa and levodopa with levodopa, about half of the patients with nausea and/or vomiting on levodopa improved spontaneously despite being retained on the same dose of levodopa during the controlled portion of the trial.
Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with
PARCOPA®. These inhibitors must be discontinued at least two weeks prior to initiating
therapy with PARCOPA®. PARCOPA® may be administered concomitantly with the
manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B
(e.g., selegiline HCl) (See PRECAUTIONS, Drug Interactions
PARCOPA® is contraindicated in patients with known hypersensitivity to any component of this drug, and in patients with narrow-angle glaucoma.
Because levodopa may activate a malignant melanoma, PARCOPA® should not be used in patients with suspicious, undiagnosed skin lesions or a history of melanoma.
When PARCOPA® (carbidopa and levodopa orally disintegrating tablets) is to be
given to patients who are being treated with levodopa, levodopa must be
discontinued at least twelve hours before therapy with PARCOPA® (carbidopa and
levodopa orally disintegrating tablets) is started. In order to reduce adverse
reactions, it is necessary to individualize therapy. See DOSAGE AND
ADMINISTRATION section before initiating therapy.
The addition of carbidopa with levodopa in the form of PARCOPA® reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, carbidopa does not decrease the adverse reactions due to the central effects of levodopa. Because carbidopa permits more levodopa to reach the brain and more dopamine to be formed, certain adverse CNS effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with PARCOPA® than with levodopa alone.
Levodopa alone, as well as PARCOPA®, is associated with dyskinesias. The occurrence of dyskinesias may require dosage reduction.
As with levodopa, PARCOPA® may cause mental disturbances. These reactions are thought to be due to increased brain dopamine following administration of levodopa. All patients should be observed carefully for the development of depression with concomitant suicidal tendencies. Patients with past or current psychoses should be treated with caution.
PARCOPA® should be administered cautiously to patients with severe cardiovascular or pulmonary disease, bronchial asthma, renal, hepatic or endocrine disease.
As with levodopa, care should be exercised in administering PARCOPA® to patients with a history of myocardial infarction who have residual atrial, nodal, or ventricular arrhythmias. In such patients, cardiac function should be monitored with particular care during the period of initial dosage adjustment, in a facility with provisions for intensive cardiac care.
As with levodopa, treatment with PARCOPA® may increase the possibility of upper gastrointestinal hemorrhage in patients with a history of peptic ulcer.
Neuroleptic Malignant Syndrome (NMS):
Sporadic cases of a symptom complex
resembling NMS have been reported in association with dose reductions or withdrawal of
therapy with carbidopa and levodopa. Therefore, patients should be observed carefully
when the dosage of PARCOPA® is reduced abruptly or discontinued, especially if the
patient is receiving neuroleptics.
NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin have been reported.
The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology.
The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS, however, their effectiveness has not been demonstrated in controlled studies.
As with levodopa, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended therapy.
Patients with chronic wide-angle glaucoma may be treated cautiously with PARCOPA® provided the intraocular pressure is well controlled and the patient is monitored carefully for changes in intraocular pressure during therapy.
Dopaminergic agents, including levodopa, may be associated with somnolence and very
rarely episodes of sudden onset of sleep. In some cases, these episodes may occur without
awareness or warning during daily activities. Patients must be informed of this and
advised to exercise caution while driving or operating machines while being treated with
dopaminergic agents, including levodopa. Patients who have experienced somnolence
and/or an episode of sudden sleep onset must refrain from driving or operating machines
(see Information for Patients
Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2- to approximately 6-fold higher) of developing melanoma than the general population. Whether the increased risk observed was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear.
For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using PARCOPA® for any indication. Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists).
Phenylketonuric patients should be informed that PARCOPA® contains phenylalanine 3.4 mg per 25/100 orally disintegrating tablet, 3.4 mg per 10/100 orally disintegrating tablet, and 8.4 mg per 25/250 orally disintegrating tablet.
Patients should be instructed not to remove PARCOPA® Tablets from the bottle until just prior to dosing. With dry hands, the tablet should be gently removed and immediately placed on the tongue to dissolve and be swallowed with the saliva.
The patient should be informed that PARCOPA® is an immediate-release formulation of carbidopa and levodopa that is designed to begin release of ingredients within 30 minutes. It is important that PARCOPA® be taken at regular intervals according to the schedule outlined by the physician. The patient should be cautioned not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa and levodopa preparations, without first consulting the physician.
Patients should be advised that sometimes a “wearing-off” effect may occur at the end of the dosing interval. The physician should be notified if such response poses a problem to lifestyle.
Patients should be advised that occasionally, dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of PARCOPA®. Although the color appears to be clinically insignificant, garments may become discolored.
The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying, thus delaying the absorption of levodopa. Iron salts (such as in multi-vitamin tablets) may also reduce the amount of levodopa available to the body. The above factors may reduce the clinical effectiveness of the levodopa or carbidopa and levodopa therapy.
Patients should be alerted to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Patients should be advised to exercise caution
while driving or operating machinery and that if they have experienced somnolence
and/or sudden sleep onset, they must refrain from these activities. (See PRECAUTIONS: General
There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease, including PARCOPA®. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges or other urges while being treated with PARCOPA®. Patients should inform their physician if they experience new or increased gambling urges, increased sexual urges, or other intense urges while taking PARCOPA®. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking PARCOPA®.
Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, and bilirubin. Abnormalities in blood urea nitrogen and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during administration of carbidopa and levodopa than with levodopa.
Carbidopa and levodopa may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria.
Cases of falsely diagnosed pheochromocytoma in patients on carbidopa and levodopa therapy have been reported very rarely. Caution should be exercised when interpreting the plasma and urine levels of catecholamines and their metabolites in patients on levodopa or carbidopa and levodopa therapy.
Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with
PARCOPA® (carbidopa and levodopa orally disintegrating tablets).
Symptomatic postural hypotension has occurred when carbidopa and levodopa was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with PARCOPA® is started, dosage adjustment of the antihypertensive drug may be required.
For patients receiving MAO inhibitors (Type A or B), see CONTRAINDICATIONS
Concomitant therapy with selegiline and carbidopa and levodopa may be associated with
severe orthostatic hypotension not attributable to carbidopa and levodopa alone (see CONTRAINDICATIONS
There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and carbidopa and levodopa.
Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with PARCOPA® should be carefully observed for loss of therapeutic response.
Iron salts may reduce the bioavailability of levodopa and carbidopa. The clinical relevance is unclear.
Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties.
Carcinogenesis, mutagenesis, impairment of fertility
In a two-year bioassay of carbidopa and levodopa, no evidence of carcinogenicity was found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa.
In reproduction studies with carbidopa and levodopa, no effects on fertility were found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa.
Pregnancy Category C
No teratogenic effects were observed in a study in mice receiving up to 20 times the maximum recommended human dose of carbidopa and levodopa. There was a decrease in the number of live pups delivered by rats receiving approximately two times the maximum recommended human dose of carbidopa and approximately five times the maximum recommended human dose of levodopa during organogenesis. Carbidopa and levodopa caused both visceral and skeletal malformations in rabbits at all doses and ratios of carbidopa/levodopa tested, which ranged from 10 times/5 times the maximum recommended human dose of carbidopa/levodopa to 20 times/10 times the maximum recommended human dose of carbidopa/levodopa.
There are no adequate or well-controlled studies in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. Use of PARCOPA® in women of childbearing potential requires that the anticipated benefits of the drug be weighed against possible hazards to mother and child.
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when PARCOPA® is administered to a nursing woman.
Safety and effectiveness in pediatric patients have not been established. Use of the drug in patients below the age of 18 is not recommended.
The most common adverse reactions reported with carbidopa and levodopa therapy have
included dyskinesias, such as choreiform, dystonic, and other involuntary movements and

Management of acute overdosage with PARCOPA® is the same as management of acute
overdosage with levodopa. Pyridoxine is not effective in reversing the actions of
General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient
carefully observed for the development of arrhythmias; if required, appropriate anti-arrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as PARCOPA® should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known.
Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg.
DOSAGE AND ADMINISTRATION
Instructions for Use/Handling PARCOPA® Tablets
Just prior to administration, GENTLY remove the tablet from the bottle with dry hands. IMMEDIATELY place the PARCOPA® Tablet on top of the tongue where it will dissolve in seconds, then swallow with saliva. Administration with liquid is not necessary.
The optimum daily dosage of PARCOPA® must be determined by careful titration in each patient. PARCOPA® is available in a 1:4 ratio of carbidopa to levodopa (PARCOPA® 25/100) as well as 1:10 ratio (PARCOPA® 25/250 and PARCOPA® 10/100). Tablets of the two ratios may be given separately or combined as needed to provide the optimum dosage.
Studies show that peripheral dopa decarboxylase is saturated by carbidopa at approximately 70 to 100 mg a day. Patients receiving less than this amount of carbidopa are more likely to experience nausea and vomiting.
Usual Initial Dosage
Dosage is best initiated with one tablet of PARCOPA® 25/100 three times a day. This dosage schedule provides 75 mg of carbidopa per day. Dosage may be increased by one tablet every day or every other day, as necessary, until a dosage of eight tablets of PARCOPA® 25/100 a day is reached.
If PARCOPA® 10/100 is used, dosage may be initiated with one tablet three or four times a day. However, this will not provide an adequate amount of carbidopa for many patients. Dosage may be increased by one tablet every day or every other day until a total of eight tablets (2 tablets q.i.d.) is reached.
How to Transfer Patients from Levodopa
Levodopa must be discontinued at least twelve hours before starting PARCOPA®
(carbidopa and levodopa orally disintegrating tablets).
A daily dosage of
PARCOPA® should be chosen that will provide approximately 25 percent of the
previous levodopa dosage. Patients who are taking less than 1500 mg of levodopa a day should be started on one tablet of PARCOPA® 25/100 three or four times a day. The suggested starting dosage for most patients taking more than 1500 mg of levodopa is one tablet of PARCOPA® 25/250 three or four times a day.
Therapy should be individualized and adjusted according to the desired therapeutic response. At least 70 to 100 mg of carbidopa per day should be provided. When a greater proportion of carbidopa is required, one tablet of PARCOPA® 25/100 may be substituted for each tablet of PARCOPA® 10/100. When more levodopa is required, PARCOPA® 25/250 should be substituted for PARCOPA® 25/100 or PARCOPA® 10/100. If necessary, the dosage of PARCOPA® 25/250 may be increased by one-half or one tablet every day or every other day to a maximum of eight tablets a day. Experience with total daily dosages of carbidopa greater than 200 mg is limited.
Because both therapeutic and adverse responses occur more rapidly with PARCOPA® than with levodopa alone, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly with PARCOPA® than with levodopa. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients.
Addition of Other Antiparkinsonian Medications
Standard drugs for Parkinson’s disease, other than levodopa without a decarboxylase inhibitor, may be used concomitantly while PARCOPA® is being administered, although dosage adjustments may be required.
Interruption of Therapy
Sporadic cases of a symptom complex resembling Neuroleptic Malignant Syndrome
(NMS) have been associated with dose reductions and withdrawal of carbidopa and
levodopa. Patients should be observed carefully if abrupt reduction or discontinuation of
PARCOPA® is required, especially if the patient is receiving neuroleptics. (See WARNINGS.
If general anesthesia is required, PARCOPA® may be continued as long as the patient is permitted to take fluids and medication by mouth. If therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be administered as soon as the patient is able to take oral medication.
