Twice As Many Parkinson's Disease Patients Prefer Orally Dissolving Form of Carbidopa-Levodopa to Conventional Tablets

A clinical study published in the January 2005 issue of "Clinical Therapeutics" showed that more than twice as many Parkinson's disease patients prefer Parcopa(TM) (carbidopa-levodopa orally disintegrating tablets) to conventional carbidopa-levodopa tablets.

The primary factors influencing their preference were greater access to medication to treat "off" times, ease of performing daily activities, use for nighttime dosing and feeling less self-conscious about others noticing medication use.

Parcopa is a unique formulation of carbidopa-levodopa that dissolves on the tongue without the need for water.

"Since Parkinson's disease patients experience symptoms such as tremors, rigidity and episodes of decreased movement or complete immobility, especially in the morning, compliance and access to medication can be a problem," said Michele Tagliati, MD, Director of the Parkinson's Disease Center at the Mount Sinai Medical Center in New York.

"This study showed that Parcopa offers important benefits for many patients. Those who expressed a preference, preferred an orally dissolving tablet because they felt it was more convenient and easier to access -- which is particularly important for patients suffering from parkinsonian symptoms."

The multicenter, open-label, sequential study compared preferences for carbidopa-levodopa orally disintegrating tablets versus conventional tablets in 60 Parkinson's disease patients who had taken a stable dose of conventional carbidopa-levodopa for at least 30 days prior to the trial.

Patients received conventional tablets for 7 +/- 3 days, followed by Parcopa for 14 +/- 3 days.

During the last 3 days of each treatment period, they recorded their "on" and "off" times and medication use in a diary. On the last day of each treatment period, the Unified Parkinson's Disease Rating Scale (UPDRS) was administered. At the end of the study, patients completed a Global Preference Questionnaire (GPQ).

 Nearly half (45%) of the study subjects preferred orally dissolving tablets, 35% had no preference and 20% preferred the conventional tablets. Factors cited as contributing to their preference for the orally dissolving formulation included:

Reasons Cited for Preference Percentage of Patients

  • Greater access to medication to treat "off" times 50%
  • Easier to perform daily activities 47%
  • Reduced concern about swallowing medication 45%
  • Use for nighttime dosing 42%
  • Less self-conscious about use in public 42%

Recently approved by the FDA, Parcopa (carbidopa-levodopa orally disintegrating tablets) is a combination of carbidopa and levodopa in tablets that dissolve rapidly on the tongue, without the need for water.

Parcopa's orally dissolving formulation is designed to provide Parkinson's disease patients with improved access to their medication. Parcopa is used to treat symptoms of Parkinson's disease, including tremors, stiffness and slowness of movement, and may permit the patient better mobility.

Parcopa is available in the same strengths and has the same dosage schedule as conventional Sinemet(R) (carbidopa-levodopa) tablets.

The most common side effects include involuntary movements and nausea. Each 10 mg/100 mg tablet and each 25 mg/100 mg tablet contain phenylalanine 3.4 mg. Each 25 mg/250 mg tablet contains phenylalanine 8.4 mg. For more information about Parcopa, talk to your healthcare provider or visit
