[Benefit of L-DOPA-without-DCI (decarboxylase inhibitor) therapy on wearing-off phenomenon in advanced stages of Parkinson's disease patients].

Abstract

Motor fluctuation is the most annoying complication experienced by patients in the advanced stages of Parkinson's disease. A Combination therapy of a dopamine receptor agonist and levodopa/DCI(DOPA-decarboxylase inhibitor) is commonly used to control the complication. Although administration of levodopa/DCI is useful in minimizing peripheral side effects of levodopa, it increases the incidence of motor complications due to the marked fluctuation of plasma levodopa level. The use of levodopa without DCI might be an option for controlling motor fluctuation, because the extent of plasma levodopa level fluctuation is smaller when levodopa is administered without DCI than with DCI. Six patients with Parkinson's disease who had troublesome motor complications under levodopa/DCI and DA agonist combination therapy were compared in terms of the extent of motor complications and their satisfaction after changing their therapy from levodopa/DCI to levodopa without DCI. The change from levodopa/DCI to levodopa(without DCI) was carried out all at once, and the levodopa/DCI to levodopa dose ratio was started at 1:4. The dose of levodopa(without DCI) was then increased gradually until motor complications improved or side effects were observed in patients. Except two patients who voluntarily quitted levodopa and restarted DOPA/DCI before the dose of levodopa fixed, all cases showed improvement of wearing-off phenomenon. No adverse event was observed. Levodopa-without-DCI-therapy was effective for controlling motor fluctuation in patients of Parkinson's disease in advanced stages.
