title: Duodenal levodopa infusion in Parkinson's disease--long-term experience.
abstract: Motor fluctuations in parkinsonian patients can be reduced by intraduodenal infusion of levodopa. Between 1991 and 1998 continuous daytime administration of levodopa through a transabdominal port has been used in 28 very advanced patients over a total period of 1045 months. A stable suspension of levodopa and carbidopa (Duodopa) has been developed. Patients were characterized by early onset, long history of disease and levodopa therapy. The reason for infusion was in all cases related to on-off fluctuations. All patients experienced a general improvement after the introduction of continuous treatment. There have been no severe complications. Six patients have taken the decision to curtail their treatment. The mean daily levodopa consumption has been slightly reduced on infusion as compared to oral therapy. Nine of the first group of patients participating in the new therapy have been regularly evaluated by means of rating scales and movement analyses. Short-term results have already been published and a follow-up showing continued positive effect after 4-7 years of continuous duodenal infusion is presented.
