Objectives And Methods:
This study investigated the ease with which 52 Parkinson's disease patients already receiving adjunct entacapone to traditional levodopa were switched to Stalevo (levodopa/carbidopa/entacapone).
Results:
The switch to Stalevo was straightforward for most patients taking standard-release levodopa with 86% of these patients being able to replace their entire regimen without having to change the amount of levodopa taken. The majority of patients (54%, P = 0.162) preferred Stalevo; 31% preferred their prior treatment regimen; 15% had no preference. Patients found Stalevo more simple to dose (94%), more convenient to use (84%), easier to handle (84%), easier to remember (67%) and easier to swallow (59%), compared with their previous medication.
Conclusions:
Stalevo was well tolerated, with a low incidence of adverse events. The study shows that Stalevo is an effective, preferred and well-tolerated means of delivering levodopa/carbidopa/entacapone in one easy-to-use tablet.
