The Clinical Efficacy Of Oral Levodopa Methyl-Ester Solution In Reversing Afternoon Off Periods In Parkinsons-Disease

We compared the efficacy of a single dose of an oral solution of levodopa methyl ester (ME) to that of standard levodopa, in the form of a single dose of Madopar, in reversing afternoon "off" periods in 12 patients with Parkinson's disease (PD). The highly soluble ME solution led to a significantly more rapid reversal of "off" periods. This preparation may therefore convey a clinical advantage in patients experiencing motor fluctuations whilst taking multiple daily dosages of levodopa, particularly in those with long or highly variable latency to the next "on" period.
