Dopamine agonists are an important component of Parkinson's therapy. When weighing up the various therapy options, therapy with levodopa has recently been increasingly preferred due to its stronger efficacy and the ostensibly lower rate of side effects. The advantage of the lower incidence of motor complications during therapy with dopamine agonist...

Compounds, which inhibit enzyme activity of catechol-O-methyltransferease, are commonly employed in combination with levodopa/dopadecarboxylase inhibitor formulations in patients with Parkinson’s disease. They ameliorate wearing-off symptoms by prolongation of the peripheral half-life of levodopa, increase of the peripheral levodopa bioavailability...
Chapter
Antiparkinsonian activity of amantadine was first described in 1969 and was confirmed by several trials in later years. The improvement of parkinsonian symptoms is mild. However, in patients with motor fluctuations, clear reduction of dyskinesia could be observed. A possible neuroprotective impact is still under discussion, but lacking evidence. Th...
