In de novo patients with early parkinsonism, acute subcutaneous challenges with apomorphine monotherapy have been proposed to test the dopaminergic responsiveness of the motor symptoms in order to help clinicians in differential diagnosis between "idiopathic" Parkinson's disease and other parkinsoni

โฆ Synopsis
Piribedil is a non-ergot derivative D2/D-3 agonist 1 with alpha-2 antagonistic effects 2 . Piribedil is effective in reversing parkinsonian symptoms in the MPTP-treated primate 3 . The clinical effects of piribedil cause lower prolactin plasma levels and blood pressure, and induces nausea. There is also some evidence that piribedil has neuroprotective effects in experimental models 4 .
PHARMACOKINETICS
Piribedil is administered orally, Tmax is reached within 1 hour, and it has a relatively long plasma elimination half-life (20 hours). Piribedil solubility allows it to be used intravenously for experimental purposes or acute challenge tests.

Lisuride is an alpha-amino-ergoline with D2 receptor agonist properties and has no apparent D1 receptor effects. Similar to most ergotamine derivatives, lisuride also has 5-HT2 activity. In animal models of Parkinson's disease (PD), lisuride antagonizes reserpine-induced akinesia and induces rotatio
