Sample Use Guides

For the treatment of Parkinson's disease as a monotherapy, piribedil should be administered orally at 150 to 250 mg.
Route of Administration: Oral
Binding of piribedil to D2, D3 and D4 receptors was measured using [3H]spiperone as a radiolabel. Coronal sections from rat brains were cut at the level of the anterior caudate-putame. The sections were thaw-mounted on gelatin-coated glass slides. Sections were incubated for 5 min in a 50mM Tris-HCl buffer, then were incubated for 30 min at room temperature in the incubation buffer. Piribedil was tested in vitro at 5 different concentrations, from 10 uM to 1 nM.
