Biological Activity
| Description | Piribedil (Trivastal, Trivastan) is a relatively selective dopamine (D2/D3) agonist with moderate antidepressant activity. It also has α2-adrenergic (α2A/α2C) antagonist properties. | ||||||||

||||||||
| In vitro | Piribedil is a direct dopamine receptor agonist used for the treatment of Parkinson's disease and of other clinical disorders involving dysfunction of the dopaminergic system. Piribedil has 20 times higher affinity for dopamine D3 than for dopamine D2-like receptors, and very low affinity for the dopamine D1 receptor subtype in rat brain. Piribedil is a potent inhibitor at dopamine D3 receptors with affinity between 30 and 60 nM[1]. Although piribedil is not a potent agent, its affinity at hα2A- and hα2C-ARs was comparable to that at D2 receptors[3]. | ||||||||
| In vivo | Piribedil (2.5-4.0 mg/kg s.c.) accelerates hippocampal NE synthesis, elevates dialysis levels of NE in hippocampus and frontal cortex, and blocks hypnotic-sedative properties of the α2-AR agonist xylazine[3]. Although a subchronic treatment with piribedil (0.1-2 mg/kg) is not effective, a dose of 0.3 mg/kg administered for 3 weeks significantly reverses the akinetic deficits produced by the striatal dopamine depletion and progressively improves attentional deficits. When coadministered with the dopamine prodrug L-DOPA (3 mg/kg), piribedil (0.3 mg/kg) promotes a rapid and full recovery of preoperative performance[2]. |
