Description

Packaging

10, 50 mg in glass bottle

Application

Pramipexole dihydrochloride has been used as a D2-like DR (dopaminergic receptor) agonist in study associated with Parkinson’s disease. It has also been used as a D2/D3 receptor agonist to study risky decision-making in rats.

Biochem/physiol Actions

Pramipexole is a dopamine agonist active at D3 and D2 receptor subtypes. Pramipexole has been found to have neuroprotective effects independent of its dopamine receptor agonism. It reduces mitochondrial reactive oxygen species (ROS) production and inhibits the activation of apoptotic pathways.

Pramipexole is a therapeutic agent for Parkinson’s disease and restless leg syndrome. It also exhibits antidepressant responses in patients suffering from MDD (major depressive disorder) and bipolar depression.

General description

Pramipexole belongs to non-ergoline class and is derived from benzothiazole. It has strong affinity for D2 and D3 receptors (dopamine receptors) compared to other ergoline-derived drugs. However, it does not associate with non-dopamine receptors, for instance adrenergic and serotonin receptors.
