Pergolide mesylate binds to and activates dopamine receptor subtypes D1 and D2, resulting in prolactin secretion inhibition, transient increase in serum concentration of growth hormone, and decrease in serum concentration of luteinizing hormone. Direct stimulation of postsynaptic dopamine receptors in the nigrostriatal system, may account for this agent's antiparkinson activity."}]
