Lisuride is an antiparkinson agent of the iso-ergoline class, chemically related to the dopaminergic ergoline Parkinson's drugs. Lisuride is described as free base and as hydrogen maleate salt. Lisuride is used to lower prolactin and, in low doses, to prevent migraine attacks. The use of lisuride as initial anti-Parkinsonian treatment has been advocated, delaying the need for levodopa until lisuride becomes insufficient for controlling the Parkinsonian disability. Preliminary trials suggest that the dermal application of lisuride may be useful in the treatment of Parkinson's disease. As lisuride is very poorly absorbed when take orally and has a short half-life, continuous transdermal administration offers significant advantages and could make the compound a far more consistent therapeutic.Lisuride is a dopamine and a partial agonist for several serotonin receptors. It is an antagonist at the serotonin 5-HT2B receptor.
