<unk>  (brand name in Germany Dopergin) is an anti-Parkinson's drug of the iso-ergoline class, chemically related to the dopaminergic ergoline Parkinson's drugs.<unk>  is described as free base (see table on the right) and as hydrogenmaleate salt.<unk>  is used to lower prolactin and, in low doses, to prevent migraine attacks. The use of<unk>  as initial anti-Parkinsonian treatment has been advocated, delaying the need for levodopa until<unk>  becomes insufficient for controlling the Parkinsonian disability. Preliminary trials suggest that the dermal application of<unk>  may be useful in the treatment of Parkinson's disease.<unk>  is not currently available in the US.<unk>  (Dopergin, Proclacam, Revanil) is an antiparkinson agent of the iso-ergoline class, chemically related to the dopaminergic ergoline Parkinson's drugs.<unk>  is described as free base (see table on the right) and as hydrogen maleate salt.<unk>  is used to lower prolactin and, in low doses, to prevent migraine attacks.

Preliminary trials suggest that the dermal application of<unk>  may be useful in the treatment of Parkinson's disease. As<unk>  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.<unk>  is not currently available in the US, as the drug was not a commercial success in comparison with other dopamine receptor agonist anti-parkinsonian compounds. It is still used clinically in a number of countries in the EU and is still commercially available in the UK and China.
A Study has failed to find any association between<unk>  and fibrotic cardiac valvulopathy.
