Talipexole (B-HT920, Domnin) is a dopamine agonist that is marketed as a treatment for Parkinson's Disease in Japan by Boehringer Ingelheim; it was introduced in 1996.^[1] As of December 2014 it was not approved for marketing in the US nor in Europe.^[2]

Talipexole is a D₂ dopamine receptor agonist and interacts both pre- and post-synaptic receptors. It also is an α2-adrenergic agonist.^[3]

The main side effects are drowsiness, dizziness, hallucinations and minor gastrointestinal complaints.^[3] In 2008 the Japanese Ministry of Health, Labour, and Welfare mandated that Boehringer add a warning to the label concerning the risk of sudden onset of sleep.^[4]^: 15
