Arbaclofen placarbil (/ɑːrˈbæklfɛn pləˈkɑːrbɪl/ ar-BAK-loh-fen plə-KAR-bil, also known as XP19986) is a prodrug of R-baclofen. Arbaclofen placarbil possesses more favorable pharmacokinetic profile than baclofen, with less fluctuations in plasma drug levels. It was being developed as a potential treatment for patients with GERD and spasticity due to multiple sclerosis; however, in May 2013 XenoPort announced the termination of development because of unsuccessful results in phase III clinical trials.[1]

It is being developed as an addiction medicine to treat alcoholism. [2]
