Elinogrel (INN,[2] USAN) was an experimental antiplatelet drug acting as a P2Y12 inhibitor. Similarly to ticagrelor and in contrast to clopidogrel, elinogrel was a reversible inhibitor that acted fast and short (for about 12 hours), and it was not a prodrug but pharmacologically active itself. The substance was used in form of its potassium salt, intravenously for acute treatment and orally for long-term treatment.[3] Development was terminated in 2012.

History

The substance was originally developed by Portola Pharmaceuticals, with Phase II clinical trials conducted around 2008–2011.[4] In February 2009, Novartis bought worldwide rights to develop it further, intending to conduct Phase III studies and commercialise the drug.[5] The development of the drug was terminated in January 2012 by Novartis.[6]
