MedKoo CAT#: 522378

CAS#: 733717-87-8

Description: SCH-50911 is a selective GABAB antagonist developed by Schering-Plough Corporation. Its main applications are in pharmacology research. SCH-50911 also acts as an anticonvulsant under normal conditions, and so counteracts both the depressant and pro-convulsant effects of GHB overdose. This pharmacological profile makes SCH-50911 a promising candidate as a GHB antidote for human use, and might also make it useful for treating overdoses of other GABAB agonists such as Baclofen.

Additional Information

SCH-50911 is likely to be a useful antidote for GHB overdose in non-addicted individuals, its use in people who are dependent on GHB or its analogues could be potentially dangerous as it might precipitate acute withdrawal symptoms, and additional anticonvulsants such as diazepam would most likely be required to counteract the risk of life-threatening seizures.
