SR-142,948 is a drug used in scientific research which is a non-peptide antagonist selective for the neurotensin receptors, although not selective between subtypes.[1] It has been used to study the role of neurotensin in the regulation of dopamine receptor activity[2][3][4][5] and glutamate signalling in the brain,[6][7] and in animal studies SR-142,948 blocked the effects of stimulant drugs,[8] including MDMA.[9]
