Talnetant

Talnetant (SB-223,412) is a neurokinin 3 receptor antagonist developed by GlaxoSmithKline, which is being researched for several functions (primarily treatment of irritable bowel syndrome, despite a 2007 study finding no statistically significant improvement in rectal hypersensitivity over placebo). Its use as a potential antipsychotic drug for the treatment of schizophrenia has also been discontinued.[1][2][3][4]
