NK3 receptor antagonists

Fezolinetant, sold under the brand name Veozah, among others, is a medication used for the treatment of hot flashes (vasomotor symptoms) due to menopause. It is a small-molecule, selective neurokinin-3 (NK3) receptor antagonist taken by mouth. It was developed by Astellas Pharma, which acquired it from Ogeda (formerly Euroscreen) in April 2017.

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.
