DOI: 10.1016/j.jad.2017.07.042
Abstract: BACKGROUND NK1 receptor antagonists were abandoned despite antidepressant efficacy in five randomized clinical trials. The loss of confidence may be attributed to the failure of a Phase III clinical program with the NK1 receptor antagonist… read more here.

DOI: 10.1038/s41398-025-03582-2
Abstract: Approximately 20–30% of patients treated for schizophrenia concomitantly take two or more antipsychotic substances, despite the limited evidence that antipsychotic combination treatment is superior to monotherapy. Positron emission tomography (PET) studies can reveal the relationship… read more here.
