Ketanserin blocks the subjective effects of psychedelics
Ketanserin has been repeatedly shown to attenuate or abolish the subjective experience of psychedelics (Becker2023, Preller2017, Burt2018, Vollenweider1998, Kometer2012, Madsen2019, Preller2019), though on a pharmacological level, the interactions appear to be more complex, particularly regarding the antidepressant effects of Psychedelics (see: Moliner2023).
