It acts as a selective antagonist of the κ-opioid receptor.^[2]^[3] The drug is also more weakly an antagonist of the μ-opioid receptor, with about 31-fold lower affinity and 27-fold lower inhibitory potency at the μ-opioid receptor relative to the κ-opioid receptor.^[3]

It was originated by Pfizer and is under development by Cerevel Therapeutics.^[2] As of September 2022, icalcaprant is in phase 1 clinical trials for major depressive disorder and is in the preclincal stage of development for substance-related disorders.^[2]
