Moreover, the role of 5-HT2A receptors, involved in the psychedelic experience, on the therapeutic efficacy of psilocybin is still poorly understood. For example, pre-administration of trazodone, a 5-HT2A antagonist antidepressant, could annihilate the acute subjective effects of psilocybin without altering its beneficial effects (Rosenblat et al., 2023). We intend to test this hypothesis by comparing, in a randomized, double-blind, placebo-controlled study, the effect of two possible doses of trazodone (total or partial occupancy of 5-HT2A receptors) on the benefit\u002Frisk ratio of psilocybin.\n\nWe hypothesize that the therapeutic effects of psilocybin are partially independent of 5-HT2A receptor activation and thus persist even after total or partial neutralization of its acute subjective effects.",[103,104],"Depression - Major Depressive Disorder","Treatment-resistant Depression (TRD)",[106,107,108,109],"psilocybin","trazodone","TRD","RCT","NOT_YET_RECRUITING","2025-09-29",{"date":113,"type":114},"2025-10-07","ACTUAL",{"date":116,"type":97},"2025-10-08",{"date":118,"type":97},"2030-06-30",{"name":5,"class":6},1]
