Flashback phenomena after administration of LSD and psilocybin in controlled studies with healthy participants

Psychopharmacology January 25, 2022 Felix Müller, Elias Kraus, Friederike Holze et al. 64 citations

Abstract Background LSD and psilocybin are increasingly used in phase I trials and evaluated as therapeutic agents for mental disorders. The phenomenon of reoccurring drug-like experiences after the acute substance effects have worn off was described for both substances and especially attributed to LSD. According to the DSM-V, the persisting and distressing manifestation of these experiences is...

Prediction of MDMA response in healthy humans: a pooled analysis of placebo-controlled studies

Journal of Psychopharmacology March 30, 2021 Erich Studerus, Patrick Vizeli, Samuel Harder et al. 51 citations

Background: 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”) is used both recreationally and therapeutically. Little is known about the factors influencing inter- and intra-individual differences in the acute response to MDMA. Effects of other psychoactive substances have been shown to be critically influenced by personality traits and mood state before intake. Methods: We pooled data from...

MDMA-induced changes in within-network connectivity contradict the specificity of these alterations for the effects of serotonergic hallucinogens

Neuropsychopharmacology November 20, 2020 Felix Müller, Friederike Holze, Patrick C. Dolder et al. 43 citations

Abstract It has been reported that serotonergic hallucinogens like lysergic acid diethylamide (LSD) induce decreases in functional connectivity within various resting-state networks. These alterations were seen as reflecting specific neuronal effects of hallucinogens and it was speculated that these shifts in connectivity underlie the characteristic subjective drug effects. In this study, we...

Acute dose-dependent effects of lysergic acid diethylamide in a double-blind placebo-controlled study in healthy subjects

Neuropsychopharmacology October 15, 2020 Friederike Holze, Patrick Vizeli, Laura Ley et al. 243 citations

Abstract Growing interest has been seen in using lysergic acid diethylamide (LSD) in psychiatric research and therapy. However, no modern studies have evaluated subjective and autonomic effects of different and pharmaceutically well-defined doses of LSD. We used a double-blind, randomized, placebo-controlled, crossover design in 16 healthy subjects (eight women, eight men) who underwent six 25...

Distinct acute effects of LSD, MDMA, and d-amphetamine in healthy subjects

Neuropsychopharmacology November 16, 2019 Friederike Holze, Patrick Vizeli, Felix Müller et al. 250 citations

Abstract Lysergic acid diethylamide (LSD) is a classic psychedelic, 3,4-methylenedioxymethamphetamine (MDMA) is an empathogen, and d -amphetamine is a classic stimulant. All three substances are used recreationally. LSD and MDMA are being investigated as medications to assist psychotherapy, and d -amphetamine is used for the treatment of attention-deficit/hyperactivity disorder. All three...
