Psilocybin shows promising results in subjects continuing to use an antidepressant

The Brown University Psychopharmacology Update October 4, 2023

Ongoing antidepressant treatment is believed to alter the psychedelic effect of psilocybin, so most psilocybin trials have required withdrawal from antidepressants before enrollment. There has been recent evidence, however, that administration of a selective serotonin reuptake inhibitor (SSRI) does not significantly alter the acute subjective effects of psilocybin. A Phase 2 open-label trial...

LSD reduces anxiety symptoms in Phase 2 trial

The Brown University Psychopharmacology Update 2023

The effort to identify alternative treatments for anxiety has led to research into the potential of lysergic acid diethylamide (LSD) in reducing anxiety symptoms. Based on results of a placebo‐controlled pilot study showing that two high doses of LSD in patients with a life‐threatening illness resulted in reductions in anxiety for up to 2 months, investigators conducted a Phase 2 study to...

High dose of psilocybin effective for treatment‐resistant depression

The Brown University Psychopharmacology Update December 27, 2022

Adults with treatment‐resistant depression who received a single 25‐mg dose of psilocybin saw significant improvement in depressive symptoms relative to a control dose at 3 weeks, a Phase 2b trial has found. A smaller 10‐mg dose of psilocybin did not result in significant improvement over the control dose of 1 mg, and adverse events were common in both of the higher‐dose groups. Study results...

History of epilepsy increases risk of psychedelic‐induced seizures

The Brown University Psychopharmacology Update December 10, 2022

Classic psychedelic drugs such as psilocybin have been associated with reduced depressive symptoms when used as an adjunct to therapy, but concern remains over the potential for adverse events such as seizures when these drugs are used outside controlled clinical settings. A study used a survey of U.S. adults to examine the association between use of classic psychedelics and seizures. The...
