Effects of serotonin 2A/1A receptor stimulation by psilocybin on alcohol addicted patients: a randomized double-blind placebo-controlled study
Two billion people globally consume alcohol, leading in 2016 to 2.8 million deaths (5.2% of all deaths) and 99.2 million Disability Adjusted Life Years (DALYs) lost (4.2% of all DALYs). Of all the diseases, conditions, and injuries attributable to alcohol use, alcohol use disorders (AUDs) create the largest health burden globally. However, approved pharmacological treatments for alcoholism are limited in their effectiveness. A recent proof of- concept study testing psilocybin in ten alcohol dependent patients provides encouraging efficacy results and safety data. The investigators, therefore, propose to test the efficacy of psilocybin for treating alcohol use disorder and study its underlying neurobiological mechanisms in a randomized, placebo controlled, double blind study. To evaluate effects of psilocybin on alcohol use behaviour, clinical symptoms, neurocognitive and emotional measures in patients with alcohol use disorder.
The present clinical trial aims at investigation the clinical and mechanistic effects of Psilocybin in Alcohol Addicted Patients.
Patients with alcohol use disorder who have undergone withdrawal treatment within the last 6 weeks will be investigated in a single-centre, double-blind, placebo-controlled, parallel-group design clinical trial contrasting the acute and persisting effects of psilocybin to those of placebo. Patients will be randomly assigned to psilocybin or placebo group with a 1:1 allocation ratio. The study comprises a total of 6 visits during 6 weeks and two follow-up online surveys (3 and 6 months after treatment). In addition, two follow-up surveys that can be completed from home will guarantee monitoring of long-lasting changes in symptomology and ensure all potential side-effects can be captured. On the treatment visit, a single dose of psilocybin (25mg) or placebo will be administered. Patients will be monitored until all effects have worn off.

The major of two hallucinogenic components of Teonanacatl, the sacred mushroom of Mexico, the other component being psilocin. (From Merck Index, 11th ed)
An acute organic mental disorder induced by cessation or reduction in chronic alcohol consumption. Clinical characteristics include CONFUSION; DELUSIONS; vivid HALLUCINATIONS; TREMOR; agitation; insomnia; and signs of autonomic hyperactivity (e.g., elevated blood pressure and heart rate, dilated pupils, and diaphoresis). This condition may occasionally be fatal. It was formerly called delirium tremens. (From Adams et al., Principles of Neurology, 6th ed, p1175)
Substances interfering with the metabolism of ethyl alcohol, causing unpleasant side effects thought to discourage the drinking of alcoholic beverages. Alcohol deterrents are used in the treatment of alcoholism.
