Serotonergic hallucinogens in the treatment of anxiety and depression in patients suffering from a life-threatening disease: A systematic review

Abstract

Anxiety and depression are some of the most common psychiatric symptoms of patients suffering with life-threatening diseases, often associated with a low quality of life and a poor overall prognosis. 5-HT2A-receptor agonists (serotonergic hallucinogens, ‘psychedelics’) like lysergic acid diethylamide (LSD) and psilocybin were first investigated as therapeutic agents in the 1960s. Recently, after a long hiatus period of regulatory obstacles, interest in the clinical use of these substances has resumed. The current article provides a systematic review of studies investigating psychedelics in the treatment of symptoms of existential distress in life-threatening diseases across different periods of research, highlighting how underlying concepts have developed over time. A systematic search for clinical trials from 1960 to 2017 revealed 11 eligible clinical trials involving a total number of N=445 participants, of which 7 trials investigated the use of lysergic acid diethylamide (LSD) (N=323), 3 trials investigated the use of psilocybin (N=92), and one trial investigated the use of dipropyltryptamine (DPT) (N=30). The 4 more recent randomized controlled trials (RCTs) (N=104) showed a significantly higher methodological quality than studies carried out in the 1960s and 1970s. Evidence supports that patients with life threatening diseases associated with symptoms of depression and anxiety benefit from the anxiolytic and antidepressant properties of serotonergic hallucinogens. Some studies anecdotally reported improvements in patients´ quality of life and reduced fear of death. Moreover, low rates of side effects were reported in studies that adhered to safety guidelines. Further studies are needed to determine how these results can be transferred into clinical practice.

Psychotherapy with Adjuvant use of Serotonergic Psychoactive Substances: Possibilities and Challenges

Abstract

Background Recently, scientific interest in the therapeutic potential of serotonergic and psilocybin hallucinogens (psychedelics) such as lysergic acid diethylamide (LSD) and entactogens like 3,4-methylendioxymethamphetamine (MDMA) within the framework of psychotherapy has resumed. The present article provides an overview on the current evidence on substance-assisted psychotherapy with these substances.
Method A selective search was carried out in the PubMed and Cochrane Library including studies investigating the clinical use of serotonergic psychoactive substances since 2000.
Results Studies were found investigating the following indications: alcohol (LSD and psilocybin) and tobacco addiction (psilocybin), anxiety and depression in patients suffering from life-threatening somatic illness (LSD and psilocybin), obsessive-compulsive disorder (OCD) (psilocybin), treatment-resistant major depression (psilocybin), and posttraumatic stress disorder (PTSD) (MDMA).
Discussion Substance use disorders, PTSD and anxiety and depression in patients suffering from life-threatening somatic illness belong to the indications with the best evidence for substance-assisted psychotherapy with serotonergic psychoactive agents. To date, studies indicate efficacy and relatively good tolerability. Further studies are needed to determine whether these substances may represent suitable and effective treatment options for some treatment-resistant psychiatric disorders in the future.

Peak experiences and the afterglow phenomenon: When and how do therapeutic effects of hallucinogens depend on psychedelic experiences?

Abstract

Interest in the therapeutic potential of psychedelic substances has recently resumed. During an early phase of human psychedelic research, their therapeutic application in different pathologies had been suggested, and the first evidence for efficacy was provided. The range of recent clinical applications of psychedelics spans from cluster headaches and obsessive-compulsive disorder to addiction and the treatment of fear and anxiety in patients suffering from terminal illness, indicating potentially different therapeutic mechanisms. A variety of approaches in psychotherapy emphasize subjective experiences, such as so-called peak experiences or afterglow phenomena, as differentially mediating therapeutic action. This review aims to re-evaluate earlier and recent concepts of how psychedelic substances may exert beneficial effects. After a short outline of neurophenomenological aspects, we discuss different approaches to how psychedelics are used in psychotherapy. Finally, we summarize evidence for the relationship between subjective experiences and therapeutic success. While the distinction between pharmacological and psychological action obviously cannot be clear-cut, they do appear to contribute differently from each other when their effects are compared with regard to pathologies.
