Rada Medwave, 2017, 17, 7, e7010 DOI: 10.5867/medwave.2017.07.7010 Abstract Cannabidiol has recently been proposed as an antipsychotic for schizophrenia. However, its clinical use and safety is controversial. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified six systematic reviews incorporating four primary studies overall, including two randomized trials. We extracted data from the systematic reviews, reanalyzed data from primary studies, conducted a meta-analysis and generated a summary of findings table [...]

Koethe, C. Rohleder CNS Drugs, 2018 Jul;32(7):605-619. doi: 10.1007/s40263-018-0539-z. Abstract The term schizophrenia describes a group of multifaceted psychiatric conditions causing significant impairment of the quality of life of affected patients. Although multiple pharmacological treatment options exist, e.g. first- or second-generation antipsychotics, these therapeutics often cause disturbing side effects, such as extrapyramidal symptoms, prolactin increase, sexual dysfunction and/or metabolic syndrome. Furthermore, cognitive impairments and negative symptoms, two factors significantly influencing the course and outcome, are not sufficiently addressed by the available [...]

What is less well known by the public is that MDMA started its life as a therapeutic agent and that in recent years an increasing amount of clinical research has been undertaken to revisit the drug’s medical potential. MDMA has unique pharmacological properties that translate well to its proposed agent to assist trauma-focused psychotherapy. Psychological trauma—especially that which arises early in life from child abuse—underpins many [...]
