Summary
Psilocybin shows promise for depression, a compelling finding in the burgeoning field of Psychedelics and Drug Studies. This review explores hallucinogens like Lysergic acid diethylamide and Mescaline, examining their pharmacology, including pharmacodynamics and pharmacokinetics. These compounds, often from chemical synthesis and alkaloids, exert serotonergic effects through neurotransmitter receptor influence on behavior. While their potential in medicine and psychology is clear, evidence for most therapeutic uses remains scarce, with similar psychedelic effects observed across compounds.
Abstract
Psychedelic compounds, including psilocybin, LSD (lysergic acid diethylamide), DMT (N,N -dimethyltryptamine), and 5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine), all of which are serotonin 2A receptor agonists, are being investigated as potential treatments. This review aims to summarize the current clinical research on these 4 compounds and mescaline to guide future research. Their mechanism(s) of action, pharmacokinetics, pharmacodynamics, efficacy, and safety were reviewed. While evidence for therapeutic indications, with the exception of psilocybin for depression, is still relatively scarce, we noted no differences in psychedelic effects beyond effect duration. Therefore, it remains unclear whether different receptor profiles contribute to the therapeutic potential of these compounds. More research is needed to differentiate these compounds in order to inform which compounds might be best for different therapeutic uses.
