Oral administration of (S)-ketamine for treatment-resistant depression (TRD), as alternative to the registered intranasal or off-label intravenous administrations, has high potential. However, it is characterized by an extensive first-pass metabolism, resulting in low (S)-ketamine exposure and high levels of active metabolites, including (S)-norketamine and (S)-hydroxynorketamine. The relative...
N,N-Dimethyltryptamine (DMT) is currently being studied for its therapeutic potential in various psychiatric disorders. An understanding of its pharmacokinetics (PK) is essential to determine appropriate dose ranges in future clinical studies. We conducted a systematic literature review on the PK of DMT. Clinical studies that administered known amounts of DMT and reported PK data and/or...

Cannabinoid receptor type 1 (CB1 ) antagonists have been developed for the treatment of obesity and associated risk factors. Surinabant is a high affinity CB1 antagonist in vitro. The aim of this study was to assess the magnitude of inhibition by surinabant of CNS effects and heart rate induced by Δ(9) -tetrahydrocannabinol (THC) in humans. This was a double-blind, placebo-controlled,...
