Present and future of metabolic and metabolomics studies focused on classical psychedelics in humans.

Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie December 31, 2023 Francisco Madrid-Gambin, David Fabregat-Safont, Alex Gomez-Gomez et al. 12 citations

Psychedelics are classical hallucinogen drugs that induce a marked altered state of consciousness. In recent years, there has been renewed attention to the possible use of classical psychedelics for the treatment of certain mental health disorders. However, further investigation to better understand their biological effects in humans, their mechanism of action, and their metabolism in humans is...

A Comparison of Acute Pharmacological Effects of Methylone and MDMA Administration in Humans and Oral Fluid Concentrations as Biomarkers of Exposure

Biology August 17, 2021 Lourdes Poyatos, Esther Papaseit, Eulàlia Olesti et al. 26 citations

Considered the β-keto analogue of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy), 3,4-Methylenedioxymethcathinone (methylone) is a synthetic cathinone. Over the years, methylone has been used as a substitute for conventional psychostimulants, such as MDMA. To date, little is known about the human pharmacology of methylone; the only available information has been provided by surveys or...

Acute Pharmacological Effects of Oral and Intranasal Mephedrone: An Observational Study in Humans

Pharmaceuticals January 28, 2021 Esther Papaseit, Eulàlia Olesti, Clara Pérez‐mañá et al. 30 citations

Mephedrone (4-methylmethcathinone) is a synthetic cathinone with psychostimulant properties which remains one of the most popular new psychoactive substances (NPS). It is frequently used orally and/or intranasally. To date, no studies have evaluated the acute effects and pharmacokinetics after self-administration of mephedrone orally (ingestion) and intranasally (insufflation) in naturalistic...

Acute Effects of 2C-E in Humans: An Observational Study

Frontiers in Pharmacology March 18, 2020 Esther Papaseit, Marta Torrens, Mireia Ventura et al. 20 citations

2,5-Dimethoxy-4-ethylphenethylamine (2C-E) is psychedelic phenylethylamine, with a chemical structure similar to mescaline, used as new psychoactive substance (NPS). It inhibits norepinephrine and serotonin uptake and, more relevant, acts as a partial agonist of the serotonin 2A (5-HT2 A), 2B (5-HT2 B), and (5-HT2 C) receptors. Consumers have reported that 2C-E induces mild-moderate psychedelic...

Mephedrone and Alcohol Interactions in Humans

Frontiers in Pharmacology January 28, 2020 Esther Papaseit, Clara Pérez‐mañá, Elizabeth B. de Sousa Fernandes Perna et al. 27 citations

Mephedrone (4-MMC, mephedrone) is a synthetic cathinone derivative included in the class of new psychoactive substances. It is commonly used simultaneously with alcohol (ethanol). The aim of the present study was to evaluate the interactions on subjective, cardiovascular and hormone effects and pharmacokinetics between mephedrone and alcohol in humans. Eleven male volunteers participated as...

Peripheral endocannabinoid concentrations are not associated with verbal memory impairment during MDMA intoxication

Psychopharmacology November 16, 2017 Eline Haijen, Magı́ Farré, Rafael de la Torre et al. 9 citations

Preclinical data have suggested involvement of the endocannabinoid (eCB) system in MDMA-induced memory impairment. Clinical research has shown that blockade of the 5-HT 2 receptor nulls memory impairment during MDMA intoxication. Interestingly, studies have demonstrated that the eCB and the 5-HT system interact. It was hypothesized that MDMA would cause an increase in eCB concentrations...

GC–MS Quantification Method for Mephedrone in Plasma and Urine: Application to Human Pharmacokinetics

Journal of Analytical Toxicology October 3, 2016 Eulàlia Olesti, Mitona Pujadas, Esther Papaseit et al. 41 citations

Increasing consumption has been observed among young people of new psychoactive substances, including synthetic cathinone derivatives. The most well known of these is mephedrone whose use has been related to acute intoxication and fatality. Several methods able to detect mephedrone have been reported, although to date, none have been applied to human pharmacokinetic studies in a controlled...
