The pathogenesis of flushing attacks in patients with malignant carcinoid tumors is attributed to the direct pharmacologic effect of excessive amounts of circulating serotonin. It was hoped that potent serotonin antagonists might relieve symptoms of the carcinoid syndrome in the inoperable patient. The nature of flushing attacks was studied in carcinoid patients and the influence thereon of 3 s...

In the spring of 1943, a 37-year-old Swiss chemist named Albert Hofmann had “a peculiar presentiment.” He believed that he had missed something in 1938, the year when he first synthesized the twenty-fifth compound of the lysergic acid diethylamide series, LSD-25. For eight years at Sandoz Pharmaceuticals, Hofmann was in charge of the ergot project, which involved synthesizing ergotamine molecul...

We estimated lifetime prevalence of psychedelic use (lysergic acid diethylamide (LSD), psilocybin (magic mushrooms), mescaline, and peyote) by age category using data from a 2010 US population survey of 57,873 individuals aged 12 years and older. There were approximately 32 million lifetime psychedelic users in the US in 2010; including 17% of people aged 21 to 64 years (22% of males and 12% of...

Systemic administration of lysergic acid diethylamide (LSD) to rats induces a behavioral syndrome--consisting of tremor, rigidity, Straub tail, hindlimb abduction, lateral head weaving and reciprocal forepaw treading--which is a reflection of increased activation of central serotonin receptors. Utilizing this behavioral measure, a marked supersensitivity to LSD was observed in rats whose seroto...

One of the main obstacles faced by translational neuroscience is the development of animal models of psychiatric disorders. Behavioural pharmacology studies indicate that psychedelic drugs, such as lysergic acid diethylamide (LSD) and dissociative drugs, such as phencyclidine (PCP), induce in healthy human volunteers psychotic and cognitive symptoms that resemble some of those observed in schiz...

This manuscript reviews the history and pharmacognosy of ergot, and describes the isolation/preparation, chemistry, pharmacodynamics, and pharmacotherapeutics of the major ergot alkaloids and their derivatives. A brief discussion of the hallucinogenic properties of lysergic acid diethylamide is also featured. An abbreviated form of the material found in this paper is presented in a 4-hour didac...

This study looked into the transformative effects and integration challenges of psychedelic experiences with psilocybin lysergic acid diethylamide (LSD) for Romanian population. The aim was to determine long-term individuals might encounter during process. employed a sequential mixed method design, using qualitative interpretative phenomenological analysis (IPA) six interview participants, foll...

Drugs active at G protein-coupled receptors (GPCRs) can differentially modulate either canonical or noncanonical signaling pathways via a phenomenon known as functional selectivity or biased signaling. We report biochemical studies showing that the hallucinogen lysergic acid diethylamide, its precursor ergotamine (ERG), and related ergolines display strong functional selectivity for β-arrestin ...
