Photodecomposition of Lysergic Acid Diethylamide (LSD)

The paradoxical psychological effects of lysergic acid diethylamide (LSD).

BACKGROUND Lysergic acid diethylamide (LSD) is a potent serotonergic hallucinogen or psychedelic that modulates consciousness in a marked and novel way. This study sought to examine the acute and mid-term psychological effects of LSD in a controlled study. METHOD A total of 20 healthy volunteers participated in this within-subjects study. Participants received LSD (75 µg, intravenously) on on...

Lysergic acid diethylamide (LSD) for alcoholism: meta-analysis of randomized controlled trials.

Assessments of lysergic acid diethylamide (LSD) in the treatment of alcoholism have not been based on quantitative meta-analysis. Hence, we performed a meta-analysis of randomized controlled trials in order to evaluate the clinical efficacy of LSD in the treatment of alcoholism. Two reviewers independently extracted the data, pooling the effects using odds ratios (ORs) by a generic inverse vari...

D-lysergic acid diethylamide (LSD-25): a survey of the literature.

Effect of lysergic acid diethylamide (LSD-25) on morphine induced bradycardia.

Several antagonistic interactions between morphine and LSD-25 (lysergic acid diethylamide) have been demonstrated. LSD-25 antagonizes morphine induced analgesia in rats (1) and emesis in dogs (2). It also blocks the miotic action of morphine (3). On the other hand morphine blocks LSD-25 induced pyre xia in rabbits (4) and the central hypotensive effect of LSD-25 in dogs (5). Morphine produces m...

Stereospecific binding of D-lysergic acid diethylamide (LSD) to brain membranes: relationship to serotonin receptors.

D-[3H]LSD binds saturably, reversibly, and with a high affinity (KD = 10 nM) to rat brain membranes. The association and dissociation rates of binding are temperature dependent and fastest at 37 degrees C. Binding is enriched in crude microsomal (P3) membranes. D-[3H]LSD binding is stereospecific as L-LSD, the psychotropically inactive enatiomer, is 1000 times weaker than D-LSD as a displacing ...
