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...

The Effects of D-lysergic Acid Diethylamide Tartrate (lsd-25) on the Cholinesterases and Monoamine Oxidase in the Spinal Cord: a Possible Factor in the Mechanism of Hallucination.

Placebo reactions in a study of lysergic acid diethylamide (LSD-25).

Response of cluster headache to psilocybin and LSD.

The authors interviewed 53 cluster headache patients who had used psilocybin or lysergic acid diethylamide (LSD) to treat their condition. Twenty-two of 26 psilocybin users reported that psilocybin aborted attacks; 25 of 48 psilocybin users and 7 of 8 LSD users reported cluster period termination; 18 of 19 psilocybin users and 4 of 5 LSD users reported remission period extension. Research on th...

Interference with testing for lysergic acid diethylamide.

We found a high rate (4.2%) of positive results for lysergic acid diethylamide (LSD) by Emit in 1898 urine samples that were submitted primarily from psychiatric patients for drugs-of-abuse (DOA) testing. Specimens that tested positive for LSD by Emit subsequently tested negative for LSD with two RIAs. Furthermore, LSD was not detected in randomly selected Emit-positive urine samples by gas chr...
