Adrenergic receptor subtype activation by (+)-, (−)- and (±)-norephedrine in the pithed rat
, 1987 The ability of (±)-norephedrine (phenylpropanolamine) and its component isomers, (+)- and (-)-norephedrine, to activate adrenergic receptor subtypes in the cardiovascular system of the urethane/chloralose-anaesthetized pithed rat has been investigated ...

An ETH‐LAD trip with unfavourable consequences: A case report
British Journal of Clinical Pharmacology, EarlyView.Numerous analogues of the psychedelic and internationally controlled hallucinogen LSD have been described; however, only a limited number have been systematically investigated. This report presents the first case with an analytically confirmed ingestion of ETH‐LAD (6‐ethyl‐6‐nor‐lysergic acid diethylamide), the N‐ethyl derivative of LSD.
