Imipramine and 5HT re-uptake inhibition: a narrative
Abstract:
In 1960, the first paper on the pharmacology of imipramine, the 'original' antidepressive drug, was published in the British Journal of Pharmacology (Marshall et al. , 1960). It came from the Department of Clinical Research of the Crichton Royal Hospital, Dumfries, Scotland and not as might have been expected from a university department or the laboratories of a pharmaceutical firm. Under the circumstances, it seems relevant to record for the benefit of scientific historians, the somewhat tortuous chain of events that led to its publication.

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
