Butriptyline (Evadene, Evadyne, Evasidol, Centrolese) is a tricyclic antidepressant (TCA) which has been used in Europe since 1974.[1][2][3][4][5] It is the isobutyl side chain homologue of amitriptyline and produces similar effects to it, but with less marked side effects like sedation and interactions with adrenergic drugs.[1][5][6]

In vitro, butriptyline is a strong antihistamine and anticholinergic, moderate 5-HT2 and α1-adrenergic receptor antagonist, and weak serotonin reuptake inhibitor, with negligible affinity for the norepinephrine and dopamine transporters.[7][8][9] These actions appear to confer a profile similar to that of iprindole and trimipramine with serotonin-blocking effects as the predominant mediator of mood-lifting efficacy.[10][11][12]

However, in clinical trials, using similar doses, butriptyline was found to be even more effective than amitriptyline as an antidepressant, despite the fact that amitriptyline is far stronger as both a 5-HT2 antagonist and serotonin-norepinephrine reuptake inhibitor.[7][8][9][13] As a result, it may be that butriptyline, in vivo, functions as a prodrug to a metabolite with more appreciable pharmacodynamics.
