Atypical tricyclic antidepressant medication
Pharmaceutical compound
Butriptyline , sold under the brand name Evadyne among others, is a tricyclic antidepressant (TCA) that has been used in the United Kingdom and several other European countries for the treatment of depression but appears to no longer be marketed.[ 1] [ 4] [ 5] [ 6] [ 7] Along with trimipramine , iprindole , and amoxapine , it has been described as an "atypical" or "second-generation" TCA due to its relatively late introduction and atypical pharmacology .[ 8] [ 9] It was very little-used compared to other TCAs, with the number of prescriptions dispensed only in the thousands.[ 10]
Medical uses
Butriptyline was used in the treatment of depression .[ 11] It was usually used at dosages of 150–300 mg/day.[ 12]
Side effects
Butriptyline is closely related to amitriptyline , and produces similar effects as other TCAs, but its side effects like sedation are said to be reduced in severity and it has a lower risk of interactions with other medications.[ 6] [ 7] [ 10]
Butriptyline has potent antihistamine effects, resulting in sedation and somnolence .[ 13] It also has potent anticholinergic effects,[ 14] resulting in side effects like dry mouth , constipation , urinary retention , blurred vision , and cognitive /memory impairment .[ 13] The drug has relatively weak effects as an alpha-1 blocker and has no effects as a norepinephrine reuptake inhibitor ,[ 15] [ 16] so is associated with little to no antiadrenergic and adrenergic side effects.[ 15] [ 14] [additional citation(s) needed ]

In vitro , butriptyline is a strong antihistamine and anticholinergic , moderate 5-HT2 and α1 -adrenergic receptor antagonist , and very weak or negligible monoamine reuptake inhibitor .[ 15] [ 20] [ 16] [ 19] These actions appear to confer a profile similar to that of iprindole and trimipramine with serotonin -blocking effects as the apparent predominant mediator of mood-lifting efficacy.[ 21] [ 19] [ 18]
However, in small clinical trials , using similar doses, butriptyline was found to be similarly effective to amitriptyline and imipramine as an antidepressant, despite the fact that both of these TCAs are far stronger as both 5-HT2 antagonists and serotonin–norepinephrine reuptake inhibitors .[ 15] [ 20] [ 22] As a result, it may be that butriptyline has a different mechanism of action , or perhaps functions as a prodrug in the body to a metabolite with different pharmacodynamics .
Pharmacokinetics
Therapeutic concentrations of butriptyline are in the range of 60–280 ng/mL (204–954 nmol/L).[ 23] Its plasma protein binding is greater than 90%.[ 3]
Chemistry
Butriptyline is a tricyclic compound , specifically a dibenzocycloheptadiene , and possesses three rings fused together with a side chain attached in its chemical structure .[ 24] Other dibenzocycloheptadiene TCAs include amitriptyline , nortriptyline , and protriptyline .[ 24] Butriptyline is an analogue of amitriptyline with an isobutyl side chain instead of a propylidene side chain.[ 10] [ 25] It is a tertiary amine TCA, with its side chain -demethylated metabolite norbutriptyline being a secondary amine .[ 26] [ 27] Other tertiary amine TCAs include amitriptyline , imipramine , clomipramine , dosulepin (dothiepin), doxepin , and trimipramine .[ 28] [ 29] The chemical name of butriptyline is 3-(10,11-dihydro-5H -dibenzo[a ,d ]cycloheptene-5-yl)-N ,N ,2-trimethylpropan-1-amine and its free base form has a chemical formula of C21 H27 N with a molecular weight of 293.446 g/mol.[ 1] The drug has been used commercially both as the free base and as the hydrochloride salt .[ 1] [ 4] The CAS Registry Number of the free base is 15686-37-0 and of the hydrochloride is 5585-73-9.[ 1] [ 4]
History
Butriptyline was developed by Wyeth and introduced in the United Kingdom in either 1974 or 1975.[ 5] [ 30] [ 31]
