Amitriptyline is an efficacious antidepressant drug .
It is , however , also associated with a number of side effects .
Degree of placebo response and severity of depression at baseline may moderate drug-placebo efficacy differences
BACKGROUND Amitriptyline is a tricyclic antidepressant that was synthesis ed in 1960 and introduced as early as 1961 in the USA , but is still regularly used .
It has also been frequently used as an active comparator in trials on newer antidepressants and can therefore be called a ' benchmark ' antidepressant .
However , its efficacy and safety compared to placebo in the treatment of major depression has not been assessed in a systematic review and meta- analysis .
OBJECTIVES To assess the effects of amitriptyline compared to placebo or no treatment for major depressive disorder in adults .
Mirtazapine vs. amitriptyline vs. placebo in the treatment of major depressive disorder.
Patients ( n = 150 ) were r and omized to a 6-week , double-blind study to evaluate the relative efficacy and safety of mirtazapine , amitriptyline , and placebo in the treatment of major depressive disorder symptoms . Average daily modal doses were mirtazapine , 18 mg ; amitriptyline , 111 mg ; and placebo , 4.6 capsules . Mirtazapine- and amitriptyline-treated patients had statistically significantly greater mean Hamilton Rating Scale for Depression ( HAM-D ) score reductions ( weekly visits 1 , 2 , 4 , and endpoint ) compared to placebo . These findings were supported by the Montgomery-Asberg Depression Rating Scale ( MADRS ) ; the Zung Self-rating Depression Scale ( SDS ) ; and the Clinical Global Impressions ( CGI ) scales . Somnolence and weight gain were the only adverse clinical experiences ( ACEs ) reported substantially more often by mirtazapine-treated patients than by those in the placebo group . However , more amitriptyline-treated patients reported decreased visual accommodation , dry mouth , dyspepsia , constipation , tachycardia , hypertension , hypotension , discoordination , dizziness , and tremor than mirtazapine- or placebo-treated patients . Results of this study indicate that mirtazapine is more effective than placebo in the treatment of these patients , and superior to amitriptyline in respect to anticholinergic and cardiovascular effects
