Mirtazapine was significantly more effective than a serotonin-noradrenaline reuptake inhibitor ( venlafaxine only , two trials , n = 415 ) at two weeks ( OR 2.29 , 95 % CI 1.45 to 3.59 ) and at the end of acute-phase treatment ( OR 1.53 , 95 % CI 1.03 to 2.25).In terms of dropouts , there was no robust evidence to detect a difference between mirtazapine and other antidepressants .
Mirtazapine was more likely to cause weight gain or increased appetite and somnolence than SSRIs but less likely to cause nausea or vomiting and sexual dysfunction .
AUTHORS ' CONCLUSIONS Some statistically significant and possibly clinical ly meaningful differences between mirtazapine and other antidepressive agents were found for the acute-phase treatment of major depression .
Mirtazapine is likely to have a faster onset of action than SSRIs during the acute-phase treatment .
Dropouts occur similarly in participants treated with mirtazapine and those treated with other antidepressants , although the adverse event profile of mirtazapine is unique
BACKGROUND Mirtazapine has a unique mechanism of antidepressive action and is one of the commonly used antidepressants in clinical practice .
OBJECTIVES The aim of the present review was to assess the evidence on the efficacy and acceptability of mirtazapine compared with other antidepressive agents in the acute-phase treatment of major depression in adults .
A randomized, double‐blind, 24‐week study comparing the efficacy and tolerability of mirtazapine and paroxetine in depressed patients in primary care
& NA ; Primary care patients with a major depressive disorder and 17‐item Hamilton Rating Scale for Depression ( 17‐HAM‐D ) score > 18 were r and omized to 24 weeks of treatment with mirtazapine  30‐45 mg/day ( n= 99 ) or paroxetine 20‐30 mg/day ( n=98 ) . Both treatments were efficacious in improving depressive symptomatology , as assessed by group mean 17‐HAM‐D scores , percentages of HAM‐D responders and remitters and Clinical Global Improvement responders . The mirtazapine group showed statistically significantly larger decreases from baseline in group mean 17‐HAM‐D scores at weeks 1 , 2 and 4 , and the difference with the paroxetine group reached the level of clinical relevance at weeks 2 and 4 . Antidepressant efficacy was maintained throughout both the acute and continuation phase of treatment . Both treatments were well tolerated . The only adverse event with a statistically significantly higher incidence in the mirtazapine group was fatigue . Statistically significantly more paroxetine‐treated patients complained of increased sweating , headache and nausea . The results demonstrate that both mirtazapine and paroxetine were efficacious and well tolerated when used for 24 weeks in depressed patients treated in primary care . An observed difference in efficacy favouring mirtazapine between weeks 1 and 4 indicates that mirtazapine patients had improved earlier compared to those on paroxetine , and corroborates similar findings in other comparisons of mirtazapine versus selective serotonin reuptake inhibitors
