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 .
Effects of the serotonin transporter gene promoter polymorphism on mirtazapine and paroxetine efficacy and adverse events in geriatric major depression.
BACKGROUND The " long/short"polymorphism ( 5HTTLPR ) in the promoter of the serotonin transporter gene ( SLC6A4 ) has been proposed as a pharmacogenetic marker for antidepressant efficacy . Some but not all studies have found that the short form of 5HTTLPR ( S allele ) results in decreased efficacy of selective serotonin reuptake inhibitors . OBJECTIVE To determine if the 5HTTLPR polymorphism influences the efficacy and tolerability of mirtazapine and paroxetine hydrochloride , 2 frequently prescribed antidepressants with differing pharmacologic profiles , in geriatric depression . DESIGN Double-blind , r and omized 8-week study . SETTING Eighteen academic and private outpatient clinics . PATIENTS We evaluated 246 cognitively intact patients 65 years or older with major depression . INTERVENTIONS Antidepressant therapy with 15 to 45 mg/d of mirtazapine ( n = 124 ) or 20 to 40 mg/d of paroxetine ( n = 122 ) . MAIN OUTCOME MEASURES The Hamilton Depression Rating Scale-17 and Geriatric Depression Scale , severity of adverse events and dosing compliance indexes , and discontinuations due to adverse events . Outcome measures were stratified according to 5HTTLPR genotypes . RESULTS Geriatric Depression Scale scores indicated that S allele carriers treated with paroxetine showed a small impairment in antidepressant response . Among mirtazapine-treated patients , there was little indication that the 5HTTLPR genotype affected antidepressant efficacy . However , the 5HTTLPR polymorphism had a dramatic effect on adverse events . Among paroxetine-treated subjects , S allele carriers experienced more severe adverse events during the course of the study , achieved significantly lower final daily doses , and had more discontinuations at days 14 , 21 , 28 , 42 , and 49 . Surprisingly , among mirtazapine-treated subjects , S allele carriers had fewer discontinuations due to adverse events , experienced less severe adverse events , and achieved higher final daily doses . CONCLUSIONS These results support the hypothesis that the S allele of 5HTTLPR at the SLC6A4 locus is associated with a poor outcome after treatment with selective serotonin reuptake inhibitors . However , the major effect was on the tolerability of these drugs rather than efficacy . Results from mirtazapine-treated patients indicate that the effect of this polymorphism on outcome may depend on the mechanism of antidepressant action
