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.

The results suggest that mirtazapine orally disintegrating tablets provide antidepressant efficacy and are a relatively well-tolerated treatment for depression in this patient population of elderly nursing home residents with medical and cognitive comorbidities.

Although lacking a placebo control, this naturalistic study suggests that mirtazapine orally disintegrating tablets were effective and well tolerated in this sample of depressed nursing home residents>or=85 years of age.

In this sample of depressed nursing home residents treated with mirtazapine orally disintegrating tablets, advanced age, medical illness, and cognitive impairment did not predict response. The findings suggest that these variables need not be viewed as obstacles to treatment.
