However, it is important to note that the efficacies of most of the antidepressants in this review differed only slightly.

However, unlike most other antidepressants, though similarly to venlafaxine, these effects are mostly mediated through downstream modulation of the endogenous opioid system, of which in the case of mirtazapine the μ-opioid and κ < sub > 3 </ sub >- opioid receptors are mainly involved.
