"The duloxetine + mirtazapine combination is a particularly effective tool in the antidepressant arsenal. Duloxetine is a very high affinity blocker of both the serotonin and norepinephrine transporters, at 0.8 for the SERT and 7.5 for the NET respectively, resulting in increased serotonergic and noradrenergic neurotransmission, which results in improvements in mood, cognition, desire to work, motivation, greater skill at performing tasks effectively, memory, alertness, and keenness, while also alleviating depression, anxiety, and obsessive-compulsive ideation. Mirtazapine’s antagonism of the α2 receptors further preserves and enhances serotonergic and noradrenergic neurotransmission and its very high antagonism of the 5-HT2 receptors also alleviates depression and anxiety. Importantly, duloxetine is a moderate affinity inhibitor of the CYP2D6 enzyme, thereby increasing the plasma concentration of the substrate, mirtazapine, to between 2-5 times the normal levels. After beginning use of this regimen, symptoms such as prolonged headache, fatigue, and even a worsening of psychological symptoms tend to predominate for 3 weeks before going away. Therapeutic effects set in 3-4 weeks after beginning use, even if one has just discontinued a previous antidepressant.[1][2]"

"The duloxetine + mirtazapine combination is a particularly effective tool in the antidepressant arsenal.[3][4] Duloxetine is a very high affinity blocker of both the serotonin and norepinephrine transporters, at 0.8 for the SERT and 7.5 for the NET respectively,[5] resulting in increased serotonergic and noradrenergic neurotransmission, which results in improvements in mood, cognition, desire to work, motivation, energy, greater skill at performing tasks effectively, memory, alertness, and keenness, while also alleviating depression, anxiety, and obsessive-compulsive ideation.[6][7][8] Mirtazapine’s antagonism of the α2 receptors further preserves and enhances serotonergic and noradrenergic neurotransmission and its very high antagonism of the 5-HT2 receptors also alleviates depression and anxiety.[9] Importantly, duloxetine is a moderate affinity inhibitor of the CYP2D6 enzyme, thereby increasing the plasma concentration of the substrate, mirtazapine, to between 2-5 times the normal levels.[10] After beginning use of this regimen, symptoms such as prolonged headache, fatigue, and even a periodic worsening of psychological symptoms tend to predominate for 3 weeks before going away. Therapeutic effects set in 3-4 weeks after beginning use, even if one has just discontinued a previous antidepressant.[11]

This is strange. This review "Anttila SA, Leinonen EV (2001). "A review of the pharmacological and clinical profile of mirtazapine". CNS Drug Rev. 7 (3): 249–64. PMID 11607047." does not even mention duloxetine?
And neither does this one[1] Doc James (talk · contribs · email) 04:49, 16 December 2017 (UTC)[reply]
