Abstract:

Duloxetine (Cymbalta^®) is an orally administered, selective serotonin and noradrenaline reuptake inhibitor (SNRI) that has been approved for the treatment of major depressive disorder (MDD).

Based on a considerable body of evidence, duloxetine at dosages ranging from 40 to 120 mg/day was effective in the short- and long-term treatment of MDD. Significant improvements versus placebo in core emotional symptoms as well as painful physical symptoms associated with depression, were seen in most, but not all, appropriately designed studies; results of meta-analyses suggested that improvements in these efficacy measures were apparent after 1-2 weeks' treatment with the highest recommended dosage of 60mg once daily. Short-term (≤15 weeks) administration of duloxetine at fixed or flexible dosages between 60 and 120 mg/day was noninferior to paroxetine 20mg once daily, noninferior or inferior to escitalopram 10-20mg once daily, and had a similar global benefit-risk (GBR) profile to that of venlafaxine extended-release (XR) 150-225 mg/day in the treatment of MDD. Longer-term (6-8 months) treatment with duloxetine was similar in efficacy to paroxetine and escitalopram. Duloxetine is generally well tolerated, although it may be appropriate to avoid initiating treatment with the 60 mg/day dosage, as this has been associated with a higher discontinuation rate due to adverse events in some (but not all) comparative studies with escitalopram and venlafaxine XR.

Definitive comparisons are awaited, although duloxetine seemingly provides a useful alternative to SSRIs and other SNRIs for the treatment of MDD. It also appears to be an attractive option for MDD patients presenting with painful physical symptoms.
