Randomized Controlled Trial Multicenter Study
Escitalopram and duloxetine in major depressive disorder: a pharmacoeconomic comparison using UK cost data.
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) are approved for the treatment of major depressive disorder (MDD). The allosteric SSRI escitalopram has been shown to be at least as clinically effective as the SNRIs venlafaxine and duloxetine in MDD, with a better tolerability profile. In addition, escitalopram has been shown to be cost saving compared with venlafaxine. ⋯ Escitalopram was associated with significantly lower duration of sick leave and significant savings in the total cost compared with duloxetine; it dominated duloxetine when effectiveness was assessed on the SDS scale. Indirect costs due to sick leave accounted for the most substantial portion of the total cost and should, therefore, be an important consideration when pharmacoeconomic comparisons between treatments are made from the societal perspective. The link between decrease in absenteeism and early (8-week) clinical improvement suggested in the additional analyses may explain the reduced sick leave observed with escitalopram, given its superior short-term efficacy compared with duloxetine (demonstrated in the underlying clinical trial).
