Evaluation of the cost effectiveness of escitalopram versus venlafaxine XR in major depressive disorder
Abstract Aim : To assess the relative cost effectiveness of escitalopram compared with venlafaxine XR in patients with major depressive disorder ( MDD ) . Methods : An economic evaluation was conducted alongside a double-blind , multinational , r and omised clinical trial and examined the costs and quality of life of 251 patients taking escitalopram versus venlafaxine . Out patients fulfilling criteria for MDD were r and omised to receive oral escitalopram 10–20 mg/day or venlafaxine 75–150 mg/day for 8 weeks . Patient-reported outcomes ( EuroQOL question naire , Quality of Life Depression Scale ) , use of medical services and absence from work ( relating to the previous 3 months ) were recorded at baseline , with repeated measurements at week 8 . Unit costs in year values were applied to the re source utilisation data . A cost-effectiveness analysis was performed using the EuroQOL score as the effectiveness measure . The perspective was that of the healthcare payer , with a societal perspective considered in a sensitivity analysis . Results : Statistically significant improvements in patient-reported outcomes ( vs baseline ) were observed in both groups after 8 weeks ’ treatment . Patients treated with escitalopram tended to report fewer problems on the EuroQOL dimensions than venlafaxine recipients . Mean per-patient costs in euros ( € , year 2003 values ) for the escitalopram group , compared with the venlafaxine group , were 32 % lower ( € 110 vs € 161 ) from a healthcare perspective , although this was not a statistically significant difference . Differences were related to lower drug acquisition costs and fewer hospitalisations  for escitalopram than venlafaxine recipients . A multivariate model adjusting for baseline characteristics showed that escitalopram  reduced direct costs compared with venlafaxine ( p = 0.007 ) . Bootstrapped distributions of the incremental cost-effectiveness ratios also showed similar effectiveness but lower costs for escitalopram compared with venlafaxine . Inclusion of indirect costs led to similar results . Conclusion : This prospect i ve economic analysis suggests that escitalopram has similar effectiveness to venlafaxine in the treatment of MDD , but may be associated with lower healthcare costs . These findings are consistent with previously published economic evaluations
