title: Escitalopram (10-20 mg/day) is effective and well tolerated in a placebo-controlled study in depression in primary care.
abstract: Escitalopram was compared to placebo in moderately to severely depressed patients in primary care with citalopram as the active reference. Patients were randomized to receive flexible doses of 10-20 mg/day escitalopram (n=155), 20-40 mg/day citalopram (n=160), or placebo (n=154) over an 8-week double-blind period. The primary efficacy parameter was the change from baseline to last assessment in the Montgomery-Asberg Depression Rating Scale total score. Escitalopram produced a statistically significant therapeutic difference of 2.9 points (P=0.002) compared to placebo, and escitalopram was consistently and statistically significantly more efficacious than placebo from week 1 onwards. Analysis of Clinical Global Impression-Severity and Clinical Global Impression-Improvement confirmed the primary efficacy results. By week 8, significantly more patients had responded to treatment with escitalopram than with citalopram (P=0.021) or placebo (P=0.009). Escitalopram was as well tolerated as citalopram and had a similar adverse event profile. Both escitalopram- and citalopram-treated patients had placebo-level adverse event withdrawal rates (3% and 4%, respectively). This study demonstrates the consistent antidepressant efficacy and excellent tolerability of escitalopram 10-20 mg/day in primary care patients with major depressive disorder.
