Patients with major depression can show improvement after only one week of therapy with the selective serotonin reuptake inhibitor, escitalopram.
Clinical Global Impression-Improvement scores improved at week one with a dosage of 10 milligrams per day, say researchers from the Clinical Research Centre in Glasgow, Scotland and International Clinical Research in Copenhagen, Denmark.
The patients participating in this eight-week, double-blind trial all received one week of placebo. All had major depressive disorder. In week two, the investigators randomised 191 to received escitalipram and 189 patients to placebo.
Montgomery-Asberg Depression Rating Scale (MADRS) scores improved in the patients randomised to escitalopram; their Clinical Global Impression-Severity scores improved in week three. “Primary efficacy analysis of adjusted mean change in MADRS total score from baseline showed a statistically significantly larger effect for escitalopram than for placebo,” the researchers say. At eight weeks, the treatment different was 2.7 points for escitalopram patients compared to placebo patients.
