Context: Memantine is a low- to moderate-affinity, uncompetitive N-methyl-D-aspartate receptor antagonist. Controlled trials have demonstrated the safety and efficacy of memantine monotherapy for patients with moderate to severe Alzheimer disease (AD) but no controlled trials of memantine in patients receiving a cholinesterase inhibitor have been performed.
Objective: To compare the efficacy and safety of memantine vs placebo in patients with moderate to severe AD already receiving stable treatment with donepezil.

Background: Escitalopram is the single isomer responsible for the serotonin reuptake inhibition produced by the racemic antidepressant citalopram. The present randomized, double-blind, placebo-controlled, fixed-dose multicenter trial was designed to evaluate the efficacy and tolerability of escitalopram in the treatment of major depressive disorder.
Method: Outpatients with an ongoing DSM-IV major depressive episode (N = 491) were randomly assigned to placebo, escitalopram, 10 mg/day, escitalopram, 20 mg/day, or citalopram, 40 mg/day, and entered an 8-week double-blind treatment period following a 1-week single-blind placebo lead-in.
