Randomized Controlled Trial
A double-blind, randomized, placebo-controlled study assessing the efficacy and tolerability of desvenlafaxine 10 and 50 mg/day in adult outpatients with major depressive disorder.
In an effort to establish the lowest effective dose of desvenlafaxine (administered as desvenlafaxine succinate), we assessed the efficacy, safety, and tolerability of 10- and 50-mg/day desvenlafaxine vs placebo for the treatment of major depressive disorder. ⋯ Both doses of desvenlafaxine failed to separate from placebo. However, in a companion study reported separately, desvenlafaxine 50 mg, but not 25 mg, separated from placebo. Taken together, these studies suggest that 50 mg is the minimum effective dose of desvenlafaxine for the treatment of major depressive disorder.
