Efficacy and tolerability of citalopram in comparison with fluvoxamine in depressed outpatients: a double-blind, multicentre study. The LUCIFER Group

Abstract

In 16 depression clinics in hospitals and outpatient facilities in the Netherlands, a study was performed to evaluate and compare the efficacy and tolerability of citalopram and fluvoxamine and to determine the difference in the incidence of gastrointestinal side-effects. A total of 217 patients with a depressive disorder (DSM-III-R criteria) and a score of at least 16 on the Hamilton rating scale for depression were randomized to treatment. The results of this study indicate that the two drugs are equally effective. The adverse events occurring during treatment show a similar pattern between the two drugs, but citalopram is better tolerated than fluvoxamine. Citalopram induces fewer gastrointestinal adverse events compared with fluvoxamine. However, this did not affect the drop-out rates.
