چکیده
Objective: Hypericum perforatum has demonstrated antidepressant efficacy when compared to placebo, but comparisons with other antidepressants remain controversial. We assessed the efficacy and safety of Hypericum perforatum in comparison with fluoxetine, in a 8-week double-blind trial in patients with mild to moderate depression. Method: Seventy-two outpatients were randomly assigned to receive Hypericum perforatum 900 mg/day, fluoxetine 20 mg/day or placebo. Efficacy measures included the HAM-D 21 scale, the Montgomery-Åsberg Rating Scale, and the Clinical Global Impression. Safety was assessed with the UKU Side Effect Rating Scale. Results: Intention-to-treat analysis showed no differences between the mean scores of the three groups. In the analyses of observed cases, patients receiving Hypericum perforatum had the lowest remission rates (12%, p = 0.016) compared to fluoxetine (34.6%) and placebo (45%). Conclusions: Hypericum perforatum was less efficacious than both fluoxetine and placebo. Both drugs were safe and well-tolerated. Larger trials are needed for definite conclusions.
