Introduction: Finasteride is a 5 a-reductase inhibitor to treat benign prostatic hyperplasia (BPH) and one of the adverse effects is the increase of depressive symptoms. D-004 is a lipid extract from the real palm fruit (Roystonea regia) that is effective to prevent prostatic hyperplasia by inhibiting 5 a-reductase and shows moderate antidepressant effects in the forced swimming test (FST) and tail suspension test. Objective: to compare the effects of D-004, Imipramine and Sertraline on the duration of behaviours under conditions of immobility, swimming and climbing in the forced swimming test. Methods: mice were randomly distributed in 8 groups: control (vehicle), 3 treated with D-004 (100, 250 and 500 mg/kg), 2 with Sertraline and 2 with Imipramine (30 and 50 mg/kg) respectively. Mice were placed in a glass cylinder containing 6 cm high column of water and their behaviours were quantified. Results: oral administration of D-004 (100, 250 and 500 mg/kg) during 14 days reduced the length of time of immobility with respect to the control group (17, 22 and 25 %), and significantly increased the behaviours at swimming by 1.58, 1.68 and 1.74 times. This is a moderate effect (25 %) if compared with Sertraline and Imipramine (³ 60 %) The doses of 250 and 500 mg/kg showed that climbing behaviours were 2.79 and 3.55 times higher than the control group. The results were similar to those of Imipramine but less effective. Conclusions: D-004 showed moderate antidepressant effect. This fact could help in the treatment of patients with benign prostatic hyperplasia, who reported similar depressive status.
