Effect of acute (panel A) and subchronic (panel B) treatment with sildenafil in the forced swim test in reserpine-treated mice. In acute studies, sildenafil was administered i.p. 30 min before the test. In subchronic studies, sildenafil was administered once daily for 14 consecutive days. Reserpine was injected i.p. 240 min before the test. Control animals received 1 % Tween 80 + 1 % DMSO. Each experimental group consisted of 11–12 animals. Data are presented as means + SEM. ** p < 0.01, *** p < 0.001 as compared to the control group; ### p < 0.001 as compared to the reserpine-treated group (one-way ANOVA followed by Tukey post hoc test)
