Fluparoxan (GR-50,360) is a potent and highly selective α2-adrenergic receptor antagonist which was being investigated as an antidepressant but failed to show sufficiently significant efficacy for depression in clinical trials and never made it to the market.[1][2] In animal and/or human studies fluparoxan has been found to produce stimulation, tachycardia, hypertension, hyperthermia, penile erection, and pro-nociceptive effects, as well as antidepressant-like effects, panic, and anxiogenesis.[1][2][3][4]
