Femoxetine (Malexil, FG-4963) is a drug related to paroxetine that was being developed as an antidepressant by the pharmaceutical company Ferrosan in 1974. It functions as a selective serotonin reuptake inhibitor (SSRI). Development was halted for unknown reasons, perhaps to focus attention on paroxetine instead.
Dr. Jorgen Buus-Lassen of Ferrosan invented both femoxetine and paroxetine in the 1970s.
