Dapoxetine, marketed as Priligy and Westoxetin among others, is a medication used for the treatment of premature ejaculation (PE) in men 18–64 years old.[2][3] Dapoxetine works by inhibiting the serotonin transporter, increasing serotonin's action at the post synaptic cleft, and as a consequence promoting ejaculatory delay.[4] As a member of the selective serotonin reuptake inhibitor (SSRI) family, dapoxetine was initially created as an antidepressant.
