Dapoxetine, the active ingredient in Duratia, belongs to a class of medications known as selective serotonin reuptake inhibitors (SSRIs). It works by increasing the activity of serotonin in the nervous system. Serotonin is a neurotransmitter involved in regulating mood, emotions, and the ejaculatory process. By inhibiting the reuptake of serotonin, dapoxetine prolongs the time it takes to ejaculate and improves control over ejaculation.
