Duratia 30 mg contains dapoxetine 30 mg, a medication used for the treatment of premature ejaculation (PE) in adult men. It belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs) and is designed to help improve control over ejaculation. Dapoxetine increases the activity of serotonin in the nervous system, which helps regulate the ejaculation reflex. This may allow men to delay ejaculation, increase control during sexual activity, and improve sexual confidence.
