Duratia?30?mg is a prescription medicine used to treat premature ejaculation (PE) in adult men. It contains dapoxetine, a short?acting selective serotonin reuptake inhibitor (SSRI), which helps increase levels of serotonin in the brain — a chemical that plays a key role in regulating the ejaculatory reflex. By enhancing serotonin action, Duratia helps delay ejaculation and improve control during sexual activity. What Duratia 30 mg Is Used For Primary use: Treatment of premature ejaculation in men aged 18–64. It’s not a treatment for erectile dysfunction (ED) itself, but it may improve sexual performance by extending the time before ejaculation and reducing performance anxiety. ow It Works Dapoxetine works by blocking the reuptake of serotonin in the brain, which increases serotonin’s availability in synapses and helps slow the ejaculatory process, giving better control and a longer duration before climax.
