Duratia 90 is a medication used to treat premature ejaculation (PE) in men. Premature ejaculation is a common sexual problem where a man ejaculates too quickly during sexual activity, often before he or his partner desires. Duratia 90 contains the active ingredient dapoxetine, which is a selective serotonin reuptake inhibitor (SSRI). Duratia 90 is specifically designed to help men with premature ejaculation. It works by increasing the levels of serotonin in the brain, which can help delay ejaculation and improve control over ejaculation timing.
