Duratia 90 mg is a medication primarily used to treat premature ejaculation in men. It contains dapoxetine hydrochloride, which belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). Dapoxetine works by increasing the levels of serotonin in the brain, which helps to delay ejaculation and improve control over ejaculation timing. It's important to use Duratia 90 mg as directed by a healthcare professional and to discuss any potential side effects or concerns with them.
