Duratia 30 mg is a medication primarily used to treat premature ejaculation (PE) in men. It contains the active ingredient dapoxetine, which is a selective serotonin reuptake inhibitor (SSRI). Dapoxetine works by increasing the level of serotonin in the nervous system, which can help to improve control over ejaculation and extend the time before ejaculation occurs. Dapoxetine, the active ingredient in Duratia 30 mg, functions by inhibiting the serotonin transporter, increasing serotonin's action at the post-synaptic cleft, and prolonging the ejaculatory latency period. It essentially helps in delaying the ejaculation process, providing more control during sexual activity.
